LONG BEACH, Calif. — A 16-year-old girl died and two men were wounded after being shot following a football game at a Southern California high school.

Long Beach police Sgt. Dina Zapalski says it's unclear what led to Friday night's shooting at Wilson High School. Police are searching for a suspect.

The girl died at a hospital. Her name has not been released.

An 18-year-old man and a 20-year-old man sustained non-life-threatening injuries.

City Councilman Gary DeLong described the girl as "an innocent bystander who was not involved" in the altercation.

It's unclear if any of the victims were students at the school.
