A large outdoor block party in Toronto, Canada turned violent, as a shooting left two people dead and at least 19 others injured, including an infant.
According to Toronto Police Chief Bill Blair, two people were killed Monday in the gunfire, a teenage girl and a man in his twenties.
He did not provide the age of the child who was injured, but said the injuries are "not life-threatening and the child will be fine."
According to ABC News, it's unclear how many people actually fired shots, but there was more than one person responsible for the gunshots.
As Blair told reporters:
"It is the most serious crime of its kind that has ever taken place in the city of Toronto."
Police said they had one "person of interest" in custody and were looking for other suspects. Blair said "the person of interest" was also injured in the gunfire:
"The only information I have is that it was handguns involved in this. We don't have information at this point in time about the weapons that were used, although one weapon has been recovered at the scene."
This level of violence is something that has never been experienced by Toronto Police and Blair described the incident as "unprecedented" in Canada's history.
