One person has died, two are missing, and 16 have been rescued after a 19-person pontoon boat sank near San Francisco's Alcatraz Island on July 14. San Francisco Fire Department Chief Dean Crispen said crews found the three-deck vessel nearly submerged, with its motor running and leaking fuel. Fire officials said one person received CPR. Video from the scene showed the boat mostly submerged, with debris floating nearby and several rescued passengers wrapped in blankets.
