John James Mulligan

Detective John Mulligan was shot and killed while working a secondary employment 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.

Prosecutors declined to try the second suspect a fourth time after three previous convictions were overturned.

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