She's also charged with murders in Hamilton and Toronto
A major breakthrough by police in connection with the murder of Lance Cunningham, who was found in John Allan Park on Wednesday in Niagara Falls.
He was found with critical injuries, and died at the scene.
They've arrested 30-year old Sabrina Kauldhar, of Toronto, charging her with 2nd degree murder.
In fact, police have also charged her with 2nd degree murder in the death of a 60-year old woman in Toronto, whose body was found with trauma on Tuesday.
Then, police say 77-year old Mario Bilich was found yesterday in a MacNab Street North parking lot in Hamilton, with stab wounds. He later died in hospital.
Police linked the three murders together after matching descriptions of the suspect, and arrested the accused in Burlington yesterday at 5:45pm.
She is charged with 1st degree murder in the Hamilton case.
Investigators believe Mario Bilich and Lance Cunningham were randomly targeted, while Kauldhar was known to the Toronto victim.
They're asking anyone with information on these crimes, or if you saw Kauldhar between Tuesday and her arrest, to call them.
