All the real serial killers and convicted murderers featured on Netflix's 'Mindhunter'

Kemper is the first accused murderer Special Agent Holden, who's played by Jonathan Groff, interviews on the show. While the show doesn't go into much detail, all the information presented about Kemper stays true to the real story behind the "Co-Ed Killer."

Kemper, who was six-foot-nine and weighed 280 pounds, was found guilty of 10 total counts of murder between 1964 and 1973. He confessed to killing his paternal grandparents at age 15. After being incarcerated for those murders and released at 21, Kemper continued to kill.

Kemper kidnapped and murdered six young women, all students, in the Santa Cruz area in addition to killing his mother and her friend.

His victims were killed using various methods — shooting, stabbing, or choking — but Kemper confessed to practicing necrophilia with eight of the victim's corpses after separating their heads from the body.

The show goes into Kemper's childhood and abusive mother, but leaves out a couple details from his past. He also killed two cats (one of which he dismembered) when he was a young boy, and also had two near-death experiences at the hands of one of his sisters.

Kemper is still alive and incarcerated in California.

Though "Mindhunter" goes into detail about Rissell's victims, identifying the first as a prostitute, there isn't as much about him on public record as is the case with the other killers interviewed.

According to reporting from the Washington Post, Rissell raped and killed five women over a nine month period in the fall of 1976 before he was arrested and charged. He was 18 at the time, and had already been convicted of robbery and rape once before at age 16.

Rissell was eligible for parole beginning in 1995, but is still currently imprisoned at the Pocahontas State Correctional Center in Virginia. He is 59 years old.

As "Mindhunter" reveals, Brudos developed a fetish with women's shoes at a very young age. He was incarcerated for nine months at age 17 for sexually assaulting a woman, but was released after evaluations concluded he was not psychotic.

Between 1968 and 1969, when Brudos was 28, he allegedly killed at least five women. Each of his victims were strangers, all young women, who he would bring to his private garage and assault. He dismembered several of the bodies, and dressed them in high heels or other clothing.

Brudos allegedly had sex with at least one of the corpses before disposing of it. He also amputated the breasts of two victims and made molds from the body parts to keep as trophies.

Brudos initially confessed to the murders, but recanted the confession. He was convicted for three of the murders and imprisoned at the Oregon Department of Corrections from 1969 until he died of liver cancer in 2006.

Speck is one of the later interviewees in "Mindhunter." He was a high-school dropout and alcoholic by age 15. By the time he was 24, in 1966, Speck was in Chicago looking for work. He got drunk and went to a house where eight nursing students were living. Speck forced his way in by brandishing a knife, and proceeded to systematically tie-up and kill each of the women.

A ninth woman was in the house and was bound by Speck, but she hid under a bed and Speck reportedly simply forgot to go back and kill her.

On "Mindhunter," Speck concludes his interview by aggressively telling Holden he killed the women because "it just wasn't their night."

This is a real quote from Speck, but according to The Chicago Tribune it came from a recording Speck's fellow inmates made later in his life.

Speck died of a heart attack in 1991. He was 49 years old and still incarcerated.

On both seasons of "Mindhunter," Rader is shown in a brief scene at the start of each episode. He was known as the "BTK" (which stands for "bind, torture, kill") killer.

Rader really was an ADT employee, just like the show's character. He killed 10 people over the course of 20 years while living in the Wichita area of Kansas before he was arrested and convicted in 2005.

He sent taunting letters and clues to police over the years. Rader was also obsessed with knots and bondage, and would bind his victims and then suffocate or strangle them. This was teased in the "Mindhunter" scene with him tying knots over and over while watching TV.

Rader is still alive and being held in El Dorado Correctional Facility in Kansas. He is 72 years old and his earliest possible release date is listed as 2180.

For more about Rader's scenes on "Mindhunter," read our explanation of how details of his killings were teased throughout the first season.

Berkowitz was featured on the very first episode of "Mindhunter" when agent Holden Ford sees him on the cover of Time Magazine and later listens to part of a lecture about "random" killings.

But he didn't appear as a character until the start of the second season when Ford and Tench go to interview him.

The real Berkowitz did use .44 caliber Bulldog revolver to shoot at women seated in cars and on porch steps around the New York City boroughs starting in the summer of 1976. His first murder victim was stabbed, however. Over the course of nearly a year, he killed six people and wounded another seven.

