Authorities say three people were fatally shot and nine others injured at a home in Long Beach, California.

The Los Angeles Times reports that Long Beach fire spokesman Jake Heflin says firefighters arrived at the home around 10:44 p.m. on Tuesday to a scene “filled with chaos.”

First responders were seen outside the home treating seven victims in a nearby yard, ABC 7 reported. Reports indicated that there may have been a Halloween party at the house at the time of the shooting.

The department says three men were dead and the nine others were injured. Their conditions weren’t immediately available.
