“We believe that the letters mean that Bulger encouraged Barrett to kill the victim (LaMonica), that Bulger warned Barrett not to talk about their conversation ever again and that Bulger is encouraging Barrett to come forward because Weichel is innocent,” Ricciuti said Monday.
He said the letters were written by Bulger to a supporter of Weichel’s, but he would not identify the supporter.
David Traub, a spokesman for Norfolk District Attorney Michael Morrissey, declined to comment, saying prosecutors have not seen the documents.
Bulger, 84, fled Boston in 1994. He was captured in Santa Monica, Calif., in 2011. He is serving two life sentences after being convicted of playing a role in 11 murders and a string of other crimes in the 1970s and ‘80s.
Prosecutors have said Weichel and LaMonica had an ongoing feud. They say a teenager was unequivocal when he identified Weichel as the shooter.