As explored on "Mindhunter," Berkowitz initially claimed to be following the orders of a demon which was possessing his neighbor's dog. He pleaded guilty to the crimes anyways and later retracted the claim of demonic influence.

Preferring the name "Junior," Pierce is a convicted serial killer who is currently still serving prison time in Georgia. While he was already being held in state prison for the death of several other people, charges were brought against Pierce for the sexual assault and murder of 13-year-old Peggy Cuttino, the daughter of South Carolina senator James Cuttino.

On "Mindhunter," the FBI investigators look at a photo of Pierce in his cell where he is surrounded by junk food. That is a real image, captured in 1971 at the Appling County Jail in Georgia.

The original caption for the photo read: "William Joseph Pierce, Jr., charged with six counts of murder, poses in his cell here at the Appling County Jail. Items on right are some of the personal items he is permitted to keep in the cell."

The image shown on "Mindhunter" had actor Michael Filipowich's face digitally placed over the real Pierce's head.

Hance, a former soldier, was charged and convicted for "bludgeoning" a sex worker in 1978. He maintained his innocence until his death sentence was carried out via the electric chair in Georgia almost 20 years later.

News reports from the time corroborate the story told during the fictionalized interview on "Mindhunter" — Hance was accused of writing letters to the police he signed as "Chairman, Forces of Evil" in order to try and throw authorities off his scent.

Hance's appeal for his case made its way all the way to the US Supreme Court, where it was ultimately rejected (Justices Harry Blackmun, John Paul Stevens, and Ruth Bader Ginsburg all dissented).

As explored during his scene on "Mindhunter" season two, then-18-year-old Henley was found guilty by a jury for the murder of dozens of his peers. This series of deaths is often called the "Houston Mass Murders."

"Police said Henley, one of two defendants in the case, had procured young boys — some his friends and neighbors — for Dean A. Corll, 33, who homosexually raped and tortured them," the Argus Press reported on July 16, 1974.

The second defendant was David Owen Brooks, a 19-year-old who was charged with four counts of murder.

Henley shot and killed Corll in 1973, which was ruled by a jury as self-defense. After killing Corll, Henley called the police to confess and later accompanied authorities to the burial sites of the victims.

He is currently serving his life sentence in a Texas prison called the Mark W. Michael Unit.

Manson infamously led a cult of people referred to as the "Family," and together the group killed nine people over the course of several months in 1969. The most famous of these are the Tate-LaBianca murders, when pregnant movie star Sharon Tate and several others were brutally stabbed and killed in two subsequent nights.

Actor Damon Harriman plays Manson on "Mindhunter," and also appeared as Manson in Quentin Tarantino's recent movie "Once Upon a Time in Hollywood."

In 1969, Watson participated in the murders of Sharon Tate, Jay Sebring, Wojciech Frykowski, Abigail Folger, and Leno and Rosemary LaBianca.

Along with some of Manson's other "Family," Watson was convicted of seven counts of first-degree murder and one count of conspiracy to commit murder. His death sentence was invalidated when California outlawed the death penalty in 1971, so Watson is now still serving prison time at the Richard J. Donovan Correctional Facility in San Diego, California.

Bateson — who worked as radiologist and even appeared in 1973's "The Exorcist" during the memorable angiogram scene — stabbed and killed reporter Addison Verrill in 1979.

At the time of his conviction, police in New York City were investigating a series of unsolved murders of gay men. As mentioned during the "Mindhunter" scenes involving Bateson's case, some authorities believed he was also responsible for these serial killings but he never confessed to any murders other than Verrill's.

Bateson served just over 24 years in prison before his release in 2003. His current whereabouts are unknown.

The Atlanta Child Murders was a series of killings carried out in Georgia from 1979 to 1981. As "Mindhunter" shows in its closing minutes, Williams was only charged with two of the nearly 30 deaths being investigated at the time by local authorities and the FBI.

Williams, now 60 years old, is still serving out his sentence in prison, though he denies all involvement in the crimes and maintains his innocence.

Coincidentally, several months before the return of "Mindhunter," the current Atlanta police chief announced that new DNA technology would be used to retest evidence in the Atlanta Child Murder cases.
