(23.2.2018) Records show Peterson was familiar with Nikolas Cruz, the 19-year-old student who had been expelled from Stoneman Douglas for behavioral problems. As Cruz approached the building, a staffer spotted him and radioed that he was nearing the school. But Israel said video showed Peterson stood outside the building for “upwards of four minutes” while Cruz was shooting. “What I saw was a deputy arrive … take up a position and he never went in,” the sheriff said.
