Don Bosco Catholic Secondary School student Zaid Youssef, 17, and James Cardinal McGuigan Catholic High School student Michael Menjivar, 15, were killed in the early afternoon on Oct. 6.
The shots that killed them rang out in a field near Don Boscso where a large group of teens from both schools had allegedly gathered to watch a fight.
Funerals for the teens were held over the weekend in the north end of Toronto.
