Editing CSI: Crime Scene Investigation (section)

==Premise==
Mixing deduction and character-driven drama, ''CSI: Crime Scene Investigation'' follows a team of crime scene investigators (CSIs) employed by the [[Las Vegas Metropolitan Police Department]] (LVPD for short) as they use physical evidence to solve murders.

The team is originally led by [[Gil Grissom|Dr. Gil Grissom]] (William Petersen), a socially awkward forensic entomologist and career criminalist, who is promoted to CSI supervisor following the death of a trainee investigator. Grissom's second-in-command, [[Catherine Willows]] (Marg Helgenberger), is a single mother with a cop's instinct. Born and raised in Las Vegas, Catherine was a stripper before being recruited into law enforcement and trained as a blood-spatter specialist.

Following Grissom's departure during the ninth season of the series, Catherine was promoted to supervisor. After overseeing the training of new investigator [[Raymond Langston]] ([[Laurence Fishburne|Lawrence Fishburne]]), Willows is replaced by [[D.B. Russell]] ([[Ted Danson]]) and recruited to the FBI shortly thereafter. Russell is a family man, a keen forensic botanist, and a veteran of the Seattle Crime Lab.

In the series' 12th season, Russell is reunited with his former partner [[Julie Finlay]] (Elisabeth Shue), who like Catherine, is a blood-spatter expert with an extensive knowledge of criminal psychology. With the rest of the team, they work to tackle Las Vegas's growing crime rate and are on the job 24/7, scouring the scene, collecting the evidence, and finding the missing pieces that help solve the mystery.
