An inmate at the Edmonton Institution found stabbed in his cell Saturday night has been identified as Gyozo Victor Barasso, 45.

An autopsy conducted Monday determined Barasso died from multiple stab wounds.

Guards responded to an emergency call activated from within the inmate's single accommodation cell when they found Barasso in medical distress, said Rick Dyhm, a manager at the maximum security prison.

Guards administered CPR, but the inmate later died.

Barasso was serving four years and two months on convictions of robbery, assault with a weapon, assault causing bodily harm and possession of a weapon for a dangerous purpose.

According to parole documents, Barasso was released to a halfway house last summer and left without permission after one week.

He was arrested and charged ten days later in connection with robberies at three pharmacies, which prompted police to call him the "drug store bandit." 

The documents state Barasso had a history of becoming violent with corrections officers and other offenders when he didn't get his way or thought he had been slighted.

Edmonton Institution remains on lockdown until prison officials decide it is safe to resume normal operations, Dyhm said. All visits for inmates have been cancelled until further notice.

Edmonton police are investigating the death, which has been ruled a homicide.

Correctional Service of Canada is also reviewing the circumstances surrounding the stabbing.
