Montreal, Canada (CNN) - Canadian police are asking for help finding 29-year-old Luka Rocco Magnotta.
He's now a suspect in a gruesome case involving a man's torso found in Montreal Tuesday.
Officials believe he knew the victim.
He also goes by the name Eric Clinton Newman.
They say they got his photo from a "very graphic website."
Authorities believe the case may be linked to one where a human hand and foot were mailed from Montreal to Ottawa.
A warrant has been issued for Magnotta's arrest.
