Elizabeth Tracy Mae Wettlaufer is a Canadian former registered nurse who confessed to murdering eight elderly patients and attempting to kill six others between 2007 and 2016, using insulin injections at several long-term care facilities in southwestern Ontario. Her crimes came to light only after she voluntarily admitted them while in psychiatric care at the Centre for Addiction and Mental Health in Toronto in September 2016. Wettlaufer pled guilty in 2017 to eight counts of first-degree murder, plus multiple counts of attempted murder and aggravated assault, and is serving life sentences with no chance of parole for 25 years. A 2019 public inquiry found her actions were enabled by systemic deficiencies in Ontario’s long-term care system, concluding she would never have been caught without her confession
