John James Mulligan

Detective John Mulligan was shot and killed while working a private detail. He was shot five times in the face, execution style, as he sat in his car at a store at 972 American Legion Highway.

Two suspects were tried and convicted of first-degree murder in 1995, but one suspect had his conviction overturned in 2000 when he plea bargained for manslaughter. In February 2006, the suspect admitted his participation in the execution-style killing of Detective Mulligan. He is eligible for parole in summer 2006.

Detective Mulligan had served with the Boston Police Department for 27 years. He is survived by his two sons.
