This is an accusation, not a finding. Sabrina Kauldhar has been charged with three murders and has not been tried for any of them. Everything below is what police and the courts have stated publicly.
On October 1, 2024, just after two in the afternoon, Toronto police answered a call at a house near Keele and Dundas Streets in the west end and found a woman dead with visible signs of trauma. She was Trinh Thi Vu, sixty-six. Police said she and Kauldhar knew each other, and did not say how.
The next afternoon, October 2, Niagara Regional Police were called to a reported disturbance at John Allan Park in Niagara Falls. They found a man critically injured. Lance Cunningham, forty-seven, was pronounced dead at the scene. His wife told the CBC that they had a thirteen-year-old daughter, that he had not deserved this, and that she wanted her husband back.
On October 3 a man was found stabbed in a parking lot in Hamilton. Mario Bilich, seventy-seven, a retired schoolteacher, died in hospital. Police said he had been followed.
The three deaths were reported in three cities by three different police services and looked unrelated. Hamilton investigators linked their case to the Niagara Falls killing because the description of the suspect matched, and the two of them were then linked to the active Toronto investigation. Kauldhar was arrested on October 4 at a hotel in Burlington. Police were still asking the public for help understanding what had happened over those three days, and were trying to identify a woman filmed at a shop in Burlington on October 1 buying the clothing Kauldhar had with her when she was taken.
Two of the three were strangers to her. Chief Bill Fordy of the Niagara Regional Police said that Cunningham and Bilich were both going about their business and that these were believed to be random attacks. Only the Toronto victim was known to her.
Asked whether the term applied, Fordy told reporters that by definition she was a serial killer: two or more offences, so he thought it a fair comment. That is a police characterisation of a charged case, made three days after the last death, and it is the reason this case is in the archive at all.
The proceedings then turned on her mental state, and the sequence is unusual enough to set out plainly. Her own lawyers first applied for a fitness assessment and then withdrew the application, saying she had instructed them to oppose it. The prosecution applied instead, and a judge granted it on the ground that there were reasonable grounds to doubt her fitness. In March 2025 she was found unfit to stand trial and ordered into sixty days of psychiatric treatment. Her lawyers argued after the reassessment that the Crown had not discharged its burden. On June 11, 2025 Justice Russell Silverstein ruled her fit, saying that if most of the symptoms of her illness had resolved through treatment it stood to reason that her unfitness, itself an earlier symptom, had resolved as well. He relied on the opinions of experts at the Centre for Addiction and Mental Health who had observed her.
She faces one count of first-degree murder and two counts of second-degree. Early reports gave the split differently, as second-degree in Toronto with first-degree from both Niagara and Hamilton; the later and more consistent reporting is one first-degree and two second-degree.
Police have not disclosed how the victims were killed, beyond the stabbing in Hamilton.
The count here is three charges and no conviction. Nothing in this case has been proved.
