Roy Joseph Sergei

Detective Joseph Sergei was shot and killed by a man who had just shot another officer during a subject stop.

Detective Sergei and several other officers had responded to a domestic disturbance at 371 Commonwealth Avenue. Two officers who had gone to the back of the building encountered an unrelated person attempting to climb a 12-foot fence. The officers stopped the man and as they began to pat him down he suddenly reached into his coat and fired a shot through his clothing, striking one of the officers.

The man then fled through the alley to Massachusetts Avenue where he encountered Detective Sergei at the front of the building. The man shot Detective Sergei as he continued to flee.

The man fled to Mexico but was apprehended, extradited back to Boston, and sentenced to life in prison.

Detective Sergei had served with the agency for 17 years. He is survived by his wife, three children, and parents. He was posthumously promoted to the rank of Detective.
