Newmarket Crime: Self-Defence Claim Leads to Murder Conviction
Expert Insight
This case highlights the critical need for understanding the legal boundaries of self-defence.
September 1, 2026 · Legal Brief

In a dramatic courtroom decision, McKenzie Gill was found guilty of second-degree murder in the fatal stabbing of her ex-boyfriend, Blake Bibby, at his Millard Avenue apartment in Newmarket. This verdict came after a nine-day trial where Gill claimed she acted in self-defence during a heated altercation on July 14, 2024. Justice Vanessa Christie, however, concluded that Gill's actions were deliberate and not driven by fear of imminent harm.

The court had previously heard about the tumultuous and violent history between Gill and Bibby, with past instances of Bibby assaulting Gill. Despite these claims, Justice Christie emphasized that on the night of the incident, Gill's actions were retaliatory rather than defensive. Her conviction has left both families grappling with the outcome, as Gill was taken into custody immediately following the decision. UL Lawyers Legal Team
