Two officers were shot dead inside a home in Innisfil, Ontario on Tuesday evening, before they drew their firearms, the Special Investigations Unit said today. South Simcoe Service police officers were dispatched to a home near 25th Side Road and 9 Line just before 8 p.m. on October 11, following a call about a disturbance coming from a neighbor's house. Initial reports from the Special Investigations Unit stated that Morgan Russell, 54, arrived at the home and later engaged in a shootout with a 23-year-old man armed with a semi-automatic rifle. However, SIU spokesperson Christie Dennett told CTV News Toronto that a third officer was in the house and was the person who exchanged fire with the 23-year-old man. It is still unclear how the shooter died. The Special Investigations Unit added that investigators will learn more after the autopsy scheduled for Friday. Also, Northrop and Russell were seriously injured in the shooting and were taken to the hospital, but later died from their wounds. Although the SIU has not confirmed the identity of the 23-year-old man, CTV News Toronto identified him as Chris Doncaster through family friends and his former girlfriend, with neighbors also telling CTV News Toronto that Doncaster was the grandson of an elderly couple living in the house. Little else is known about him, although it appears he briefly served in the Canadian Armed Forces. In this regard, CTV News Toronto learned that Doncaster was the suspect in the fatal Innisfil incident, where the Department of National Defence confirmed that a man named Christopher Joseph Doncaster was a member of the Canadian Armed Forces from May to December 2020. The department said Doncaster was a soldier but did not complete basic training. The new details about the shooting come after a candlelight vigil for the fallen officers was held on Wednesday evening, attended by hundreds from the community, including Innisfil Mayor Lynn Dollin, but the families of the slain officers did not participate. Dollin said it will be a "long process" to heal in the town, which is about 70 kilometers north of Toronto, adding, "I think our community is still in shock and last night helped us as we can come together and support each other. But it will be a long process for us."
