Cold Case Files is a reality legal show/documentary on the cable channel A&E Network and a rebooted series on Netflix.

The show documents the investigation of many long-unsolved murders (referred to as "cold cases" in detectives' parlance) through the use of modern forensic science (especially recent advances in DNA techniques), and criminal psychology, in addition to recent breakthroughs in the case(s) involving previously silent witnesses.

[3] According to A&E, the show has been widely praised by law enforcement agencies, and its investigative reports are commonly used in the training of detectives.

[4] Cold Case Files first aired as a sub-series of another A&E crime documentary program, Investigative Reports, also hosted by Bill Kurtis, which ran from 1991 to 2011.

Reruns of the original 1997 series currently air on broadcast syndication in the United States, usually in lower-profile time slots, and on many RTV stations.
