Bulger girlfriend may plead guilty, won't testify (CBS/AP) BOSTON - Family members of people allegedly killed by James "Whitey" Bulger say his longtime girlfriend will plead guilty to helping Bulger evade capture and won't testify against him at his trial. The families' comments came after they met with prosecutors Monday to discuss the status of the case against Catherine Greig. Prosecutors said she will plead guilty to two charges in California and one in Massachusetts, according to CBS station WBZ Boston. Greig was charged with conspiracy to harbor a fugitive after she was captured with Bulger in Santa Monica, Calif., in June after 16 years on the run together. Who is Whitey Bulger? Compete coverage of Whitey Bulger on Crimesider Bulger is charged in connection with 19 murders. He is most known for leading the Winter Hill Gang with Stephen "The Rifleman" Flemmi, a largely Irish mob that ran loan-sharking, gambling and drug rackets in the Boston area. According to U.S. Attorney Donald K. Stern, Bulger and Flemmi were "responsible for a reign of intimidation and murder that spanned 25 years." It earned Bulger a spot on the FBI's "Ten Most Wanted" list. The mobster was the inspiration for Martin Scorsese's acclaimed 2006 film "The Departed," and has also been the subject of several books. Tom Donahue, whose father was allegedly killed by Bulger in 1982, says prosecutors said Greig will plead guilty Wednesday to the harboring charge as well as conspiracy and identity fraud charges. Donahue says prosecutors told the families that Greig won't testify against Bulger.
