Three people were killed and four injured in a shooting at a bowling alley in Torrance, Calif., on Friday, Jan. 4, 2019.

In addition to the three dead at the scene, four others were treated for injuries. Two men were transported to the hospital by ambulance, while two others “opted to seek their own medical attention.”

“There was a big group of people, seemed like they were having fun earlier,” eyewitness Dana Scott said. “People were laughing, having a good time, next thing we know there was a fight and it was the girls. … So they were yelling and cussing and fighting and people were on the floor and then some young men got into the fight. … Probably not even a good minute later, we heard gunshots.

“People started running to the back of the bowling alley and on the floor and between the lanes and between the cushions and the benches. … It was nothing good to see.”

Torrance Police Department said it responded to the scene at 11:54 p.m. They had tweeted just after midnight, “Reports of shots fired with multiple victims down.”
