Six people are dead, and 12 are injured after a shooting in Sacramento, California, overnight, cops said.

Witnesses said there was a fight, then shots fired from a moving vehicle, according to KABC.

Police did not identify or describe any suspect. The investigation is ongoing.

As part of the investigation, officers closed 9th Street to 13th Street between L Street and J Street.

Community activist Berry Accius said he arrived at the scene shortly after the shooting.

“The first thing I saw was like victims,” he told The Associated Press. “I saw a young girl with a whole bunch of blood in her body, a girl taking off glass from her, a young girl screaming saying, ‘They killed my sister.’ A mother running up, ‘Where’s my son, has my son been shot?’ You know, commotion, trauma. It’s just a lot of things that, you know, you don’t want to see.”

Update – 4:06 PM: Officers now say 12 people were injured. From cops:
