The Ontario province’s police oversight agency has determined that an officer acted within the bounds of the law when he fatally shot a landlord who had killed two tenants during a dispute at a residence in east Hamilton, Ontario. Director Joseph Martino of the Special Investigations Unit (SIU) cited section 34 of the criminal code as the basis for his decision, stating that there were “reasonable grounds” for the officer to fire his weapon through the front door of the Stoney Creek home during a stand-off. The incident occurred on May 27th of last year on Jones Road, just north of Barton Street East.

According to the police, three people died during the incident. The victims, Aaron Stone, 28, from Hamilton, and Carissa MacDonald, 27, of Stoney Creek, were found dead by police when they arrived at the scene in response to a report of shots fired. Homicide detectives say that Stone and MacDonald, who were both residents of the address, were attempting to flee when they were shot and killed by the 57-year-old landlord. The landlord then barricaded himself inside the home with several firearms.

The stand-off with the police lasted nearly four hours and came to an end when the shooter fired shots at an armored police vehicle parked in his driveway and was subsequently struck by return fire. Director Martino explained that “In the circumstances, the officer had every reason to believe that his life, and the life of third parties, was in imminent peril and that responsive force was required to defend against loss of life or grievous bodily harm.”

After the stand-off ended, the SIU revealed that the police used the armored vehicle to breach the front door and deployed a robot to search for the suspect. The robot discovered two firearms, which were returned to the officers, and then reentered the home to locate “an unresponsive complainant in the garage.” A total of three firearms, along with magazines and ammunition, were seized.

Aaron Stone, 28, was a member of the International Brotherhood of Electrical Workers (IBEW), while Carissa MacDonald worked as an educational assistant for the Brant Haldimand Norfolk Catholic District School Board (BHNCDSB). Police informed Global News that the families of the victims were “devastated and stunned” by the incident. According to detectives, MacDonald and Stone were engaged to be married.

Property records obtained by Global News indicate that the shooter purchased the Jones Road home in 2003 for $115,000 from a woman who was reportedly his mother. The SIU has now concluded its investigation into the incident.
