EDMONTON, Alberta, June 15 (AP/UNB) - An early morning shooting left three dead and one in critical condition at a university campus in western Canada after an apparent armed robbery of an armored vehicle or vehicles, police said Friday.
 
Police spokesman Scott Pattison said they continue to look for the shooter or shooters after the shooting at the University of Alberta campus.  
 
"The university was quickly put into lockdown," Pattison said. "It's a crime scene, so students are required to stay in their dorms."
 
The police spokesman said no students were involved.
 
Such shootings are rare in Canada, where residents are nervous about anything that might indicate they are moving closer to their U.S. counterparts. Vancouver often has gang shootings, however, and gunfire at Toronto's most prominent mall this month left two dead and several injured.
 
Friday's shooting happened shortly after midnight in the Hub Mall area, which has student residences and shops.
 
It's the university's summer session, so fewer students are living on campus.
 
Ian Breitzke, a student, said he was watching TV when he heard a man crying out in pain. He said when police came about 10 minutes later, they broke down the door to a room behind an ATM machine and pulled out two people who looked dead.
 
The student said police then pulled out a man who was alive.
 
"The university is saddened about those who lost their lives last night and we extend our condolences to their loved ones," the university said on its website.
 
It said the rest of the campus was operating as normal.
