A man who was critically injured after he was found shot and stabbed at a property in southwest Edmonton Tuesday has died.

The man, 21, died in hospital. Police are calling his death suspicious.

Insp. Brian Nowlan listens to a reporter's question near where a man was shot and stabbed early Tuesday afternoon. CBC

Officers responded to an abandoned farm at 170th Street south of Ellersie Road after getting a call around noon from someone who said he was stabbed.

The man didn't know his exact location so it took police a half hour to locate him using signals from cell phone towers.

Insp. Brian Nowlan says the man was stabbed and shot, which resulted in multiple injuries.

Nowlan says it isn't clear whether the man sustained the injuries at the site, which is an abandoned farm with a number of buildings.

"There's some evidence to show he may have driven there in distress," Nowlan said. "There are some tracks going through a field that are actually leaving the street, but whether those are actually his or not, we're yet to determine."

The man was taken to hospital by STARS air ambulance.

Nowlan says it took police an hour and a half to go through each building on the site to make sure no one else was there.
