Jeffrey Dahmer was beaten to death inside a Wisconsin prison back in November of 1994 by a fellow inmate. Now that inmate is speaking publicly for the first time–explaining why he killed the ‘Milwaukee Cannibal.’

According to a report from CNN, Christopher Scarver is serving two life sentences–one for killing Jeffrey Dahmer and the second for killing another inmate–Jesse Anderson. Scarver was initially sentenced to life in prison for the shooting death of John Feyen, a site manager at a Wisconsin Conservation Corps job program where Scarver was a trainee carpenter.

Christopher Scarver claims he killed Jeffrey Dahmer in part because of his creepy sense of humor. The New York Post reports that Scarver said Dahmer ‘would fashion severed limbs out of prison food to taunt the other inmates.’

He would then ‘drizzle on packets of ketchup as blood.’

“He would put them in places where people would be,” Scarver explained.

Christopher Scarver kept a newspaper article in his pocket–one that detailed how Jeffrey Dahmer killed, dismembered–and in several cases even ate–17 men and boys from 1978 to 1991.

He was doing a bathroom cleaning detail along with Jeffrey Dahmer and Jesse Anderson one day, when someone poked him in the back.

“I turned around, and [Dahmer] and Jesse were kind of laughing under their breath,” Scarver said. “I looked right into their eyes, and I couldn’t tell which had done it.”

Shortly thereafter, the three inmates split up. Scarver then followed Jeffrey Dahmer to a staff locker room. He grabbed a metal bar from the weight room and confronted Dahmer–showing him the newspaper clipping from his pocket.

“I asked him if he did those things ’cause I was fiercely disgusted. He was shocked. Yes, he was,” Scarver said.

“He started looking for the door pretty quick. I blocked him,” Scarver said.

Christopher Scarver then proceeded to crush Jeffrey Dahmer’s skull with two blows with the bar.

“He ended up dead. I put his head down,” he said.

Scarver then approached Jesse Anderson in a nearby locker room.

“He stopped for a second and looked around. He was looking to see if any officials were there. There were none. Pretty much the same thing [happened]–got his head put out,” Scarver said of Anderson.

Jesse Anderson was serving a life sentence for killing his wife in 1992.

Christopher Scarver has been diagnosed with schizophrenia. It’s uncertain if he was delusional when he beat Jeffrey Dahmer to death.

It’s interesting–and disgusting–to learn that Jeffrey Dahmer never lost his penchant for cannibalism–even after being sentenced to life in prison.

Word of his murder back in 1994 didn’t exactly shock those familiar with his gruesome case.
