Jeffrey Dahmer

To this day, serial killer Jeffrey Dahmer remains a subject of lurid fascination in the world of true crime. Tried and convicted of 17 grisly murders that often involved acts of cannibalism and necrophilia, Dahmer's killings continue to grip the public imagination — inspiring a number of films and documentaries

Oxygen's "Dahmer on Dahmer: A Serial Killer Speaks" offers an in-depth look at the killer with exclusive interviews from those closest to him, including parents Lionel and Shari Dahmer, along with surviving victims Billy Capshaw and Preston Davis, who decided to finally break their silence about what happened to them — all adding up to a chilling portrait of the cannibal killer.

Ted Bundy

One of the most notorious serial killers in history, the story of Ted Bundy's horrifying crime spree was reignited in 2019, when Zac Efron portrayed the charming murderer in the biopic “Extremely Wicked, Shockingly Evil and Vile.” 

Although Bundy killed at least 30 women, he went relatively unnoticed until Aug. 16, 1975, when a routine traffic stop led to the discovery of multiple suspicious items, including pantyhose, a ski mask, a crowbar, an ice pick, and handcuffs.

As Oxygen's "Snapped: Notorious Ted Bundy" explores, Bundy soon became a suspect in murders across the U.S., and his eventual trial in June 1979 was the first to ever be televised nationally in the US.

Many people undoubtedly first became aware of Ed Kemper, aka "The Co-Ed Killer", through the chilling portrayal of him on Netflix's true crime series "Mindhunter," by actor Cameron Britton. Now, viewers can get a glimpse into the terrifying mind of the real Ed Kemper through the Oxygen special "Kemper On Kemper: Inside The Mind Of A Serial Killer."

In real life, Kemper notably took part in conversations with FBI special agents John Douglas and Bob Ressler for their study on serial killers. Along with Boston College professor Ann Burgess, the team used Kemper’s admissions about his life and murders to help build a system to profile future serial killers.

Also portrayed in "Mindhunter," Dennis Rader terrorized Wichita, Kansas, for almost 20 years as the BTK serial killer, an acronym which stood for "Bind, Torture, Kill." 

Around his hometown, Rader was known as a family man and church leader, and no one suspected he was the one sending taunting letters to police and media detailing his brutal, twisted crimes.

In "Snapped: Notorious The BTK Serial Killer," viewers get an exclusive look at the crime scene photographs and Rader's disturbing bondage selfies, and hear from those who knew him best, including one co-worker who described "looking into the eyes of BTK.”

Israel Keyes may not be widely known, but viewers will come away shocked at the crimes the suspected serial murderer is accused of, as documented in "Methods of a Serial Killer."

While Keyes was initially arrested for a brazen kidnapping in 2012, he ended up confessing to 11 murders and told authorities just enough for them to take him seriously. Keyes would not see justice as he killed himself while in custody — leaving behind a chilling note for the authorities — but this documentary takes a deeper look at a little-known case that audiences are unlikely to forget.

"Mark of a Killer" examines the disturbing patterns serial killers display throughout their murderous sprees. Whether they steal from their victim upon death, leave a hint that they are a repeat offender at the scene of the crime, or use a specific method to target victims, survivors and victims' families attempt to piece together what spurred these horrific crimes. Investigators examine their trademarks as they solve the mystery and seek justice. 

Season two premieres on Thursday, April 9 at 9pm ET/PT, kicking off Oxygen's "12 Dark Days of Serial Killers" event.

Legendary Italian fashion designer Gianni Versace had it all: a successful business, mansions around the world, celebrity friends, and millions in the bank. None of that, however, could protect him from Andrew Cunanan, the serial killer who took his life along with four other victims in the spring and summer of 1997.

Cunanan's motives and connection to Versace continue to puzzle investigators to this day, and "Killing Versace: The Hunt For A Serial Killer," looks into the murderer's life and his victims, which included former lovers, millionaires, war veterans, real estate developers, and cemetery caretakers.

Branded “The Damsel of Death” and the “Highway Hooker,” Aileen Wuornos was accused of killing seven men between 1989 and 1990 while she hitchhiked around Florida.

After her arrest in 1991, Wuornos quickly gained notoriety as “America’s first female serial killer.” She ultimately confessed to the killings, claiming they were committed self-defense, but the jury unanimously convicted her on six counts of first-degree murder and sentenced her to death.

In “Snapped: Notorious Aileen Wuornos," Oxygen dives deep into the deadly sex worker’s life and examines whether she was afforded a just trial, or if the media frenzy tainted her jury.

Joseph James DeAngelo

After a decades-long manhunt, Vietnam War veteran and former police officer Joseph James DeAngelo was arrested in 2018 in connection with a string of rapes and murders across California attributed to the Golden State Killer.

At the time of his arrest, DeAngelo was living a quiet life in the suburbs, where he raised three daughters. Oxygen's "Golden State Killer: Main Suspect" offers viewers an intimate look into the life of DeAngelo through new and exclusive interviews from those who were closest to him.

In the early 1990s, health care workers were puzzled when the death rate at the Veteran Affairs Medical Center in Northampton, Massachusetts, surged.

One nurse, Kristen Gilbert, was on duty for so many of the fatalities that her co-workers jokingly nicknamed her “The Angel Of Death.” Their laughter turned to horror, however, when it was revealed the casualties were no accident and that Gilbert was a serial killer.

In "Snapped: Notorious Kristen Gilbert," Oxygen examines the killer nurse who liked the "thrill" of medical emergencies.
