BAKERSFIELD, Calif. (AP) – A man accused of opening fire aboard a Greyhound bus in California has pleaded not guilty to one count of first-degree murder and five counts of attempted murder. 33-year-old Anthony Devonte Williams of Capital Heights, Maryland, entered his pleas Thursday in Kern County Superior Court. The shooting occurred Feb. 3 as the bus was on Interstate 5 between Los Angeles and Bakersfield. Authorities and a witness say a passenger was cursing and muttering incoherently before he opened fire. Other passengers disarmed the man and forced him off the bus. A woman was killed and five other people were wounded.
