Forensic Files, originally known asMedical Detectives, is an Americandocumentary television program that reveals howforensic science is used to solveviolent crimes, mysterious accidents, and outbreaks of illness. The show was originally broadcast onTLC. It is narrated byPeter Thomas, produced byMedstar Television, and distributed byFilmRise, in association with truTV Original Productions. It broadcast406 episodes from its debut on TLC in 1996 until its final episode in 2011. Reruns shown onHLN were initially retitledMystery Detectives before settling on the main title of the show in 2014.

A version of the program was broadcast onFive in the United Kingdom, under the nameMurder Detectives. Most of the 400 episodes are also available on the "FilmRise True Crime" channel that is managed by distributorFilmRise.^[1]

On October 1, 2019, HLN announced it had greenlit a revival of the show, titledForensic Files II, which began airing on February 23, 2020.^[2] Due to long-time narrator Peter Thomas' death, the show is narrated byBill Camp.^[3][4]

The show helped pioneer documentary-style crime-science shows. Its website says it profiles "puzzling, often baffling cases whose riddles are ultimately solved by forensic detection." The cases and people are real. Scientists and forensic experts in many fields are interviewed.

Not every case is a crime. In some cases, the investigation reveals that the suspects are innocent, and that a death was an accident or suicide. Several episodes profile people who have been jailed for or convicted of a crime and ultimately exonerated by forensic evidence. Other episodes focus on accidents where consulted experts relied on forensic evidence to explain why the incident occurred, such as the 1987King's Cross fire and the1993 Big Bayou Canot train wreck. Many of the accident investigation episodes were originally broadcast as a separateCourtTV program,Extreme Evidence, but are now rerun under theForensic Files name and included in theMystery Detectives rebranding.

AlthoughMedical Detectives also showed episodes about how outbreaks of mysterious illnesses were tracked (such asHantavirus andLegionellosis), most of them have been dropped in favor of episodes about criminal cases (and occasionally civil cases).

Not every episode ofForensic Files was narrated byPeter Thomas, a well-knownvoice-over talent. Four special hour-long episodes ("Payback", "Eight Men Out", "See No Evil", and "The Buddhist Monk Murders") were narrated by Peter Dean due to a scheduling conflict.^[5] These episodes were originally broadcast on TLC in 2001 and all except for one ("Eight Men Out") aired for the first time on the HLN Network in 2016.^{[citation needed]}

Each episode includes interviews with witnesses, investigators, and forensic scientists. Many of the world's foremost forensic analysts have appeared on the show (often in more than one episode), includingHenry Lee,Cyril Wecht,William M. Bass,Alec Jeffreys,Skip Palenik, and Richard Souviron.^{[citation needed]}

For the dramatic recreations, lookalike actors and models resembling the main figures in the story were found through a casting company inAllentown, Pennsylvania,^[6] or through open casting calls in New York and other cities.

The program began on theTLC Network in April 1996 asMedical Detectives.^[7] Old episodes ofMedical Detectives now air on TruTV under theForensic Files label. Overseas, the show airs under these two titles, and others, on various channels in over 100 countries. It is distributed by CABLEready.

For the first four seasons under theMedical Detectives name, the format of the show was generally the same as it would be in later seasons under its "Forensic Files" name, but there were slight differences. During the opening credits and after the title display of the show, the titles of the episodes appeared and they were each displayed distinctively. For example, "The Disappearance of Helle Crafts" depicted a jigsaw puzzle coming together that displayed a picture of Helle Crafts and this picture lead into the episode (under theForensic Files name, this picture was replaced with another), and "Raw Terror" depicted the words in big red letters against a black screen. The titles were sometimes featured in a visual representation to accommodate the subject at hand. For example, "The Southside Strangler" depicted black and white buildings coming down the screen; the buildings were displayed there in order to represent the "southside" of wherever the crime happened in and Season 2's "The Common Thread" displayed the title through a use of small "thread" strands that dangled in full-view and formed the title. The re-enactment scenes for the first couple of seasons were displayed in black and white and an eerie music score with a tunnel-like echo voice was used in order to provide a more terrifying feel to the show.

