Though the shooting wasn't captured on video, a neighbor's security camera recording confirmed that Cromwell had told Chen to stop and put the car in park before he began shooting. But prosecutors pointed to some inconsistencies in his account: He had told a detective that he yelled at least 10 to 15 times for Chen to stop, but the recording only showed him doing so three times before he started firing. In addition, Chen had his foot on the brake when authorities arrived and found him dead inside the minivan, leading prosecutors to cast doubt on the security guard's claim that he was at risk of being run over. Additional testimony revealed that Cromwell was supposed to call police when a situation seemed like it might escalate, rather than use deadly force.
