Template:Short description Template:Pp-pc Template:Use mdy dates Template:Infobox criminal

Dennis Lynn Rader (born March 9, 1945), better known as the BTK Strangler or simply BTK,Template:NoteTag is an American serial killer and rapist who murdered at least ten people in Wichita and Park City, Kansas, between 1974 and 1991. Although he occasionally killed or attempted to kill men and children, Rader typically targeted women. His victims were often attacked in their own homes, then bound, sometimes with objects from their homes, and either suffocated with a plastic bag or manually strangled with a ligature.<ref name="Siegel2012">Template:Cite book</ref> In addition, he stole keepsakes from his female victims, including underwear, driver's licenses, and personal items.

Rader often sent taunting letters to police and media outlets, describing his crimes in detail.<ref>Template:Cite book</ref><ref>Template:Cite book</ref> In 2004, after a thirteen-year hiatus, Rader resumed sending letters, leading to his 2005 arrest and subsequent guilty plea. He is currently serving ten consecutive life sentences at the El Dorado Correctional Facility.<ref name="kdocrepository.doc.ks.gov"/>

Life and backgroundEdit

Dennis Lynn Rader was born in Pittsburg, Kansas, on March 9, 1945. His parents were bookkeeper Dorothea Mae Rader (Template:Née) and Kansas Gas Service worker William Elvin Rader.<ref>Template:Cite book</ref><ref>Template:Cite book</ref><ref>Template:Cite news</ref> He was the eldest of four sons. Growing up in Wichita, Rader later recalled feeling ignored by his mother. Both of his parents worked long hours and paid little attention to their children at home.<ref name="news.au.com">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

From a young age, Rader harbored sadistic sexual fantasies about torturing "trapped and helpless" women.<ref name="news.au.com"/><ref>Template:Cite magazine</ref> He also exhibited zoosadism by torturing, killing and hanging small animals.<ref>Template:Cite book</ref><ref name="owlcation">Template:Cite news</ref> Rader acted out sexual fetishes for voyeurism, autoerotic asphyxiation and cross-dressing, often spying on female neighbors while dressed in women's clothing, including women's underwear that he had stolen. He also masturbated with ropes or other bindings around his arms and neck.<ref>Template:Cite book</ref>

Years later, during his "cooling off" periods between murders, Rader would take pictures of himself wearing women's clothes and a female mask while bound. He later admitted that he was pretending to be his victims as part of his sexual fantasy.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> However, Rader kept his proclivities well hidden, and was widely regarded in his community as "normal, polite, and well mannered."<ref name="owlcation" />

After graduating from Wichita Heights High School,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Rader attended Kansas Wesleyan University. He received only mediocre grades and dropped out after one year. Rader served in the United States Air Force from 1966 to 1970.<ref name="kansas.com">Template:Cite news</ref> On discharge, he moved to Park City, a suburb of Wichita, where he worked in the meat department of an IGA supermarket where his mother was employed as a bookkeeper.<ref name="media.kansas.com">Template:Cite news</ref>

Rader married Paula Dietz on May 22, 1971. They had two children, Kerri and Brian.<ref name="InvestigationDiscovery">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="kansas.com-2005-07-27" /> He attended Butler County Community College in El Dorado, earning an associate degree in electronics engineering in 1973.<ref name="InsideStory">Template:Cite book</ref> He then enrolled at Wichita State University and graduated in 1979 with a Bachelor of Science degree, majoring in administration of justice.

