CNN) Former Broward County Sheriff's Deputy Scot Peterson -- who was criticized for how he responded when a gunman opened fire at Marjory Stoneman Douglas High School -- has been charged with 11 counts, including felony child neglect charges, authorities said.
Peterson retired after the February 2018 massacre at the Parkland, Florida, high school that left 17 people dead, and is collecting a pension .
He was fired Tuesday at a disciplinary hearing by new Sheriff Gregory Tony. The firing could affect Peterson's retirement pay, Tony said.
Peterson, who was a school resource officer, is facing charges of child neglect, culpable negligence and perjury in connection with the deadly shooting, according to a release from the State Attorney's Office.
