(CNN) - Two Broward County Sheriff deputies who responded to the mass shooting at Marjory Stoneman Douglas High School were terminated for neglect of duty, Sheriff Gregory Tony said on Wednesday. The terminations of deputies Edward Eason and Joshua Stambaugh came as a result of an internal affairs investigation into the police response to the February 2018 shooting in Parkland, Florida. Of those seven, four have been terminated, including school resource officer Scot Peterson, who is facing criminal charges. He was accused of neglect of duty and failure to meet Sheriff's Office standards, the report says, and was terminated after the committee found him culpable. Peterson has faced sharp criticism for not going into the school building to confront the shooter when he heard gunshots.

MIAMI - Two additional deputies have been fired as a result of an internal affairs investigation into the agency's response to the shooting at Marjory Stoneman Douglas High School in Parkland that killed 17 people, the Broward County sheriff said Wednesday. At a brief news conference, Sheriff Gregory Tony said deputies Edward Eason and Josh Stambaugh were fired Tuesday for their inaction following the Feb. 14, 2018, shooting. A state investigative commission found that Stambaugh was working an off-duty shift at a nearby school when he responded to reports of shots fired at the school. Two other deputies were fired earlier this month for neglect of duty. The sheriff said no action was taken on three other deputies who were involved in the investigation.