Rader initially worked as an assembler for the Coleman Company, an outdoor supply company. He then worked at the local Wichita office of ADT Security Services from 1974 to 1988, where he installed security alarms. Ironically, many of his clients were concerned homeowners seeking security from his own killings as BTK.<ref name="InvestigationDiscovery" /><ref>Template:Cite news</ref> Rader was a field operations supervisor for the Wichita area for the 1990 federal census.<ref name="McClellan">Template:Cite book</ref>

By the 2000s, the public's memories of the murders had begun to fade. Local author Robert Beattie began writing a book about the killings, Nightmare in Wichita, after being shocked that many young people he spoke to had never heard of the BTK case. Hungry for attention, Rader re-emerged as BTK in 2004 after learning that the book was being written.<ref>The Wichita Eagle, 2005</ref>

Case historyEdit

Confirmed murdersEdit

Otero murdersEdit

On January 15, 1974, Rader murdered four members of the Otero family in Wichita.<ref name="Potter2013">Template:Cite news</ref> The victims were Joseph Otero Sr. (38), Julia Maria "Julie" Otero (33), Joseph "Joey" Otero II (9) and Josephine "Josie" Otero (11). Their bodies were discovered by the family's three older children, who had been at school at the time of the killings.<ref name="Potter2013" /><ref>Template:Cite news</ref> On the morning of the murders, Rader parked his car and walked to the Otero home, scaled a fence, and cut the phone lines when in the backyard. It was after this that Joseph Jr let the dog out the backdoor to the backyard, and Rader confronted him and forced his way into the home at gunpoint. Initially, the family thought he was pulling a prank; Rader asserted that it was not a joke and clarified that he had a .22 hollow point pistol.

Rader told the Otero family that he was wanted in California before ordering them at gunpoint to lie on the living room floor. Then, he led the family into a bedroom and bound them with rope he had prepared ahead of time. Joseph and Joey were on the floor, while Julie and Josie were on the bed.<ref name="confession" /> The family began complaining of circulation issues. Joseph Otero Sr complained of a cracked rib, so Rader put a pillow under him. Rader later stated that it was around this time that he decided to kill them.<ref name="confession" /> Rader covered Joseph's head with a plastic bag, which he then secured with ropes. After Joseph chewed a hole in the bag, Rader replaced it, causing him to slowly suffocate. Rader strangled Julie with a rope. At one point she regained consciousness and pled for mercy for her children, prompting Rader to kill her.<ref name="confession" /> Rader then placed another plastic bag, followed by two T-shirts and an additional bag, over Joey's head. Rader watched him struggle from a chair set up in the bedroom.<ref name="confession" />

After the rest of the family was murdered, Rader took Josephine down to the basement. Rader undressed Josephine and tied a noose around a sewer pipe in the basement. Rader asked Josephine if her father had a camera so he could take pictures, to which she responded no. Rader then hung the girl in the basement and masturbated as he watched her struggle on the rope.<ref name="confession" /> On the way out of the house, he got in the Otero family car and drove it to the parking lot of a Dillons grocery store. He realized that he had dropped a knife in the backyard of the Otero home, so he drove his car back to the house to retrieve it.<ref name="confession" />

After his 2005 arrest, Rader confessed to the Otero murders.<ref name="confession">Template:Cite news</ref> He claimed that he first targeted the family two months prior, when he spotted Julie leaving to take her children to school, and stalked them for 2–3 weeks.<ref name="confession" />

Murder of Kathryn BrightEdit

Rader planned to murder Kathryn Bright (21), referring to her as "Project Lights Out".<ref name="AndersonCooper360-2006" /> Rader picked her for his next murder victim after he spotted her entering her house with a friend. He had no knowledge of her younger brother Kevin (19) living at the same house, which might have dissuaded him from targeting her, as he was trying to "stay away from the males as much as possible" in order to make the killings easier.<ref name="statesumevidence">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

On April 4, 1974, Rader broke into the home through a sliding glass door in the back, to find no one was home yet. He began sweeping up the glass to try to minimize suspicion when Kathryn did arrive. The delicate trigger of his pistol caused an accidental discharge. He feared that the smell of gunpowder would alert Bright. She came home shortly with Kevin. He told them that he was a wanted man from California, and needed money and food. He was described as a stocky man wearing a silver wrist watch, "sweating profusely." Rader forced the Brights into the southeast bedroom, where he made Kevin tie Kathryn up, before Rader bound Kevin himself. Rader used household supplies, including bandanas, as restraints in order to distinguish the crime from the Otero murders. Kevin and Kathryn were separated into different rooms with Kevin tied to a bedpost, and Kathryn to a chair. Rader turned on the stereo system in the living room to drown out any sounds of struggle, which he later claimed was a trick he learned from "detective magazines".<ref name="statesumevidence" />

