A gunman killed one passenger and wounded multiple others on a Greyhound bus travelling from Los Angeles to the San Francisco Bay Area in California.
The suspect was taken into custody without incident, and the motive was not immediately known, said California Highway Patrol Sgt. Brian Pennings.
Passenger Mark Grabban, 29, said the gunman was talking "incoherently" when he boarded the bus and had argued with someone who had asked him to be quiet.
