Former Colonel Russell Williams is pictured during transfer of command of 8 Wing/CFB Trenton July 15, 2009. The one-time commander of the Trenton air base was sent to Kingston Penitentiary after four days of shocking testimony in a Belleville, Ont., court where he pleaded guilty to a series of burglaries, sex assaults and the brutal sex slayings of Marie-France Comeau , 37, who served under his command, and Jessica Lloyd, 27. Like Paul Bernardo, the former air force colonel is held in the Lower H segregated range, away from the rest of the prison population.MCpl Tom Trainor