When CourtTV acquired the rights to the show for its fifth season, the decision was made to rename the showForensic Files in order to emphasize the forensic science that was performed on the cases and connect it better with other documentary/reenactment crime shows with a similar title such asThe FBI Files andCold Case Files. A new opening was produced for Seasons 5 and 6 (and a couple in Season 7) and it depicted footage from the first four seasons. The title display "Forensic Files" is depicted in big blue and red letters with a background light beaming across the "Forensic" part. This opening was later used for theMedical Detectives episodes, removing their original openings and distinctive title displays. 6 episodes (The Footpath Murders,Raw Terror,Deadly Neighborhoods,Sealed with a Kiss,Deadly Parasites, andForeign Body) were never incorporated under the Forensic Files name due to CourtTV's desire to have the show focus on crime-related episodes instead of disease outbreaks or medical mysteries. Several others were also not brought over due to featuring extremely graphic crime scene photos. These episodes are unavailable on streaming or DVD, and can be seen via secondary copies online only under its original format when they were aired asMedical Detectives.

In Season 7, a new opening sequence was made with an entirely new theme song, providing a more tech-based feel and featuring a new title format. The titles of the episodes are quickly scanned underneath the title displays. No footage from actual episodes is used and everything displayed was made exclusively for the opening. This opening was used on a number of rebrandedMedical Detectives episodes; replacing the opening for Seasons 5 and 6 that was originally given to them. Episodes such as "The Southside Strangler" and "Legionnaires' Disease" can be seen with all three openings. Season 7's "Reel Danger" can be seen with two.

By Season 12, starting with the twentieth episode, the opening sequence was shortened entirely and as a result, just the title of the show is featured and the title of the episode displayed beneath it. The episodes from here on out now had a faster-paced opening preview of the episode with upbeat music and Peter Thomas starting off saying "Up Next...".

On October 1, 2019, HLN announced it had acquired the broadcasting rights from Medstar Television to produce a revival of the series, with the first season consisting of 16 half-hour episodes. The new show is titledForensic Files II,^[2] and the first episode is scheduled to air on February 23, 2020, withBill Camp serving as the new narrator.^[3]

The show takes a "whodunit" approach, making each case a mystery that needs to be solved. Every half-hour episode follows one case from its initial investigation until the suspect(s) conviction, acquittal, or some other legal resolution. Pathologists, medical examiners, police officers, detectives, prosecutors, defense attorneys, friends and families of victims or suspects (if their cooperation is given) are all interviewed about their roles.

Video footage of the lab tests is shot in a modernisticfilm noir style, in dark, moodily lit settings with odd, glowing colors. The crimes and parts of the investigation are re-enacted with actors in dramatic recreations. These recreations are indicated by a change to a "filmized" look, as is done with many crime re-enactment shows.^[8] These recreations sometimes include alternate versions of the crime, which are eventually disproven by the science. This technique would later be appropriated, in a modified form, by the CBS television seriesCSI: Crime Scene Investigation—essentially a fictionalized big-budget version ofForensic Files. During the original run of the show asMedical Detectives, eerie vocal music was matched with the recreations in order to create a frightening atmosphere. This specific effect was discontinued after the move to Court TV.

For privacy considerations, the names of some victims and their families are changed, and case evidence featured within the show is re-created in order to protect their true identities. That is unless consent is given by the persons who are being spoken to, the show is not allowed to use the family's (or families') real name(s).

In 2006,Forensic Files "Advanced" episodes aired, which had older episodes interspersed withPop-Up Video style factoids about the cases which were then being featured.

Sometimes, another case is mentioned which is similar to the one being aired. For example: "Cold Hearted" on "Freeze Framed" and "Past Lives" on "A Squire's Riches". In another episode that involves DNA evidence, the name of a man shown on an older episode was mentioned again and this time he was revealed to have been the first person put to death in the United States based on DNA evidence.

On re-runs of episodes on HLN, an update of the case is given on the criminals that were alive at the time the episodes were aired (deaths, paroles, releases, etc.).

Premiering just as theO. J. Simpson murder trial had focused attention on the world ofDNA andforensics,Medical Detectives became a hit.^[9] It was one of the first of the popular forensic science shows. A few years later, Court TV acquired rights to broadcast the show and it quickly became the cornerstone of its primetime schedule, increasing its annual production run to 42 episodes. The show was retained after the network was renamed TruTV in 2008.

