A man with ties to a convicted drug dealer killed in an execution-style shooting in Gloucester last October is no longer working for the Department of National Defence. Joey Medaglia worked with a secret security clearance - the second highest - as an administrative assistant to the Royal Canadian Navy commander, Vice-Admiral Paul Maddison, since February 2009. Medaglia is godfather to the Graham Thomas's 19-month-old twins. Thomas, 35, a convicted drug dealer who had alleged ties to the Hells Angels and the Rizzuto crime family in Montreal, was killed in a shooting at his tanning salon Oct. 26. A second man, Jason Chapman, was also shot to death. There have been no arrests. Military Police launched an investigation into Medaglia after the killing. In an email to the Citizen Tuesday, DND said Medaglia had left the department. "Mr. Medaglia no longer occupies a position with the Department of National Defence as of 27 March 2012," wrote Cmdr. Hubert Genest, director of public affairs for the navy. "While Mr. Medaglia no longer works for the Department of National Defence, he is free to apply for other jobs within the federal public service. No other information can be shared about Mr. Medaglia for privacy reasons." Medaglia handled the vice-admirals's internal and external correspondence, made entries in his calendar and processed internal files and had access to sensitive information. All top secret information was handled by employees with a higher security clearance. Security clearance reviews include routine checks, credit checks, criminal record checks and inquiries with police. Medaglia was reassigned to a new job at DND after the shooting. Thomas was arrested in 2000 and later sentenced to two-and-a-half years in prison for his role in one of the region's most prolific supply chains for cocaine and other drugs.
