“Of all the schools in America, you would think this would be the safest one right now. This is so outrageous it’s almost impossible to believe,” Rubio said in a statement Tuesday.
The Broward Sheriff's Office confirmed to ABC News that Carotti was first found by a student, who then notified a BSO sergeant patrolling the interior of the school.
Just thirty minutes before, shooter Nikolas Cruz's brother Zachary was arrested by Broward deputies for trespassing on school property. Three other students were also arrested in separate, unrelated incidents; two for carrying knives on school property, and one for posting threats to social media, according to the sheriff's office.
Carotti will be suspended without pay pending the outcome of an internal affairs investigation, the sheriff's office said.
