Three people are dead after a "panga" boat washed ashore Monday morning in southern California. Based on survivors' reports, the craft seems to have been a vessel used for migrant travel.

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.

U.S. Coast Guard vessels and helicopters were searching for the missing while the four injured were sent to hospitals, authorities said.
