On May 21, 1960, Jeffrey Dahmer was born at Evangelical Deaconess Hospital in Milwaukee, Wisconsin.¹⁾

Jeffrey Dahmer received his high school diploma from Revere High School in May 1978. He then enrolled at Ohio State University to major in business but was dismissed after the first semester owing to his drinking problem and bad grades.²⁾

Dahmer lived in Morrill Tower, and some locals believe he is still haunting the building.³⁾

After dropping out of college, Jeffrey Dahmer joined the army. He received combat medic training at Fort Sam Houston, Texas, and was eventually dispatched to Baumholder, West Germany. He was only in the service for two years before being discharged honorably in March 1981. He was also discharged from the service due to his drunkenness.⁴⁾

Preston Davis, one of the army personnel he tormented, claimed that Dahmer would gloat about his first victim while he was inebriated.⁵⁾

Jeffrey Dahmer committed his first murder three weeks after graduating from high school. Dahmer killed Steven Hicks, an 18-year-old hitchhiker, by smashing the back of his skull with a dumbbell. Dahmer waited nearly a decade after this criminal encounter before killing his next victim.⁶⁾

David was named by Jeffrey Dahmer, his younger brother. They split up after their parents divorced in 1978. David has little to no knowledge because he officially changed his name to begin a new life. Only their father, Lionel Dahmer, revealed that David already has a job and a family.⁷⁾

Many performers inserted references to Jeffrey Dahmer in their lyrics, prompting listeners to condemn their older songs. Eminem's Bagpipes from Baghdad and Must Be the Ganja, Katy Perry's Dark Horse, and Kesha's Cannibal are a few examples.⁸⁾
