Broward Sheriff Scott Israel said Thursday the school resource officer stationed at Marjory Stoneman Douglas was suspended without pay after he learned the deputy never went into the building when the shooting began.

Scott Peterson chose to resign and retire Thursday morning Israel said.

A review of surveillance video showed that the deputy was in postion and armed but never entered the building. He remained stationed outside the building for “minutes” while the shooting went on.

He said the video was part of the investigation and Israel said it may never be released.

On Feb. 14, deputies say Nikolas Cruz, 19 walked into his former school and opened fore with an AR-15 killing 14 students and three teachers.
