Curt Borgwardt/Sygma/Sygma via Getty Images“Milwaukee Monster” Jeffrey Dahmer killed 17 victims and ate many of them before he was murdered in prison by a fellow inmate in 1994.

Of all the many serial killers who haunt the darkest corners of American history, Jeffrey Dahmer may remain the most terrifying to this day. Between 1978 and 1991, he not only viciously murdered 17 young men and boys in and around his native Milwaukee, but also dismembered and cannibalized some of them. So, who could be capable of such a thing — who is Jeffrey Dahmer, really?

After Dahmer’s arrest in 1991, when his crimes came to light, many asked that same question. How did a quiet boy from Wisconsin develop such an appetite for murder? Why did he kill? And what drove him to eat his victims?

From the story of his first victim to the account of his own brutal murder in 1994, this is the story of Jeffrey Dahmer, who he really was, and why he did what he did.

Who Is Jeffrey Dahmer?

Born on May 21, 1960, in Milwaukee, Wisconsin, Jeffrey Lionel Dahmer was an American serial killer who operated between 1978 and 1991. Dubbed the “Milwaukee Monster,” he murdered at least 17 boys and young men between the ages of 14 and 32, some of whom he met at nightclubs or bars.

After his arrest in 1991, Dahmer was found guilty of multiple murders and sentenced to life in prison. However, he was killed by a fellow inmate in 1994. After graduating high school there and serving in a number of locations during a brief stint in the military, Dahmer lived with his grandmother in West Allis, Wisconsin.

He committed many of his crimes in her home and at various locations around Milwaukee, where he prowled for victims. After getting out of prison in 1990, he moved into his own apartment at 924 North 25th Street in Milwaukee, where he perpetrated one of his worst crimes and where he was finally arrested in 1991.

Where Did Jeffrey Dahmer Live?

After spending their earliest years in Milwaukee, the Dahmer family moved to Doylestown, Ohio in 1966, when Jeffrey was six, then moved to nearby Bath Township shortly after.

How Many Animals Did Dahmer Kill?

Most accounts state that Dahmer only killed one animal —a tadpole he’d given to a grade-school teacher, who then gave it to a different student. AETV reports that Dahmer was so enraged about the regifting that he went to the other child’s house, poured gasoline on the tadpole, and lit it on fire.

That said, Dahmer did have a fascination with animals that were already dead. AETV additionally reports that he and his father used bleach to remove hair and tissue from dead rodents they found near their house. In addition, Dahmer once impaled the carcass of a dog he found and showed his friends the grisly sight, but the animal was already dead by that point.

What Did Dahmer’s Father Do For A Living?

What Did Lionel Dahmer Say About His Son And His Crimes?

Lionel Dahmer supported his son, even after learning about his murders.

“We’ve gotten very close since his… arrest,” he told Oprah Winfrey in 1994. “I still love my son. I’ll always stick by him — I always have.”

He wondered —like many others — why Dahmer had become a killer.

“I considered all kinds of things,” Lionel explained. “Was it environmental, genetic? Was it, perhaps, medications that were taken at the time of — you know, in [his mother’s] first trimester? Was it the effect of, you know, the popular subject now, media violence?”

His son’s death in 1994 “gravely” impacted him, but Lionel also said that he’d never thought about changing his last name.

What Happened To Jeffrey Dahmer’s Grandmother?

Jeffrey Dahmer’s grandmother, Catherine, died on December 25, 1992, at age 88. But she played an important role in her grandson’s early life.

Did Dahmer Kill His Brother, David?

No, Jeffrey Dahmer did not kill his brother, David Dahmer. But the two siblings did have a very complicated relationship.

More than six years younger than Jeffrey, David was often the subject of his brother’s jealousy and resentment. Jeffrey allegedly felt that his brother had “stolen away” some of his parents’ love and affection.

Military.com reports that Jeffrey Dahmer served in the U.S. Army between January 1979 and March 1981, during which time he trained in Texas and was stationed as a combat medic in West Germany.

Though he was considered an “average or slightly above average” soldier, Dahmer had a noticeable drinking problem that got worse as time went on. In 1981, he received an honorable discharge because his superiors decided that his drinking negatively impacted his ability to serve.

While he was stationed in Europe, Dahmer also reportedly indulged in some of his violent sexual fantasies. He allegedly raped two of his fellow soldiers, Billy Joe Capshaw and Preston Davis.

Was Jeffrey Dahmer Gay And Did He Date Anyone?

Yes, Jeffrey Dahmer was gay. Dahmer described himself as gay to a judge in 1989 (when he was found guilty of sexual assault and enticing a child for immoral purposes). Dahmer and his mother also had conversations about his “gayness.” In addition, he told a probation officer in 1991 that he’d “admitted to [him]self he is gay.”

That said, it doesn’t appear that Dahmer ever had a serious relationship. Indeed, he expressed loneliness as one of his motivations to kill.

He added: “I had these obsessive desires and thoughts about wanting to control them, to, I don’t know how to put it, possess them permanently. Not because I was angry with them, not because I hated them, but because I wanted to keep them with me. As my obsession grew, I was saving body parts such as skulls and skeletons.”

Jeffrey Dahmer was killed by a fellow prisoner named Christopher Scarver. Scarver claimed that Dahmer would taunt the other prisoners by using ketchup to recreate severed limbs with his food. In Scarver’s telling, things came to a head when they were both assigned to clean a prison gymnasium. Near a locker room, Scarver confronted Dahmer about his crimes.

“I asked him if he did those things ’cause I was fiercely disgusted,” Scarver later claimed. “He was shocked. Yes, he was… He started looking for the door pretty quick. I blocked him.”
