Police don't have any suspect decriptions after a teen was reportedly shot in the parking lot of the Pierre Berton Resource Library on Rutherford Road in Vaughan.
Officers were originally called around 1:45 to reports of a shooting, but when they first arrived, they found no evidence of a crime.
It wasn't until later, when a teen showed up with his parent in hospital, did police return to the parking lot to search for evidence.
But they are asking for the public to come forward with information, since they don't have much to go on.
So far, no arrests have been made.
