2 students bring knives to Stoneman Douglas,

Two students were arrested Tuesday, accused of bringing knives to the Parkland school where 17 people were killed by a gunman on Feb. 14. A third student is being mentally evaluated for making online threats.

Compounding the anxiety emanating from the campus, a Marjory Stoneman Douglas High School deputy was suspended for sleeping on the job after being caught by a student on Monday evening, according to the Broward Sheriff ’s Office.

The student notified a sergeant patrolling the school that Deputy Moises Carotti was asleep in his patrol car, said Veda Coleman-Wright, a spokeswoman for the Sheriff ’s Office.

The sergeant knocked on Carotti’s window to wake him up, she said. Carotti was suspended with pay while an internal affairs investigation is launched.

Tuesday’s school day began with the arrest of Jordan Salter, 18, after a conflict in the cafeteria. She poured cereal on another student’s head after he asked Salter’s friend a sexually offensive question. When the boy leaned in close to Salter’s face, she pulled a 2-inch black knife from her bra, opened it and displayed it, according to a report from the Sheriff’s Office.

The next arrest came in the afternoon, when school authorities learned that Gavin Stricker, 17, had brandished a knife on a bus Monday. He was called into the school’s office and a 9-inch knife was found in his backpack, according to a juvenile arrest report.

The third event developed after screenshots of a sophomore’s Snapchat account circulated around campus. It showed the boy posing with a gun in his waistband along with images of bullets.

The student, who was hospitalized for a mentalhealth evaluation, faces a misdemeanor charge for disrupting school with the social media threat.
