William Nathanson, 19, was gunned down in Toronto on Nov. 22, 2010.
Toronto police have identified a teen who was gunned down in the city's north end.
Police say 19-year-old William (Billy) Nathanson died in hospital after being shot behind a townhouse complex on Sheppard Avenue West near Jane Street on Monday night.
The shooting followed a violent weekend which saw at least eight shootings, including another homicide.
