The death of Stephen "Stippo" Rakes occurred in July while Bulger was still on trial in federal court in Boston. But prosecutors say his accused killer, William Camuti, 69, was not motivated by Rakes' role in the trial, The Boston Globe reported.
District Court Judge Barbara Pearson found Camuti, a Sudbury resident, is a danger to society. She ordered him to remain behind bars for at least 90 days.
During the hearing, a State Police investigator said Camuti tried to kill himself and then admitted he had spiked Rakes' iced coffee with potassium cyanide after the two men met at a McDonald's to discuss a business dispute.
Camuti allegedly drove around the area with Rakes' body in his car before dumping it in a wooded area in Lincoln.
Rakes, who had formerly owned a liquor store in South Boston, was dropped from the prosecution witness list in the Bulger trial on the day he died. He had reportedly been eager to describe for the jury how Bulger extorted money from him at gunpoint while his daughters watched.
Bulger, who was arrested in 2011 after years as a fugitive, was found guilty of the Rakes extortion along with a long list of other crimes.
