Long Beach police are investigating two separate shootings on Thursday evening and early Friday morning that left no victims and few witnesses, authorities said.

In the first incident, officers heard gunshots around 6:45 p.m. near Lewis Avenue and 20th Street in the Poly High School neighborhood.

“Officers canvased the area and located bullet casings,” officer Ben Hearst said.

They found several witnesses, but no victims. The investigation is ongoing, but LBPD does not have a suspect description available yet, Hearst said.

Later that night around 1:15 a.m., officers were sent to Linden Avenue and 56th Street in North Long Beach on a call about shots fired.

“Officers arrived and found evidence a shooting occurred,” Hearst said. “Officers located several witnesses, but did not locate any victims or suspects.”

The evidence found was at least one bullet casing, he said.

Anyone who may have information regarding the incident should contact the Gang Enforcement Section at 562-570-7370.
