Inside Jeffrey Dahmer’s chilling ‘zombie experiments’ where he would drill holes in skulls and pour acid in brains
TWISTED serial killer Jeffrey Dahmer drilled holes in the skulls of his victims while they were still alive and poured ACID onto their brains in a perverted attempt to make them his zombie slaves.
Dahmer's youngest victim, 14-year-old Konerak Sinthasomphone, had hydrochloric acid injected into his frontal lobe before the monster killed and dismembered him.
Between 1978 and 1991, the sadistic serial killer murdered 17 teen boys and men, many of them at his apartment in Milwaukee in the US state of Wisconsin.
He would cut most of his victims up and store body parts in his freezer as sick trophies, even eating bits of flesh to fulfil his depraved urges.
Although the crimes of the "Milwaukee Cannibal" are well-documented, some of the details of his horrific crimes are still shocking to this day.
Dahmer would lure his victims - almost all of them from ethnic minority or LGBT communities - back to his apartment, often offering to pay them in return for nude photographs.

Once there, he would drug their drinks before carrying out his evil acts.
He later told the court how once drugged, he would drill a tiny hole into some of his victims' skulls "just enough to open a passageway to the brain".
Dahmer said he would then inject their brains with hydrochloric acid to induce a "zombie-like state".
In May 1991, Dahmer was almost caught after carrying out this evil operation.

Konerak Sinthasomphone, 14, had gone back to Dahmer's apartment and been drugged.
Dahmer testified he injected diluted acid into the boy's brain after drilling a hole into his skull while he was unconscious.
He then left his apartment to visit a bar and buy more alcohol, but when he returned, the boy had come to and managed to escape onto the street.
The boy, half-naked, was talking to three neighbours who, disturbed at his state and young appearance, rang the police.
According to the , the teen was naked, bruised, bleeding and heavily under the influence of drugs when he managed to escape from Dahmer's apartment.
But when cops arrived, Dahmer convinced them that Sinthasomphone was his boyfriend and that he was just drunk.

"The story I used was he was a house guest, a friend who sometimes drinks too much and runs out in the street naked," Dahmer later testified.
He added that cops failed to spot the hole he had drilled in the boy's skull.
The women tried to tell the officers to investigate and pointed out that the boy was bleeding from his rectum, but cops ordered them to shut up.
One of the officers, Joseph Gabrish, noticed that Dahmer's apartment had a foul smell of rotting flesh when he accompanied the pair back but didn't investigate further.
After the police had left, Dahmer said he gave the boy another injection of acid into his brain, which proved fatal.
"I listened for a heartbeat right after I injected him and there was none," he testified in court. "I wasn't trying to kill him but that's what happened."
Sinthasomphone's family later sued the city of Milwaukee and three police officers, including two of whom were fired over what happened.
It later emerged Dahmer had carried out a similar twisted experiment on 19-year-old Errol Lindsey, whom he had lured back to his apartment in April 1991.
He told Inside Edition in 1993 how he drilled a hole in the teenager's skull, into which he poured hydrochloric acid to try and induce a "zombie-like" state.
But Lindsey regained consciousness, causing Dahmer to drug him further to subdue him, before strangling him and flaying his corpse with the intention of keeping his skin.
Dahmer was finally caught in July 1991, but not before he had killed four more victims.
He met his own violent demise at the hands of a fellow inmate after being jailed for life at Wisconsin's Columbia Correctional Institution in February 1992.
On November 28, 1994, Dahmer was bludgeoned to death by Christopher Scarver, who was in prison for murder.

After guards left Scarver alone with Dahmer and another convicted murderer Jesse Anderson for some 20 minutes, he beat the pair with a 20-inch metal bar he had taken from the prison gym.
His story features in Netflix's new limited series on Dahmer's crimes called Monster: The Jeffrey Dahmer Story.
