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.
With Monday's appeal, homicide investigators have now released a total of eight images of men they are trying to identify. Police earlier said that they believe up to 40 people may have witnessed the shootings.
Police are asking anyone who may have witnessed the incident or the persons of interest themselves to contact Det.-Sgt. Peter Trimble at 416-808-7400 extension 77394.
