Police ID 2 more persons of interest in Etobicoke double shooting

Toronto police have released security camera images of two more "persons of interest" in the shooting deaths of two teenagers in Etobicoke last week.

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. 

On Wednesday last week, police released five photographs of "persons of interest" and appealed to the public for help identifying them, and on Sunday distributed two more images. Police earlier said that they believe up to 40 people may have witnessed the shootings.
