The Thunder Bay Police Service arrested 45-year-old Christopher William Gregorchuk this week in Thunder Bay, Ontario. He is accused of attacking a woman with a hammer on January 31, 2026, while he was allegedly breaching bail conditions from a previous matter.
Gregorchuk now faces several charges, including assault with a weapon and possession of a weapon for a dangerous purpose. Police took the suspect into custody in early March 2026, following an investigation into the winter attack.
The suspect has a history of violence in the city, including a 2011 conviction for his role in a 2009 homicide. In that case, 36-year-old Richard Ouimet was beaten to death before his body was moved to a remote area and burned.
For the 2009 crime, Gregorchuk pleaded guilty to manslaughter and indignity to human remains, receiving a 10-year prison sentence in 2011. This latest arrest has caused concern in the community regarding public safety and the rules for releasing people with a history of violence back into the neighbourhood.
