Peterson, 54, came under scrutiny after 19-year-old Cruz entered a school building with an AR-15 rifle and killed 14 students and three educators on Valentine’s Day. Cruz later confessed, police said.
The sheriff said video shows Peterson was outside the building for “upwards of four minutes” while students were gunned down inside.
“What I saw was a deputy arrive … take up a position and he never went in,” the sheriff said at a news conference. “There are no words. I mean these families lost their children. We lost coaches,” Israel said. P
eterson resigned, and subsequently retired, at 12:37 p.m. Thursday after he was suspended without pay earlier in the day, Israel said. An investigation into what happened will continue.
Peterson’s resignation ends a more than three-decade career with the agency, where he was often regarded by peers as a dependable employee who could communicate well with both staff and students.
