A 21-year-old Toronto man is wanted on a Canada-wide warrant in connection with a double stabbing Friday night.

Det. Sgt. Graham Gibson said the suspect went to a home on College Street near Dufferin around 8 p.m. Friday night to visit with a family member. An argument ensued and the victim suffered serious stab wounds. Sarah Vermelhudo, 38, ultimately succumbed to those injuries in hospital.

A 59-year-old woman was also injured while trying to intervene. She suffered minor injuries and was treated at hospital before being released.

The suspect then fled westbound on College and north up Dufferin.

Police say they have recovered a weapon believed to have been used in the attack but would not elaborate.

An arrest warrant has been issued for Shayne MacDonald, wanted for second-degree murder and attempted murder. He’s described as being five-foot-10, 160 pounds with light-brown hair.

MacDonald is considered violent, armed and dangerous.

Anyone with information is asked to contact police.
