“I saw postal carriers running toward me, and I yelled to them, ‘What do you think’s going on?’ and they said, ‘Someone just got shot,’ and I said, like, ‘Who?’ and they said, ‘A policeman shot someone trying to break into a house in the middle of the block,’” said witness Anna Gigliotti.

The suspect was described as a black male between the ages of 25 and 30, standing about 6 feet 3 inches tall with a slender build and short black hair. He was wearing a gray T-shirt and black sweat pants with a white stripe down both sides.

Police said the Civilian Office of Police Accountability is investigating the incident. As per routine, the officer will be placed on administrative duties for 30 days pending the investigation.

The officer is a 19-year veteran of the force and is 46 years old.
