Toronto police have identified a teen who was gunned down in the city’s north end.

Police say William (Billy) Nathanson, 19, died in hospital after being shot behind a townhouse complex on Sheppard Avenue West near Jane Street Monday night.

Det.-Sgt. Pauline Gray told a news conference that Nathanson was ambushed by two people as he returned home from work. Gray added that that suggests the assailants knew his schedule.

Police want to hear from anyone with information about the case.
