Freeway shootings across Southern California prompt CHP investigation Published article RIVERSIDE, Calif. - "What we're asking from the public is victims of this immediately call 911 and give us their exact location and time and description -- even if it's just a description of the vehicles around them," CHP Officer Florentin Olivera said. CHP investigating wave of freeway shootings in SoCal "We are looking at the traffic cameras for leads, but need people to help us" he adds. Some drivers actually report being hit after they get off the freeway, so investigators are not sure if those are related to the on-freeway series, which extends mostly along the 91 freeway.
