The Marine amphibious assault vehicle that sank off the Southern California coast while carrying eight Marines and a Navy corpsman during a training exercise last week was found with human remains after an intensive search effort, military officials said Tuesday. 

The landing craft sank 385 feet after taking on water during a ship-to-shore maneuver off the coast of San Clemente Island on Thursday. The Marines and the sailor were heading back to their ship when the vessel sunk.