Rader returned to the bedroom where Kevin was restrained to strangle him, but Bright had freed himself. Rader then pulled his firearm and a struggle ensued, during which Kevin was shot in the forehead. Rader then attempted to strangle Kevin again, resulting in a similar struggle in which two more shots being fired: one landing just above Kevin's mouth and the other grazing him. Kevin played dead until Rader left the room, then ran from the house. He flagged down neighbors, who took him to the hospital and called police.<ref name="CNNVicBro">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

When Rader reentered her room, Kathryn asked about the gunshots. Rader told Kathryn that he had shot her brother, at which point she fought back with gusto. Kathryn's resistance proved too strong for Rader to strangle her as planned, so Rader resorted to stabbing her repeatedly in the area under her ribcage. Rader heard Kevin call for help during the struggle. Once Kathryn was dead, Rader grabbed her keys, ran outside, and tried unsuccessfully to start Bright's truck. When it did not start, Rader ran to his car, which was parked at Wichita State University. Kathryn was alive when police arrived at her house, holding a telephone in her hands but partially verbally unresponsive. Bright died in emergency surgery from multiple stab wounds and strangulation.<ref name="statesumevidence" />

Murder of Shirley Ruth RelfordEdit

On March 17, 1977, Rader had a different victim planned for the day, but the victim was not home. He was frustrated by this and decided to find a random person to kill instead. While looking for a potential victim, he came across Shirley's son, Steve (6), walking down the street. Rader approached Steve, claiming to be a detective, and asked him if he could identify individuals in a photo. Rader showed Steve a photo of his wife and daughter, who Steve mistakenly identified as his mother and sister. He then followed Steve back to his mother's house.

At the Relford residence, Rader asked Shirley if she could identify the same photo. During this interaction, Rader pulled a gun and forced his way into the home. He claimed that he was a wanted man, and that they were being robbed. Rader attempted to tie up the three Relford children but struggled to do so, leading him to force the children into a bathroom, which he barricaded with Shirley's assistance. Rader reported giving the kids toys and supplies to keep them "comfortable" while he murdered their mother. He threatened to shoot the children if they broke free. After this, Rader took Relford to the rear bedroom. Relford vomited before being tied to her bedpost by her legs and handcuffed. Rader strangled her with rope after placing a plastic bag over her head. During the murder, Shirley was sick and asked for water, which Rader provided prior to strangling her.

Rader later confessed that he intended to eventually kill the children in the bathroom. However, the family phone rang and one of the children shouted that it was someone who would be visiting shortly. This caused Rader to flee the home.

Murder of Nancy Jo FoxEdit

Rader had been stalking Nancy Jo Fox (25) for some time and had decided he was going to kill her; he gave her the name "Project Foxhunt".<ref name="AndersonCooper360-2006" />

On December 8, 1977, Rader broke into Fox's home through a back window, after discovering she was out. After some time, Fox returned and began screaming at Rader to leave her house and that she was going to call the police. Rader informed her that her phone lines were cut and she would not be able to make any calls. Rader informed her that he intended to restrain her, take photographs of her, and rape her. He let Fox smoke a cigarette before this.

Rader allowed Fox to go to the bathroom after she assured him that she could not escape. Rader ordered Fox to come out of the bathroom partially undressed. Rader began to undress and he ordered her to lay down when she emerged from the bathroom. Fox resisted when Rader tried to remove her remaining clothing. Rader then began putting handcuffs on Fox, to which she protested and questioned the need for. Rader told her, "that's part of my deal. I got to have them or it won't work." Rader then began to crawl on top of Fox, and wrapped his belt around her neck. He would repeatedly loosen and tighten the belt, allowing her to come close to unconsciousness and then bring her back, before eventually killing her.

