The death of a Toronto woman found in a Newmarket home last Friday is being investigated as a homicide, York Regional Police say.
In a news release Tuesday, police say officers were called to a home in the area of Prospect Street and Gorham Street for reports of an injured person.
They arrived to find 22-year-old Nicole Mercer. She was taken to hospital, where she was pronounced dead.
A post-mortem investigation found Mercer died of a gunshot wound, police say.
Investigators are asking any witnesses who have not yet spoken with them to contact police.
