Croitoru is better known by his ring names, Johnny K-9 and Bruiser Bedlam. He competed in several Canadian wrestling promotions, including Stampede Wrestling, and later wrestled for New Japan Pro Wrestling, Smoky Mountain Wrestling, and the World Wrestling Federation (WWF).
In 2005, Croitoru was arrested for the murder of lawyer Lynn Gilbank and her husband Fred. After a lengthy investigation, the charges were dropped in June 2006 because of insufficient evidence. He worked as a security guard in Vancouver, British Columbia until being arrested in May 2009 for conspiracy to commit murder.
On January 24, 2011, Croitoru was charged with first degree murder in connection with the 2008 execution of Jonathan Barber in Burnaby, British Columbia.
