Unidentified men may hold key to solving string of stabbings

Four months after a woman was killed and four others injured in a bewildering stabbing rampage, Calgary police released photos of three people who they say may have information about the incidents.

Investigators said Tuesday the images come from surveillance video from the Mac's Convenience Store on 12th Street and 17th Avenue Southwest, across the street from where Jacqueline Clara Crazybull, 44, was found stabbed to death in July.

At the time, Calgary police said theybelieved four others were stabbed by the same group of attackers over the course of one hour on the same early morning. Investigators said the victims appeared to be random and had no links to each other.

Witnesses gave police a description of three or four black men between 20 and 30 years old in a light-coloured, newer-model sedan.

Police said Tuesday they need to identify three men believed to have been in the area before the stabbings because they may have information that could help the investigation, but did not call them suspects.

All three men seen in the photos are black, about 20 years old and six feet tall, said police.
