California shooting: 4 killed, 4 injured at Halloween house party

Four people were killed and several others wounded in a shooting in northern California on Halloween night. Posts on social media suggest it took place at an AirBnB ‘mansion party’ that saw over 100 people attending.

The Contra Costa County Sheriff's Office announced the casualties in a tweet Friday. It said it is working with the police department in the city of Orinda, where the shooting took place. Neither department has released further details.

According to ABC7 News, the call alerting police of the shooting took palce at 10.45pm on Thursday night. Video from the scene posted by KGO-TV showed multiple patients being loaded into ambulances as others limped away from the scene. Video also showed police talking to people who appeared injured.

According to the East Bay Times, AirBnB is investigating the incident. 

A dispatcher at the sheriff's office said the public information officer would release more information later this morning, but he did not provide a time.

The shooting comes days after another shooting in Long Beach, California, where a gunman killed three and wounded nine. That shooter is still at large, with police having issued an advisory to look out for him.
