David Russell Williams (born March 7, 1963) is a former colonel of the Canadian Armed Forces and convicted double-murderer who was sentenced to life imprisonment in 2010.In late January 2010, the Ontario Provincial Police (OPP) discovered evidence that led them to suspect Williams' involvement in the disappearance and death of Jessica Lloyd, and suspected links to two other crimes that had been committed in close proximity to other locations near Williams' previous home in Tweed, Ontario. On February 7, Williams was interrogated on video by OPP investigator Jim Smyth and confronted with the evidence of tire tracks and boot prints at Lloyd's home. Over the next 10 hours, Williams gave a detailed confession of the sexual assault and murder of Lloyd, and also the sexual assault and murder of Corporal Marie-France Comeau and at least two other cases initially.The subsequent investigation into Williams brought further confessions and revealed evidence of detailed notes and photographs stored at his home. The evidence showed he had broken into at least 82 houses to steal underwear of females, including children. This behaviour later escalated to sexual assaults and later still to the rapes and murders. He was charged with two counts of first-degree murder, two counts of forcible confinement, two counts of breaking and entering, and sexual assault. Another 82 charges relating to breaking and entering were later added.
