Confessed Killer Martorano On Stand For 3rd Day In Bulger Trial

Confessed killer John Martorano was on the witness stand for the third consecutive day Wednesday in the trial of James "Whitey" Bulger.

Martorano admits he's murdered 20 people, but he struck a deal with the government to get out of jail in exchange for testifying against Bulger. Defense attorneys Wednesday questioned the basis for Martorano's freedom and tried to prove to the jury that he cannot be trusted.

WBUR's Asma Khalid reports on the details of his testimony.
