A former investigator's lawsuit against San Francisco District Attorney Brooke Jenkins still survives after several years of proceedings. OAKLAND, Calif. (CN) — A federal judge denied San Francisco District Attorney Brooke Jenkins’ push to toss a retaliation claim against an investigator over his termination related to a 2017 officer-involved shooting investigation. In a mixed-bag ruling on summary judgment, Senior U.S. District Judge Jeffrey White denied the district attorney’s motion for judgment on former district attorney investigator Jack Arne Friedman’s retaliation claim. Samayoa is the first San Francisco officer to ever be charged with criminal homicide for a killing in the line of duty. Under former San Francisco District Attorney Chesa Boudin, Friedman was the investigator who signed the arrest warrant.
