After the blaze was extinguished, firefighters told police they had found a suspicion device on the roof of the market while trying to determine the cause. The item turned out to be a vintage military rocket, Wisehart said. Police responded along with members of the Riverside County Sheriff's Department Hazardous Device Team, who rendered the rocket safe.
The rocket was determined to be a M29A2 inert training round, Wisehart said, and the device's motor was ignited by unknown means. It appears that the general direction the rocket was pointed was towards a police facility, Wisehart said.
