Whitey Bulger

Voice recordings of accused mob boss James “Whitey” Bulger were played at his murder and racketeering trial Tuesday, showing a different side than the relatively quiet defendant that the juror has so far seen, the Boston Globe reports.

The recordings capture Bulger talking about murder, guns and funneling cash.

“Pa-pa-pa-pa-pow,” whispered Bulger, during the recorded conversation on Oct. 13, as he mimicked the sound of machine gun fire.

Bulger was referring to a tavern owner gunned down in a Dorchester phone booth in 1975.

Bulger’s jail conversation with his niece and nephew occurred through a glass partition at the Plymouth County Correctional Facility, the Boston Globe wrote.
