Rescuers were still searching for three people missing after a boat involved in a memorial service sank in the cold, fast-moving waters of San Francisco Bay near Alcatraz Island, authorities said Wednesday. One person was pulled from the water but later died, and 16 people were rescued after the boat capsized Tuesday afternoon in what witnesses described as “rough seas,” San Francisco Fire Chief Dean Crispen said. “Apparently the vessel began to take on water and was turned over in the bay,” Crispen said at a news conference Tuesday. The vessel’s motor was still running and leaking fuel when rescuers arrived, he said. Videos from Tuesday showed rescue boats surrounding the largely submerged vessel as debris floated nearby. A dog on board also died. Lt. Mariano Elias, a fire department spokesperson, described it as a 50-foot (15-meter) pleasure craft with a cabin and upper deck named Volare, documented out of Stockton, California.
