Toronto police have released images of a woman they believe may be aiding a man suspected of fatally stabbing a man last week in the city's west end.

David Blacquiere, 54, of Angus, Ont., was stabbed in the chest several times near Weston Road and King Street, north of Lawrence Avenue West on Tuesday Nov. 14.

He was later pronounced dead in hospital.

The 18-year-old man of no fixed address is wanted for second degree murder.
