• The revival, Forensic Files II, began airing on February 23, 2020, with Bill Camp as narrator following Peter Thomas' death.

Overview

The show profiles puzzling cases whose riddles are ultimately solved by forensic detection, with all cases and people being real. Scientists and forensic experts in many fields are interviewed. Not every case involves a crime; some investigations reveal that suspects are innocent and that a death was an accident or suicide. Several episodes feature people exonerated by forensic evidence. Other episodes focus on accidents, such as the 1987 King's Cross fire and the 1993 Big Bayou Canot train wreck, where experts relied on forensic evidence. Many accident investigation episodes originally aired as a separate Court TV program, Extreme Evidence, but now rerun under the Forensic Files name.

Production and title sequences

The program began on TLC in April 1996 as Medical Detectives. For the first four seasons under that name, the format was generally the same as later seasons, but with slight differences. During the opening credits, episode titles appeared distinctively; for example, 'The Disappearance of Helle Crafts' showed a jigsaw puzzle coming together, and 'Raw Terror' displayed words in big red letters against a black screen. Titles were sometimes featured in visual representations, such as black and white buildings for 'The Southside Strangler' or thread strands for 'The Common Thread'.

Re-enactment scenes in the first couple of seasons were in black and white with eerie music and a tunnel-like echo voice. When Court TV acquired the rights for the fifth season, the show was renamed Forensic Files to emphasize forensic science and connect with similar shows. A new opening for seasons 5 and 6 (and some in season 7) depicted footage from the first four seasons, with the title in big blue and red letters and a background light beaming across 'Forensic'. This opening later replaced the original openings of Medical Detectives episodes.

Show format

Each half-hour episode takes a whodunit approach, following one case from initial investigation to conviction, acquittal, or other legal resolution. Pathologists, medical examiners, police, detectives, prosecutors, defense attorneys, and friends or families of victims or suspects are interviewed. Video footage of lab tests is shot in a modernistic film noir style with dark, moody lighting and odd, glowing colors. Crimes and parts of the investigation are re-enacted with actors, indicated by a filmized look. These recreations sometimes include alternate versions of the crime that are disproven by science. For privacy, names of some victims and their families are changed, and case evidence is re-created unless consent is given. In 2006, Forensic Files 'Advanced' episodes aired with Pop-Up Video style factoids. On HLN reruns, updates on criminals alive at the time of airing are given.

Broadcast run and alternative titles

Premiering just after the O. J. Simpson murder trial focused attention on DNA and forensics, Medical Detectives became a hit. Court TV acquired rights and increased annual production to 42 episodes; the show was retained after the network became TruTV in 2008. In 2002, NBC aired it as a summer replacement series, one of the first cable programs to air on a broadcast network in prime time. In 2009, TNT aired episodes in HD on Wednesday nights for December. Reruns aired on Lifetime in fall 2011 under the Medical Detectives moniker. HLN began airing reruns in October 2012 as Mystery Detectives, switching to Forensic Files in January 2014. By 2016, the program took up about 58% of HLN's weekly schedule. Since November 7, 2015, HLN has aired episodes as 'Forensic Files: Digital Details'.
