The family of a victim of notorious mob boss Whitey Bulger expressed their satisfaction over his brutal murder in a federal prison.

Michael Donahue was shot and killed in 1982 when Bulger attacked him and another man, Brian Halloran, after they left a bar. Donahue was in the wrong place at the wrong time, as Bulger had targeted Halloran for cooperating with the FBI.

Bulger, 89, was murdered inside a West Virginia prison Tuesday morning after being recently transferred there, according to reports.

"I was overwhelmed with joy. ... Of course I hope he suffered. My family has been suffering for 36 years," said Donahue's son, Tommy, in an interview with WFXT-TV of Boston. 

"He ruined my life," said Patricia Donahue, Michael's wife.

"I want to get a bottle of champagne and pop that cork. You die the way you live. He was killing people, he was killed," she added.

The Donahue family was later awarded $6 million after it emerged that the FBI was using Bulger as an informant for years. The government later appealed the judgement, and the family never received any of the money. 

According to The Boston Globe, a convicted mob hitman is one of the suspects in Bulger's murder.
