This documentary is sure to make you question all those seemingly casual and normal people whom you come across every day. This serial killer documentary by Chris James Thomson is based on the murders and horrific crimes committed by Jeffrey Dahmer between 1978 and 1991.

Dahmer was a notorious serial killer with a casual demeanour and without any real motive. He killed 17 boys and men and was accused of raping and mutilating them before his arrest in Wisconsin in 1991. The documentary uses real archival footage of his trial sessions as well as interviews with the case’s lead detective Patrick Kennedy, medical examiner Jeffrey Jentzen and one of his neighbours Pamela Bass who shared detailed accounts of his life and personality.

The film’s format is also interesting. Instead of just stating facts and producing the footage, it shows certain segments of his crimes in a dramatic way. The Jeffrey Dahmer Files was initially released as Jeff at the 2012 SXSW Film festival but was later changed to its current name after being taken up by IFC Midnight.

In 1983, when innumerable people were flocking to the World’s Fair, this dreaded serial killer was hatching quite a sinister plan. This John Borowski documentary explores one of American history’s most famous serial killers — H.H. Holmes, who chose his victims from the fair.

Holmes, also known as ‘Torture Doctor,’ was a mastermind who went to the length of building a full-fledged hotel in Chicago, with torture chambers, trap doors and acid tanks, where he tormented his victims before killing them. Infamously called the ‘Murder Castle’ this hotel was a complete maze and though its claims were proven false, it gave rise to a number of films and series including the season titled Hotel of the American Horror Story (2010).

Interestingly, though Holmes himself confessed to 27 murders, he was sentenced to death for just one — his associate and business partner Benjamin Pitezel.

One of the most gruesome serial killer documentaries, H.H. Holmes: America’s First Serial Killer is sure to leave you with sleepless nights, owing to its dramatic reenactments which bring his crimes alive on screen.

A sequel to his 1992 documentary, Aileen Wuornos: The Selling of a Serial Killer, Nick Broomfield’s 2003 true crime documentary takes viewers to the final days of the female serial killer who was on death row for nearly 12 years.

The film revolves around Aileen Wuornos’ degrading mental health and her fading from reality. Wuornos was a sex worker and was accused of killing six to seven men between 1989 and 1990. These men were reportedly her clients who had allegedly assaulted and tried to rape her. According to the accused herself, these murders were committed in self-defence and the film also upholds this argument.

Aileen was executed in 2002 via lethal injection and the film strongly advocates her cause and hints at a grave misjudgment being meted out. It believes that since she was not in the correct frame of mind, she should’ve been admitted to a mental health institute for treatment.

Along with her interviews in prison and footage from court trials, this true crime serial killer documentary poses questions about humanity and mental health.

A New York urban legend of a boogeyman — ‘Cropsey’ — inspired filmmakers Joshua Zeman and Barbara Brancaccio to delve deep for more details about the missing cases of five children from Staten Island.

The director duo brought out the gruesome case of child abductor and alleged serial killer Andre Rand whose heinous and terrifying crimes made the legend real. The documentary does a detailed study of all the cases of the missing children and attempts to answer some unanswered questions to the families residing in the area about what had happened.

Rand was a patient at Staten Island’s Willowbrook Mental Institute and was allegedly involved in Satanism. While the urban legend of Cropsey was made to keep children away from the remnants of the dilapidated building, this serial killer documentary takes viewers through its ruins giving an almost horror film-like eerie vibe.

Undoubtedly one of the best serial killer documentaries and another Nick Broomfield gem, Tales of the Grim Sleeper was shot with the director’s son Barney Broomfield and Marc Hoeferlin on board as well.

This true crime documentary depicts the gruesome crimes of Los Angeles-based serial killer Lonnie David Franklin Jr. who was on a raging murder spree between 1984 and 2007. The reason Franklin got the nickname ‘the grim sleeper’ was because he took a sort of sabbatical from killing between 1988 and 2002.

This documentary deals with 10 of his murders before he was brought to justice. Though Franklin was accused of nearly 100 deaths, these killings — nine women and a teenage girl — gave him the death sentence.

Instead of going behind the mind and motive of the serial killer, the documentary focuses on the loose investigations and the incompetency of the LAPD who let the homicide go on for nearly 25 years. It also depicts the lives of his victims and makes viewers question the system.
