Colonel David Russell Williams, commander of Canadian Forces Base Trenton, pleaded guilty to all charges on October 18, 2010, after confessing to two murders and two sexual assaults, and was sentenced four days later to two concurrent life terms with no parole for 25 years.

Williams killed Corporal Marie-France Comeau, 37, a flight attendant based at Trenton, who was found dead in her home near the base in late November 2009. He also killed Jessica Lloyd, 27, who disappeared from her home outside Belleville, Ontario, on January 28, 2010. Lloyd's body was found early on February 8, 2010.

In September 2009, Williams broke into two homes near Tweed, Ontario, and sexually assaulted the women inside. Between September 2007 and November 2009, he committed 82 break-ins, most of them to steal women's and girls' underwear.

Ontario Provincial Police Detective Sergeant James Smyth began interviewing Williams at about 3 p.m. on February 7, 2010. Smyth showed him that the tread of his Pathfinder's tyres matched tracks outside Lloyd's home and that a boot print at the scene matched the boots Williams was wearing. By about 7:45 p.m., Williams had begun to confess, and he went on to describe both killings and the assaults during the roughly ten-hour interview. He was arrested the next day.

Williams was charged with two counts of first-degree murder, two of sexual assault, two of forcible confinement and 82 counts of breaking and entering. Alongside the life terms, he received two ten-year sentences for the sexual assaults, two ten-year sentences for forcible confinement and 82 one-year sentences for the break-ins, all concurrent.

On October 22, 2010, the Governor General revoked his commission and stripped his rank and decorations. On November 19, 2010, the military burned his uniform, destroyed his medals and crushed his vehicle. He was held first in segregation at Kingston Penitentiary and later moved to the maximum-security Port-Cartier Institution in Quebec.

The video is a roughly 37-minute narrated analysis by JCS - Criminal Psychology, not raw footage. Using interview-room footage, it covers the February 7, 2010 interview with Detective Sergeant Smyth from the first questions through the confession, with narration about the suspect's behavior and the detectives' technique.
