SACRAMENTO, Calif. — Law officers searched for a gunman after one man was shot to death and two others wounded in a parking lot at the edge of a Sacramento community college campus, officials said.

The suspect ran from the scene after the shooting near a campus baseball field on Thursday afternoon, and was not found in a sweep of the campus and surrounding neighborhood, Sacramento police Sgt. Doug Morse said.

One victim was declared dead at the scene, another was hospitalized and expected to survive, and the third was grazed by a bullet and was being questioned by investigators, authorities said.

The shooting began as an argument between two groups of men, said Dustin Poore of Los Rios police, who patrols Sacramento City College.

A physical fight escalated when a knife and gun were pulled out, said police in a news release late Thursday. Police said the shooting victim was believed to be involved in the fight.

The release added that gang involvement wasn’t being ruled out.
