Three people were killed, four were injured and seven others are missing after a small boat overturned early Monday in the ocean off San Diego, sheriff’s officials said.

Authorities suspended the search for seven missing people, including two children, after a panga-style boat overturned near San Diego on May 5 and three people were found dead.

Crews were searching for survivors. It was not immediately clear how many people were on the boat, a small, open, outboard-powered craft.
