According to District Attorney Kim Ogg, all evidence was presented to a jury who handed down a no-bill, declining to charge anyone with a crime. “As with all officer-involved shootings, we presented all of the evidence to a grand jury and gave parties the opportunity to come forward to testify,” Ogg said.
