Police in Montreal said last month that the shooting outside a hospital in the area, originally thought to have targeted officers, was actually a bullet.
The shooting took place around 1:30 am on August 24 at the parking lot of McGill University Health Center at the western end of the city, where two bullet holes and projectiles were found.
Two police officers hid behind the vehicle and one was slightly injured.
Police in Montreal say the detective analyzed the area and examined the images, and they now believe the shot was fired from a green space just south of the hospital.
However, police have determined that due to the terrain, it is unlikely that the shooter intentionally fired at the police officer.
Police said the most plausible scenario in the statement was that ammunition could have been fired, a drifting projectile colliding with the side of a building near police officers, and the ricochet could have caused injuries.
