Two more deputies were fired Wednesday after the Broward Sheriff’s officials completed an internal affairs investigation into the deadly mass shooting inside Marjory Stoneman Douglas High School – a shooting that has led to the department’s former boss being suspended and fighting to get his job back.

BSO Sheriff Gregory Tony addressed the report at a morning press conference, saying a total of seven deputies were investigated with three - Dep. Brian Goolsby, Dep. Michael Kratz and Dep. Arthur Perry - able to keep their jobs.

A total of four - including longtime school resource officer Scot Peterson along with deputies Brian Miller, Edward Eason and Joshua Stambaugh - lost their jobs as a result of what Tony called "neglect of duty."

The investigation’s conclusion comes just one week after the man Tony replaced, Scott Israel, testified in Tallahassee in an effort to get his job back. Israel was suspended earlier this year by Governor Ron DeSantis over his handling of the shooting and the events that led up to it.

Earlier this month, Peterson was charged in the incident that killed 17 people on February 14, 2018 at the Parkland school.

Peterson, who had served as a resource officer at the school for years and retired shortly after the shooting, had come under fire from the parents and families of victims after surveillance video showed him staying outside of a building while confessed shooter Nikolas Cruz was inside.