The following day, Rader called police from a payphone, telling them they would find Fox's body at her home.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

BTK asks for recognitionEdit

File:BTK Now Call the Chief.png

The subliminal message to Rader which was flashed by KAKE-TV in 1978

On February 10, 1978,<ref name="KAKEBTKBack2005">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Rader sent another letter to Wichita television station KAKE claiming responsibility for the murders.<ref name="McClellan" /> He suggested many possible names for himself, including "BTK." He demanded media attention in this second letter, saying, "How many do I have to kill, before I get a name in the paper or some national attention?" A poem was enclosed titled "Oh! Death to Nancy," a parody of the lyrics to the American folk song "O Death".<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="douglas2007">Template:Cite book</ref> In the letter, Rader claimed to be driven to kill by "factor X," which he characterized as a supernatural element that also motivated Jack the Ripper, the Son of Sam and the Hillside Stranglers.<ref>Template:Cite news</ref> He also asked for the police to send him a hidden message. In response, and with the knowledge that the BTK killer watched KAKE, police decided to flash a subliminal message during one of the station's evening newscasts for a split second. The message stated: "Now call the chief," and featured a drawing of an upside-down pair of glasses, which were found at the Fox crime scene.<ref name="KAKEBTKBack2005" /><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> They hoped the message would influence the killer to turn himself in, but it was unsuccessful.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Attempted murder of Anna WilliamsEdit

During this time, Rader also intended to kill others, such as Anna Williams (63), who, in 1979, escaped death by returning home much later than expected. Rader explained during his confession that he became obsessed with Williams and was "absolutely livid" when she evaded him. He recalled spending hours waiting at Williams' home but becoming impatient and leaving when she did not return from visiting friends.<ref name="Bardsley">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Murder of Marine HedgeEdit

Rader had been stalking Marine Hedge (53) for some time and had given her the name "Project Cookie".<ref name="AndersonCooper360-2006"/> She lived only a few houses up from Rader, which made him select her just to see if he could murder one of his neighbors. Rader was attending a cub scouts outing on April 27, 1985, the night of the murder.<ref>Template:Cite news</ref> He had faked a headache, blaming the rainy and muddy weather for his sickness, saying he was going to bed early. Instead of going to bed, he quietly left and drove a little bit to a deserted area where he quickly changed out of his cub scouts attire. He then drove to a bowling alley across the street from Brittany Center at 21st Street and Woodlawn. He walked in, ordered a beer, swished it in his mouth, and splashed it on his face and clothes. He then called a taxi using a fake slurred drunk voice. He was dropped off one street down from his and Hedge's street.

Rader cut the phones line to Hedge's home and managed to break into the home without damaging it too much. He then hid in a closet. After some waiting, Hedge came home with her boyfriend, leading Rader to wait even longer in the bedroom closet until he left, and for Hedge to get into bed. After he was confident Hedge was in bed, he crept out of the closet and quickly flipped on the bathroom light switch. Hedge woke up and began screaming. Rader subdued and handcuffed Hedge before strangling her to death. Rader then wanted to remove her from the house to "tie her up and take pictures of her." After finding her car keys and collecting mementos, Rader stripped Hedge and dragged her out to her car. He drove her to the Christ Lutheran Church, where he was a long-time member and keyholder. He dragged Hedge's body into the building and covered the windows before turning on the lights, ensuring no light would be visible from the outside. He then began positioning the body in the church and taking photographs of the corpse.

As daylight was approaching, Rader cleaned the scene, removed the garbage bags off the windows, turned off the lights, and returned the body to the trunk. Rader drove a little distance away, and dumped the nude body of Hedge in a remote ditch and covered her with brush.

