Rescuers were still searching a massive area for three missing people on Wednesday after a boat carrying 20 family members and friends in a memorial service capsized in the cold, fast-moving waters of San Francisco Bay near Alcatraz Island, authorities said.

US Coast Guard captain Jared S Toczko said rescuers have cumulatively scoured 950 sq nautical miles (3,260 sq km) and will continue searching until sundown on Wednesday before ending rescue efforts.
