In a tragic incident that shook the city of Mississauga on Thursday, a 19-year-old was fatally shot by the police. The teen was believed to have stabbed a family member prior to the fatal shooting. The 39-year-old stabbing victim managed to find refuge at a neighbour’s residence, where he sought help. The province’s police watchdog confirmed the details of the incident on Thursday night.

Details of the Incident

According to the Special Investigations Unit (SIU), an independent agency that investigates incidents involving police that have resulted in death, serious injury, or allegations of sexual assault, the police responded to a call regarding a domestic dispute around 10:30 p.m on Thursday.

The stabbing victim was found at a neighbour’s residence where he had sought help.

Negotiation and Fatal Shooting

The SIU reports that the officers “attempted to negotiate” with the 19-year-old man. However, the situation escalated and resulted in one of the officers discharging his firearm multiple times. The young man was struck and was pronounced dead at the scene. The exact circumstances surrounding the shooting are still under investigation and no further details have been released at this time.

The Aftermath

The 39-year-old stabbing victim was transported to a nearby hospital with serious injuries. His current condition is not known.