Murder of Vicki WegerleEdit

At this time, Rader was working for ADT and was out working when he saw Vicki Wegerle (28) get into her car. He stalked her for a little bit, before learning she played piano after hearing her playing it when prowling around outside her house. He referred to her as "Project Piano".<ref name="AndersonCooper360-2006">Template:Cite news</ref>

On September 16, 1986, Rader used one of the company's hard-hats, and a Southwest Bell manual to act as a repairman or technician for the telephone company. Rader first gained entry into Wegerle's neighbor's house, and pretended to do telephone work, before leaving and knocking on Wegerle's door. He did this to make her less suspicious. Once in the house, Rader told Wegerle he had to check the "telephone terminals." Wegerle directed him to the phone near the dining room table. Rader made small talk with Wegerle as he pretended to check the phone. After declaring the phone line looked okay, Rader pulled a gun on Wegerle and instructed her to go to the bedroom.

Wegerle told Rader that her husband would be home soon, but he persisted. Rader forced her in to the bedroom, where Wegerle broke free of her bonds and fought back. She scratched Rader's face hard enough that, at the time of his confession 20 years later, Rader testified that he "probably still ha[d] the scratch somewhere ... if you looked." The struggle upset the Wegerles' dogs, who began barking. Rader grew nervous, because the windows were open and he did not know when Wergele's husband would be home. Rader did not have much time but he took pictures after he killed her for "sexual purposes."

Rader fled with the Wegerle car, and passed Vicki's husband on the way out. Rader parked the car in a grocery store parking lot, and drove back home in his car. As he passed the Wegerle home, he saw EMS responding.

Murder of Dolores DavisEdit

Rader had seen Dolores Davis (62) not far from where he lived, and stalked her for a while. Rader codenamed Davis "Project Dogside" because of the dog kennels north of her home.<ref>Template:Cite news</ref> Rader "cased" the Davis home many times trying to figure out a plan, being unable to figure out a way to break in.<ref name="Dooley2019" />

Rader used a Trappers Scout outing as cover for the murder. On January 18, 1991, the Trappers were having their annual "dead of winter" outing at Harvey County Park West. Rader went to the park and set up camp before fabricating a story and leaving. Rader then drove to his parents' house and got undressed out of the trapping scout clothes.<ref name="CNNAugust2023" /> Rader then drove to Park City Baptist Church, to which he had a key to the church because of his Boys Scouts duties. Rader left the church, walking through wheat fields and cutting through a cemetery to get to Davis's home. The severe cold drove Rader to break-in by smashing the window rather than trying to break in more quietly.<ref name="31 Years" />

The time was 10:30 p.m. to 11 p.m. when Rader arrived at the Davis home, where he could see Davis reading through the window blinds. Rader waited until the lights had been out for a few minutes, then threw a cinder block through the sliding glass door. Davis ran out of her bedroom yelling. Rader used his wanted man ruse on her. He said he would tie her up and leave her, but take her car and some food after taking some time to warm up. Davis refused and told him to leave, at which point Rader informed her that he had a gun, a club, and a knife on his person. Davis then became cooperative.<ref name="Siegel2012" /> Rader obtained the keys to her car and rattled around in the kitchen pretending to look for food. While being tied with the pantyhose, Rader believed that Davis realized that he was going to kill her. Davis begged for her life, prompting Rader to strangle her with the panty hose. Rader initially was going to stay and take photos with the body, but Davis had lied to him and said that somebody was coming soon, forcing him to leave ahead of time.<ref name="Singular2007" />

Rader used a bedspread to drag Davis's body to her car and put her in the trunk. Rader drove her car to the Kansas Department of Transportation (KDOT) lake, where he dumped her body in the bushes. Rader drove back to Davis's home and threw her keys on the roof, having read that the police had looked for the Otero's keys on the roof of their home. Rader walked back to the Baptist Church to pick up his car. Rader drove back to the KDOT, collected the body, and drove out to a rural area, where he dumped the body underneath a bridge. Rader did not take any pictures the night of the murder because he needed to get back to camp before his absence was noticed.<ref name="Paulson2018">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Davis was discovered on February 1, 1991, by a 15-year-old boy, Nelson Schock. Schock's dog went under the bridge and the boy followed when he was unable to call it back up to the street.<ref name="Geberth2010">Template:Cite book</ref>

