SHIRLEY -- A neo-Nazi convicted killer who is serving two life sentences for murder died Monday in a suspected suicide at the Souza-Baranowksi Correctional Center in Shirley.
Keith Luke, 28, of Brockton, was pronounced dead at 12:10 p.m. at University of Massachusetts Memorial Medical Center in Worcester, Darren Duarte, spokesman for the state Department of Correction, told the Boston Herald.
The former Brockton resident, who was serving two life sentences for murder and 210 years for rape, kidnapping and other crimes, had been on life support since he was found unresponsive in his prison cell at Souza-Baranowski Correctional Center in Shirley just after 1 p.m. on Saturday, Duarte said.
Duarte told the Herald prison officials rushed Luke to Leominster Hospital and later transferred him to UMass Memorial Medical Center, where he died two days later.
State officials suspect suicide -- not foul play -- but the cause of death is still under investigation, according to Duarte.
Luke had tried to commit suicide in the past, including a 2010 attempt that landed him in the hospital for surgery after a self-inflicted throat wound, according to the Herald.
Luke was convicted last year in the racially motivated murderous rampage that began when he barged into a neighbor's home, repeatedly raping and shooting her, the Herald reports.
