A 30-year-old woman, Sabrina Kauldhar, was arrested and charged with three murders over three days in Canada, earning her the label of a serial killer from police.

The attacks occurred in Toronto, Niagara Falls, and Hamilton between Tuesday and Thursday. Kauldhar was arrested in a Toronto hotel after police linked her to the killings.

Her victims included a 60-year-old woman in Toronto, a 47-year-old man in Niagara Falls, and a 77-year-old man in Hamilton, as reported by CBS News.

While the Toronto victim knew Kauldhar, the other two were believed to be random attacks.