Suspected murdersEdit

On August 23, 2023, the Associated Press reported that Rader was considered the prime suspect in two further killings in Oklahoma and Missouri. Authorities discovered "possible trophies" from victims after launching a search for evidence at Rader's former Park City home, resulting in the investigation of his potential involvement in additional unsolved disappearances and murders:<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Cynthia Dawn Kinney (16) was last seen in Osage, Oklahoma, on June 23, 1976, at Osage Laundromat.<ref>{{#invoke:citation/CS1|citation

|CitationClass=web }}</ref> Witnesses said she left the laundromat at 9:30 a.m. and got into a faded beige 1965 Plymouth Belvedere.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In 2023, Osage Sheriff Eddie Virden claimed that Rader had been identified as a prime suspect after it was determined that he was involved in Boy Scout events in the area and when it was learned that Rader had included the phrase "bad wash day" in his writings. A bank was also having new ADT alarms installed across the street from the laundromat, when Kinney went missing; Rader was a regional installer for ADT at the time. Furthermore, Rader has allegedly claimed to have "fantasized about kidnapping a girl from a laundromat."<ref name="CNNAugust2023">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Rader has denied involvement in the murder, which Virden believes is due to possibly being tried in Oklahoma and potentially being given the death penalty.<ref>Template:Cite news</ref>

Cold caseEdit

By 2004, the investigation of the BTK killer was considered a cold case.<ref>Template:Cite news</ref> However, Rader initiated a series of 11 communications to local media, which led directly to his arrest in February 2005. In March 2004, The Wichita Eagle received a letter from someone using the name "Bill Thomas Killman" claiming that he had murdered Vicki Wegerle in 1986. Enclosed with the message were photographs of the crime scene and a photocopy of Wegerle's driver's license, which had been stolen at the time of the crime.<ref name="AndersonCooper360-2006"/><ref name="vic">Template:Cite news</ref> Prior to this message, it had not been definitively established that Wegerle was killed by BTK.<ref name="vic" /> DNA collected from under her fingernails provided police with previously unknown evidence. They began DNA testing hundreds of men in an effort to find the killer.<ref>Template:Cite news</ref> Altogether, more than 1,300 DNA samples were taken and later destroyed by court order.<ref>Template:Cite news</ref>

In May 2004, KAKE received a letter with chapter headings for the "BTK Story", fake IDs and a word puzzle.<ref name="media.kansas.com" /> On June 9, a package was found taped to a stop sign at the corner of First and Kansas roads in Wichita, which contained graphic descriptions of the Otero murders and a sketch labeled "The Sexual Thrill Is My Bill."<ref name="Singular2007">Template:Cite book</ref> Also enclosed was a chapter list for a proposed book titled The BTK Story, which mimicked a story written in 1999 by Court TV crime writer David Lohr. Chapter One was titled "A Serial Killer Is Born." In July, a package dropped into the return slot at a public library contained more bizarre material, including the claim that BTK was responsible for the death of 19-year-old Jake Allen in Argonia, Kansas, earlier that month. This claim was false, and that death was ruled a suicide.<ref name="31 Years">Template:Cite news</ref>

After his capture, Rader admitted in his interrogation that he had been planning to kill again, that he had set a date (October 2004) and was stalking his intended victim.<ref name="a&e" /> That month, a manila envelope was dropped into a UPS box in Wichita. It contained many cards with images of terror and bondage of children pasted on them, a poem threatening the life of lead investigator Lieutenant Ken Landwehr and a false autobiography with many details about Rader's life. These details were later released to the public.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In December 2004, Wichita police received another package from the killer.<ref>Template:Cite book</ref> This time, the package was found in Wichita's Murdock Park. It contained the driver's license of Nancy Fox, which was noted as stolen from the crime scene, as well as a doll that was symbolically bound at the hands and feet with a plastic bag tied over its head.<ref name="31 Years" />

