Six people were killed in a shooting rampage at a college in the US state of California Friday, CNN reported.
The incident occurred in Santa Monica College, California, that ended Friday with the gunman clad in tactical gear dead in a college library and a "person of interest" in custody, authorities said.
"We are not convinced 100 per cent that the suspect who was killed operated in a solo or alone capacity," Santa Monica police chief Jacqueline Seabrooks told reporters.
The comments came as police and firefighters searched the sprawling campus of Santa Monica College for other possible victims or shooters. By early evening, authorities declared the campus clear.
The gunman has not been identified by authorities, Seabrooks said.
