BOSTON (CBS/AP) — Mobster James “Whitey” Bulger‘s lawyers will be returning to federal court in Boston to give a judge a status report on preparation for his March trial.

The former leader of the Winter Hill Gang is accused of participating in 19 murders. He fled Boston in 1994 and remained one of the FBI’s most wanted fugitives until his capture in Santa Monica, Calif., last year.

Bulger’s lawyers have repeatedly complained that they won’t have enough time to prepare for trial, given that prosecutors have turned over more than 300,000 documents.

Bulger lawyer J.W. Carney Jr. has said that Bulger will testify about his claim that he was given immunity to commit crimes while he was an informant.

On Monday, the Boston Herald reported that federal prosecutors have found evidence to the contrary, which could blow a hole in the mobster’s defense. The report says that the documents show the U.S. Attorney at the time of the crimes testified to Congress that Bulger was never given immunity.

A status conference is scheduled Monday in U.S. District Court.