In January 2005, Rader attempted to leave a cereal box in the bed of a pickup truck at a Home Depot in Wichita, but the box was discarded by the truck's owner.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It was later retrieved from the trash after Rader asked what had become of it in a later message. Surveillance tape of the parking lot from that date revealed a distant figure driving a black Jeep Cherokee leaving the box in the pickup. In February 2005, more postcards were sent to KAKE, and another cereal box left at a rural location was found to contain another bound doll.<ref>Template:Cite news</ref>

In his letters to police, Rader asked if his writings, if put on a floppy disk, could be traced or not. The police answered his question in a newspaper ad posted in the Eagle, saying it would be safe to use the disk. On February 16, 2005, Rader sent a purple 1.44-megabyte Memorex floppy disk to Wichita station KSAS-TV.<ref name="probe" /><ref name="campnovel" /> Also enclosed were a letter, a gold-colored necklace with a large medallion and a photocopy of the cover of Rules of Prey, a 1989 novel by John Sandford about a serial killer.<ref name="campnovel">Template:Cite news</ref> Police found metadata embedded in a deleted Microsoft Word document that was, unknown to Rader, still stored on the floppy disk.<ref>Template:Cite book</ref> The metadata contained the words "Christ Lutheran Church" and the document was marked as last modified by "Dennis."<ref name="trutv">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> An Internet search determined that a "Dennis Rader" was president of the church council.<ref name="probe">Template:Cite news</ref> When investigators drove by Rader's house, a black Jeep Cherokee was parked outside.<ref name="Eagle20070314">Template:Cite news</ref> This was strong circumstantial evidence against Rader, but they needed more direct evidence to detain him.<ref>Template:Cite news</ref>

Police obtained a warrant to test a pap smear taken from Rader's daughter at the Kansas State University medical clinic. DNA tests showed a "familial match" between the pap smear and the sample from Wegerle's fingernails; this indicated that the killer was closely related to Rader's daughter and, combined with the other evidence, was enough for police to arrest Rader.<ref>Template:Cite news</ref>

ArrestEdit

Template:Sister project

Rader was arrested while driving near his home in Park City shortly after noon on February 25, 2005.<ref>Template:Cite book</ref> An officer asked, "Mr. Rader, do you know why you're going downtown?" Rader replied, "Oh, I have suspicions why."<ref>Template:Cite news</ref><ref name="fox">Template:Cite book</ref>

Officers from the Wichita Police, Kansas Bureau of Investigation, and FBI and ATF searched Rader's home and vehicle, seizing evidence including computer equipment, a pair of black pantyhose retrieved from a shed and a cylindrical container. Christ Lutheran Church, Rader's office and the main branch of the Park City library were also searched.<ref name="Bardsley" />

At a press conference the next morning, Wichita Police Chief Norman Williams announced, "The bottom line: BTK is arrested."<ref name="cnn">Template:Cite news</ref><ref>Template:Cite news</ref>

Rader asked about the death penalty, and inquired several times about what his potential sentence would end up being. Rader further asked whether he would be assigned to a "special section" of prison or among the "loonies" in the general population.<ref name="confession" />

Legal proceedingsEdit

On February 28, 2005, Rader was charged with 10 counts of first degree murder.<ref name="charges">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Soon afterward, the Associated Press cited an anonymous source alleging that Rader had confessed to other murders in addition to those with which he had been connected.<ref>Template:Cite news</ref> However, the Sedgwick County district attorney denied the story, yet refused to say whether Rader had made any confessions or if investigators were looking into his possible involvement in more unsolved killings.<ref>Template:Cite news</ref> On March 5, news sources claimed to have verified by multiple sources that Rader had confessed to the 10 murders he was charged with, but no other ones.<ref>Template:Cite news</ref>

On March 1, Rader's bail was set at US$10 million, and a public defender was appointed to represent him.<ref>Template:Cite news</ref> On May 3, the judge entered not guilty pleas on Rader's behalf, as Rader did not speak at his arraignment;<ref>Template:Cite news</ref> however, on June 27, the scheduled trial date, Rader changed his plea to guilty. He described the murders in detail to the court and made no apologies.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite news</ref><ref>Template:Cite news</ref><ref>Template:Cite news</ref>

