The victim was hit by one or more firearm projectiles around 9:10 p.m. while she was in Langelier Park, in the heart of a residential area.

“We stayed calm and we spoke to him,” said Stéphane Signori-Drouin, a neighbor who has paramedic training and who rescued the victim. “I got my first aid kit which I drag in my car, we took care of controlling the bleeding.”

Several neighbors in the area witnessed the event.

“We heard big shots,” said one of the residents of the area. "I thought it was fireworks."

The teenager suffered serious injuries that required his transfer to a Montreal trauma center for surgery, but he is now out of danger.

The police were quickly able to spot a suspect, an elderly man in his twenties who was to be met by investigators.

“We are in the process of sorting out a bit what happened, the involvement of everyone in this story,” said Bruno Marier of the Repentigny Police Department.

Two other individuals were also wanted in the moments following the shooting, without the police being able to arrest them during the evening.

"We saw people running around, then a person running on the opposite side, the person crossed the street and was running with something in their hands," says a neighbor in the area.

Several complaints have been filed with the City of Repentigny regarding loitering in Langelier Park. Citizens say that the police are often called to intervene late at night.

“I clearly heard a fight late at night, it was screaming, and it was coming violent from what I heard. So I called the police,” said a neighbor. "It's starting to worry me."
