California rail-yard shooting: Police release dramatic body-cam video

A gunman who killed nine co-workers at a Northern California rail yard shot himself twice in the head as sheriff's deputies raced into a building, according to authorities who on Tuesday released body-camera footage of the tense encounter.

A "contact team" of deputies and San Jose police officers were immediately formed to find the gunman, who was reported to be inside a building and armed with a handgun. The body camera footage shows the team cautiously climbing stairs to the third floor, where a VTA supervisor comes out with arms raised and hands over his keycard so officers can get inside the building. The five-member team then sweeps into the building, guns raised, using gun-mounted flashlights as they pass through rooms and corridors to a dispatch center.
