{{Main|Contaminated evidence}}
In [[forensic science]], evidence can become contaminated. Contamination of [[fingerprint]]s, [[hair]], [[human skin|skin]], or [[DNA]]—from [[first responder]]s or from sources not related to the ongoing investigation, such as family members or friends of the victim who are not suspects—can lead to wrongful convictions, mistrials, or dismissal of evidence.<ref name="TaupinIntro13">{{cite book |url=https://books.google.com/books?id=dw2xqTVgyPsC&pg=PA134 |title=Introduction to Forensic DNA Evidence for Criminal Justice Professionals |author=Taupin, J.M. |publisher=CRC Press |pages=134–8 |year=2013 |isbn=9781439899090 |access-date=2019-04-12 |archive-date=2020-02-08 |archive-url=https://web.archive.org/web/20200208130140/https://books.google.com/books?id=dw2xqTVgyPsC&pg=PA134 |url-status=live }}</ref><ref name="GeddesHow12">{{cite web |url=https://www.newscientist.com/article/mg21328475-000-how-dna-contamination-can-affect-court-cases/ |title=How DNA Contamination Can Affect Court Cases |author=Geddes, L. |work=New Scientist |date=11 January 2012 |access-date=11 April 2019 |archive-date=12 April 2016 |archive-url=https://web.archive.org/web/20160412235503/https://www.newscientist.com/article/mg21328475-000-how-dna-contamination-can-affect-court-cases/ |url-status=live }}</ref>
