Police responded to Woburn Collegiate Institute on Ellesmere Road, just east of Markham Road, around 3:20 p.m. on Monday.
The victim, later identified as 18-year-old Jefferson Peter Sardelli Guerrier, was shot in front of the school, police said. He was rushed to the hospital where he was later pronounced dead.
After the shooting, a 15-year-old boy went to a nearby hospital with gunshot wounds. He is now in stable condition.
In a letter sent to students and their families Tuesday, the principal of Lester B. Pearson Collegiate Institute identified Guerrier as a former student at that school.
“We know you will join us in expressing our deepest condolences to Jefferson’s grieving family, friends, and former teachers and classmates,” Principal Anthony Hack wrote in the letter.
“Jefferson attended Lester B. Pearson CI from 2017 to 2022 and will be greatly missed by our school community. As a student he participated in the Pearson Band and the Skateboarding Club. His playful and cheerful nature endeared him to staff and students alike.”
On Wednesday, investigators identified a suspect in the incident as 17-year-old Mustafa Kadhem of Toronto.
He is wanted for second-degree murder and should be considered armed and dangerous, police say.
Because of Kadhem’s age and his protection under the Youth Criminal Justice Act, TPS had to seek judicial authority to identify the juvenile. The authorization expires on November 7 at noon or upon his arrest, whichever comes first.
After termination, the photograph and name of the suspect can no longer be released under the provisions of the Youth Criminal Justice Act.
