Broward County Sheriff Scott Israel says the armed school resource officer assigned to Marjory Stoneman Douglas High School on the day of the school shooting "never went in."
The deputy who was on duty at the high school where 17 people were massacred waited outside the building for about four minutes without ever going in.
Deputy Scott Peterson resigned after being suspended without pay by the sheriff's office.
Israel said he made the decision after reviewing video surveillance and interviewing witnesses, including the deputy himself. The sheriff says Peterson responded to the building where the shooting took place, took up a position outside a door and never went in.
When asked what Peterson should have done, Israel said the deputy should have "went in, addressed the killer, killed the killer."
After the shooting, the Broward Sheriff's Office said Cruz walked to a Walmart to buy a drink at Subway, then strolls to McDonald's and leaves. 80 minutes after the gunfire at the high school, a Coconut Creek Police officer arrested Cruz in Coral Springs. He's now being held on 17 counts of premeditated murder.
