Woman, 26, dies in hospital after double stabbing in Oshawa

A woman is dead and a second woman is injured after a stabbing in Oshawa over the weekend, police say.

Durham Regional Police said officers responded to an address on Simcoe Street at around 4 a.m. Sunday for reports of an armed person.

Officers located two women suffering from stab wounds, both of whom were taken to Toronto-area trauma centres.

One of the women, identified as 26-year-old Katie Kainz, has since died, police said. She is Durham Region’s sixth homicide victim of 2023.

The other woman suffered critical injuries and is reported to be in stable condition.

Police said suspect information is currently not available but added that the stabbing appears to have been an “isolated incident.”

Investigators are looking to speak with anyone who has new information or video footage from the area.

Durham police first tweeted just before 5:30 a.m. on Sunday that Simcoe Street North was closed between Brock Street East and Adelaide Avenue East for an investigation.

It wasn’t until hours later that police tweeted that they were there for a stabbing, with officers later adding that no suspect information was available and that it was believed to be an “isolated” incident.

Further details about the stabbing, including information on the victims, wasn’t provided until Tuesday.
