Nearly a year after Adam Peterson attacked and killed a man in his downtown Madison home, and a month after being taken off suicide watch, the convicted killer took his own life late Saturday night by hanging himself with a sheet from his bunk bed in the Dodge Correctional Institution in Waupun, according to a news release from the state Department of Corrections.
Peterson, who would have turned 21 on Feb. 22, was diagnosed with schizophrenia and psychosis after being arrested for the killing of Joel Marino, 31, in Marino’s home on Monona Bay. Peterson had attempted suicide on Sept. 25 in the Dane County Jail while awaiting trial but was rescued by a deputy.
