Hamid Aminzada, a recent immigrant to Canada from Afghanistan, died in hospital after the stabbing at North Albion Collegiate Institute, a high school with about 1,000 students that's in the northwest Toronto suburb of Etobicoke. Police say Aminzada had intervened in an ongoing argument between two other students.
A 17-year-old boy turned himself in to police on Tuesday evening accompanied by his lawyer and has been charged with second-degree murder.
The stabbing happened just after noon Tuesday in the hallway of the school at 2580 Kipling Ave., just north of Finch Avenue West.
Aminzada died as police were searching the school for his attacker.
The incident marked the first time a student has been killed inside a Toronto high school since 2007, when 15-year-old Jordan Manners was shot to death inside C.W. Jefferys Collegiate Institute.
Student came from Afghanistan
At a press conference outside the school Tuesday afternoon, principal Naeem Siddiq described Aminzada as "quite focused on his family and his future" and that he was "very involved, very kind and well-known to teachers and students."
Aminzada hails from a large family and came to Canada a little more than two years ago from Afghanistan. He was in his second year at the school.
Siddiq added that there was no indication that Aminzada had troubles with any other students.
"This is a sombre day for the entire TDSB community, especially the students and staff at North Albion, as we mourn the tragic loss of this young life," said Donna Quan, director of education for the Toronto District School Board.
Quan spent the day at the school Monday, and told CBC Radio's Metro Morning show Wednesday she learned that Aminzada was "a very caring young man who contributed to the life of his school."
Quan said classeswill resume Wednesday, and said that grief counsellors will be there to help students dealing with Aminzada's death.
