MIAMI • The former Florida deputy who stood outside instead of confronting the gunman during last year’s Parkland school massacre was arrested Tuesday on 11 criminal charges related to his inaction.

Broward State Attorney Mike Satz said in a statement that 56-year-old Scot Peterson faces child neglect, culpable negligence and perjury charges that carry a combined potential maximum prison sentence of nearly 100 years.

Peterson, then a Broward County deputy, was on duty as the school resource officer during the February 2018 shooting at Marjory Stoneman Douglas High School but never went inside while bullets were flying. Seventeen people died and 17 were wounded in the attack, many on the building’s third floor after Peterson arrived, investigators said.

One of the victims was 14-year-old Gina Montalto, whose father Tony Montalto said families wanted justice to be done.

“We are happy to see some accountability for this tragedy,” said Montalto.
