Dahmer was later sentenced to a sixteenth term of life imprisonment for an additional homicide committed in Ohio in 1978.
On November 28, 1994, Dahmer was beaten to death by Christopher Scarver, a fellow inmate at the Columbia Correctional Institution in Portage, Wisconsin.

Scott Edgar Dyleski (born October 30, 1988) is an American murderer, convicted of murdering his neighbor, Pamela Vitale, the wife of prominent attorney Daniel Horowitz. He received the maximum penalty allowed by the law, life in prison without parole. As a juvenile at the time of the murder, he did not qualify for the death penalty.

In 2018, Dyleski's sentence was reduced to 25 years to life in prison, after the state of California passed Senate Bill 394, which gives juveniles tried as adults and sentenced to life without parole a chance for eventual freedom. He will be eligible for parole in 2030.

Kristen Heather Gilbert (née Strickland; born November 13, 1967) is an American serial killer and former nurse who was convicted of four murders and two attempted murders of patients admitted to the Veterans Affairs Medical Center (VAMC) in Northampton, Massachusetts. She induced cardiac arrest in patients by injecting their intravenous therapy bags with lethal doses of epinephrine, commonly known as adrenaline, which is an untraceable heart stimulant. She would then respond to the coded emergency, often resuscitating the patients herself. Prosecutors said Gilbert was on duty for about half of the 350 deaths that occurred at the hospital from when she started working there in 1989, and that the odds of this merely being a coincidence was 1 in 100 million. However, her only confirmed victims were Stanley Jagodowski, Henry Hudon, Kenneth Cutting, and Edward Skwira.
