SAINTE-ANNE-DES-PLAINES, Que. — Correctional Service Canada says an 85-year-old convicted killer has escaped from a minimum-security prison north of Montreal.

Officials say Ricardo Vilches was not present during the noon head count Monday at the Archambault Institution in Ste-Anne-des-Plaines, Que.

Prison officials say an arrest warrant has been issued for Vilches and Quebec provincial police have been notified.

Vilches is currently serving an indeterminate sentence for second-degree murder.

He is about 5-foot-6 and weighs about 170 pounds, with a medium complexion, brown eyes, grey hair and a scar on his nose.

Corrections officials say they will investigate the circumstances surrounding Vilches’ escape.
