A man whose severed head was found in a bag in a northeast Edmonton alley earlier this week is the victim of a homicide that wasn't a random act of violence, police said today.

RCMP Insp. Gerry Scott gave more details of the killing while speaking to reporters at a news conference Friday morning. 

The body was discovered in a ditch near Ranfurly, Alta., last Saturday.
