Prosecutors drop case against man in officer’s 1993 slaying

BOSTON (AP) - Prosecutors say they will not retry a man whose conviction in the slaying of a Boston police detective in 1993 was overturned.

Suffolk County District Attorney John Pappas told reporters Monday that his office would not pursue another case against Sean Ellis, who was accused of killing Det. John Mulligan.

Mulligan was shot five times in the face while he slept in his car while on a security detail outside a pharmacy.

Ellis was sentenced to life in prison after he was convicted in 1995 of Mulligan’s death. He was released from prison in 2015 after a judge ruled he didn’t get a fair trial.

Pappas says prosecutors don’t believe they can bring a successful case because of the amount of time that has passed since the crime.
