BROCKTON, Mass. (AP) – A 15-year-old boy is the latest shooting victim in the city of Brockton.

Police said the teen was shot in the head late Tuesday afternoon when a friend’s gun went off. Oliver Baptiste was pronounced dead an hour later. Eighteen-year-old William Suarez was charged with manslaughter and illegal possession of a firearm.

There have been four homicides since the beginning of the year in Brockton.

The shooting occurred about an hour after Gov. Deval Patrick came to Brockton to laud local and state police for a surge of officers that had prevented any shootings since mid-February.
