Officers responded to reports of multiple gunshots fired on the corner of Leibrandt Avenue and Raymond Street about 9:15 p.m. Saturday.
A witness claimed to have heard gunshots and saw three males running away. Officers found eight shell casings from what initially looks to be a .380 caliber gun. No victims were found, but two unoccupied cars were hit.
Officers are looking for additional witnesses, and said it is unclear if someone was targeted by the attack.
Anyone with information should call Santa Cruz Police at 420-5820.