At Rader's August 18 sentencing, victims' families made statements, after which Rader apologized in a rambling 30-minute monologue<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> that the prosecutor likened to an Academy Awards acceptance speech.<ref name="who" /> His statement has been described as an example of an often-observed phenomenon among psychopaths: their inability to understand the emotional content of language.<ref>Template:Cite book</ref> Rader was sentenced to 10 consecutive life sentences, with a minimum of 175 years.<ref>Template:Cite news</ref> Kansas did not enforce the death penalty at the time of the murders.<ref name="who">Template:Cite news</ref> On August 19, Rader was moved to the El Dorado Correctional Facility.<ref name="kdoc0083707">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Further investigationsEdit

Following Rader's arrest, police in Wichita and several surrounding cities looked into unsolved cases with the cooperation of the state police and the FBI. They particularly focused on cases after 1994, when the death penalty was reinstated in Kansas. Police in surrounding states also investigated cold cases that fit Rader's pattern. After exhaustive investigations, none of these agencies discovered any further murders attributable to Rader, supporting early suspicions that he would have taken responsibility for any additional murders that he had committed. As a result, the ten known murders were at that point believed to be the only murders for which Rader was actually responsible, although Wichita police are fairly certain that he stalked and researched a number of other potential victims. This includes one person who was saved when Rader called off his planned attack upon his arrival near the target's home due to the presence of construction and road crews nearby. Rader stated in his police interview that "there are a lot of lucky people", meaning that he had thought about and developed various levels of murder plans for other victims.<ref name="InsideStory" />

Psychological evaluationEdit

Massachusetts psychologist Robert Mendoza was hired by Rader's public defenders to conduct a psychological evaluation and determine if an insanity-based defense might be viable. He conducted an interview after Rader had pleaded guilty on June 27, 2005. Mendoza diagnosed Rader with narcissistic, obsessive-compulsive and antisocial personality disorders: he observed that Rader has a grandiose sense of self, a belief that he is "special" and therefore entitled to special treatment; a pathological need for attention and admiration; a preoccupation with maintaining rigid order and structure; and a complete lack of empathy.<ref>Ramsland, pp. 217–218.</ref>

The videotape of Mendoza's interview ended up being used on NBC's Dateline. NBC claimed Rader knew the interview might be televised, but this was false according to the Sedgwick County Sheriff's Office. Rader mentioned the interview during his sentencing statement. On October 25, 2005, the Kansas attorney general filed a petition to sue Mendoza and Tali Waters, co-owners of Cambridge Forensic Consultants LLC, for breach of contract, claiming that they intended to benefit financially from the use of information obtained through involvement in Rader's defense. On May 10, 2007, Mendoza settled the case for US$30,000 with no admission of wrongdoing.<ref>Template:Cite news</ref>

AftermathEdit

In 2019, Rader's daughter, Kerri Rawson, published her book A Serial Killer's Daughter: My Story of Faith, Love, and Overcoming where she goes over her childhood and Rader's role.

Imprisonment

Rader talked about innocuous topics such as the weather during the forty-minute drive to El Dorado but began to cry when the victims' families' statements from the court proceedings came on the radio. He is now in solitary confinement for his protection. This will likely continue until his death.<ref name="SerialKillerDocumentaries2012" />

In 2006, he was granted privileges during his imprisonment, allowing him to possess a television set, listen to the radio, read books, and possess art supplies.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Rader's daughter, Kerri, visited him in 2023 and reported him as "rotting" and "unhappy" reporting that "he's lost like 7 inches and he's in a wheelchair."<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In mediaEdit

Forensic psychologist Katherine Ramsland compiled Confession of a Serial Killer from her five-year correspondence with Rader.<ref name="Ramsland">Ramsland, pg. 1</ref>
