Authorities have released surveillance and body camera footage of a man who shot at two people, one fatally, in a Long Beach, CA, sports bar in October before police arrived and shot him dead.

In a community briefing video released Friday, the department detailed the Oct. 23 shooting. It remains unclear why the man began shooting inside the establishment, the Los Angeles Times reports.

About 12:20 a.m., several patrons outside the Bottoms Up sports bar flagged down a Long Beach police officer to report a man wearing a Lakers jersey inside who was shooting at people.

While the patrons were talking to the officer, more shots were fired. The officer then walked up to the bar’s entrance and positioned himself so he could see inside the bar.

According to the eight-minute video, he saw a man pointing a gun at people inside the bar and fired two shots inside, striking the man, later identified as Delfon Kinney, 48.
