Edmonton police discovered a human head in a garbage bag in a back alley in a northeast neighbourhood this morning.

The alley is in the Balwin community near 132nd Avenue and 72nd Street.

Roseanne Rochette, who lives nearby, said she was returning home around 11:30 p.m. Tuesday when she spotted a black garbage bag sitting in the alley.

"It wasn’t much. I mean, it was garbage in a back alley, what I seen, and I thought nothing of it," Rochette said.

The next morning, police knocked on her door and told her a head had been found in the bag.

Rochette said she's disturbed that it was found so close to her home.

"It’s eerie. Terrifying. … Way too close for comfort."

Jesse Whitnack, whose apartment balcony overlooks the alley, said at least 15 EPS officers were combing through the alley by 7:30 a.m.

"All I know is I woke up and there were cops everywhere," he said.

Sources tell CBC News the head belongs to a man and the case is directly related to a body that was found last weekend east of Edmonton, near Ranfurly, Alta.

RCMP are investigating that case.
