NEW YORK CITY (AP) — A woman was shot and killed while working as a construction-site flagger in a seaside Bronx community, and her boyfriend witnessed the attack and chased the gunman down, police said Wednesday.

The shooting happened around 12:30 p.m. on City Island, a small, normally tranquil residential island in Long Island Sound. The 52-year-old woman was shot multiple times.

The 67-year-old gunman rode off on a bicycle, but the woman’s boyfriend chased after him in a car, hit him with it and beat the man, police said.

The suspected gunman is in custody in a hospital, where he was taken with body trauma.
