So now they start communicating after 4 are injured and the shooter is dead. They didn’t include the incident Friday that happened outside Max Hayes High School after school let out. I guess because “it wasn’t on school grounds”…it happened behind a vacant gas station adjacent to school grounds.

Wednesday’s shooting spree at SuccessTech Academy was the bloody climax to a week’s worth of gun-toting incidents across the Cleveland school district.

Oct. 3: A Margaret Ireland School student was arrested after school security officers found a loaded .25-caliber handgun with a six-shell clip in his book bag. The boy told officers he paid $25 for the weapon and carries it for protection. He was arrested after a gang fight involving nearly three dozen students, according to school security reports.

Cleveland police arrested the mother of a 15-year-old Genesis High School student who came to the school with a loaded .22-caliber gun, according to police reports. The woman told police her son had been jumped by students at school and called his mother on his cell phone. She brought the gun and confronted the attackers outside, who then scattered.

Monday: Security officers found a semiautomatic rifle, a scope and 43 rounds of ammunition in a duffel bag belonging to a 17-year-old special education student at Max S. Hayes Vocational School. The boy said he didn’t know how the gun got there.

Tuesday: A student brought a high-caliber, semiautomatic handgun to Michael R. White K-8 School.

Wednesday: The same day as the SuccessTech shooting, security officers confiscated a .38-caliber handgun from an East Technical High School student.

Last school year: Districtwide, there were 304 incidents involving possession of dangerous weapons such as guns and knives. Assaults on security guards nearly doubled from the previous year. At SuccessTech, there were just nine incidents.