The show was so successful that, in 2002,NBC aired it as a summer replacement series, one of the first times in which a program produced for cable television was aired by a broadcast network inprime-time.^[8][10]

In 2009, truTV's sister networkTurner Network Television ("TNT") began airing episodes inHD on Wednesday nights for the month of December.^[11]

The vast majority of the shows are in a half-hour format. However, some hour-long specials have been produced. Several of these have re-investigated famous cases such asThe Norfolk Four, or even historic murders such as theLindbergh kidnapping and theJohn F. Kennedy assassination.^[12]

Reruns were aired onLifetime in the fall of 2011 under theMedical Detectives moniker.^[13] A year later, in October 2012,HLN began airing the reruns under the titleMystery Detectives. Beginning in January 2014, HLN switched to the "Forensic Files" title.^[14] On that network, it is increasingly being used to fill many time slots due to program cancellations by budget cuts. By 2016, the program took up about 58% of the entire HLN channel each week.^[15] In June 2014, the program aired nightly from 2am through 5am onCNN, before being removed due to industry and viewer criticism,^[16] along with continuing international breaking news events, and replaced with aCNN International simulcast. Since November 7, 2015, HLN has retitled the program "Forensic Files: Digital Details" and aired episodes that did not air on the channel before. The show led HLN in ratings in early 2015.^[17]

TruTV currently still holds the licensing rights to the Forensic Files name.^[18] The reruns were repackaged with a shorter intro, and (at the end of some episodes) updates on what became of the suspect(s) or parties involved since the final verdicts. (For example: At the end of the 1996 episode "The List Murders", it is mentioned thatJohn List, convicted of murdering his entire family in 1971 and sentenced to life in prison, died in 2008.) In late 2014,Investigation Discovery started airing episodes under the "Cause of Death" title.^[19] Reruns of the show also were formerly carried over-the-air onCourt TV, sister channelIon Mystery, AMGTV and currently onTrue Crime Network and in off-networksyndication. As of 2022 the entire catalog of Forensic Files is available onPeacock, while a "Best of Forensic Files" series is available on Amazon Prime. It also currently has its own channel onPluto TV.

HLN advertised "brand new episodes ofForensic Files" intermittently since 2014, when the advertised "new" episodes are actually just old episodes that had never aired on the network before and were new to HLN.^[20] The advertisement of these episodes caused confusion, with some viewers taking toTwitter to ask the show's creator, Paul Dowling, if the show was going back into production. The show's narrator,Peter Thomas, died on April 30, 2016, five years after the program went out of production. Dowling stated that Thomas "can't be replaced," thus eliminating any hopes of reviving the program.^[21] Despite this, the program was revived for an additional season for February 2020.^[2]Bill Camp was chosen to succeed Thomas as the show's narrator.^[22]

In 2004,Court TV released a limited number of episodes on DVD. As of June 26, 2009, Amazon.com says the DVD has been discontinued by the manufacturer.^{[citation needed]}

In August 2011, TGG Direct released 8 DVD collections each containing 12 episodes. These collections include "Historic Cases", "Convictions Overturned", "Death By Poison", "Crimes of Passion", "Kidnapping Cases", "Medical Mysteries", "Serial Killers" and "Sex Crimes".^{[citation needed]}

As of February 2020,Netflix in the U.S. is streaming most of the 406 episodes, split into 9 collections; seasons 7–9 and 11–14 are also available onHulu. The latter also planned to streamForensic Files II on its premium subscription service.^[23]

This basic cable offering has been reviewed infrequently by television critics. In August 2002, TheHouston Chronicle compared it to an episode ofUnsolved Mysteries: "A criminal story is told – the more bizarre the better; a mysterious element is introduced; and forensic experts solve the mystery. All that's missing isRobert Stack."^[24]

TheLos Angeles Times gave this review in April 2001: "AlthoughForensic Files ably extends this specialized field to the masses and deploys its slick reenactments effectively, its jarring voice-over is the overcooked antithesis of the meticulous science it depicts."^[25]

The new series, which had recently premiered its second season on July 11, 2021, uses the same formula as the original, though with a new narrator, Bill Camp. "We are telling the same kinds of stories in the same way," Executive Producer Nancy Duffy said in an interview. Instead of hiring actors to play the fictional roles, however, the new series uses "employees ofCNN andHLN".^[26][27]

Forensic Files II began airing on February 23, 2020.

The Official Forensic Files Casebook was published in 2004. The book recaps and expounds on some episodes, explains how the show is produced, and details why some proposed episodes were turned down. In it, the show's Executive Producer/Writer Paul Dowling says he was inspired to create the show because he had been present in Philadelphia during the outbreak ofLegionellosis in 1976, as well as by the murder ofHelle Crafts. TheCDC's legionellosis investigation eventually became an episode ofMedical Detectives, while the Crafts case was filmed as the program's pilot episode.^[9]

In January 2020, Forensic Files Podcast debuted and featured audio from a selection of theForensic Files airings.^[28]
