The former commander of CFB Trenton pleaded guilty to the first-degree murders of Marie-France Comeau and Jessica Lloyd, as well as sexual assaults and dozens of break-ins.
Russell Williams was a senior Canadian Forces officer serving as commander of 8 Wing/CFB Trenton when police connected him to a series of crimes in eastern Ontario. The investigation ultimately established two murders, two sexual assaults with confinement and more than 80 break-and-enter and theft offences. The victims whose deaths led to the murder convictions were Corporal Marie-France Comeau and Jessica Lloyd.
Marie-France Comeau, a 38-year-old Canadian Forces corporal, was killed in November 2009. Jessica Lloyd, 27, disappeared in late January 2010 and was later confirmed murdered. Their cases became linked to Williams after investigators focused on evidence connected to the area and his movements.
Williams was arrested in February 2010. In the months that followed, prosecutors laid a large number of additional charges connected to break-ins, theft and sexual assaults. The case attracted unusual attention because the accused had held a senior command position in the Canadian military, but this archive treats that institutional status as context rather than spectacle.
On October 18, 2010, Williams pleaded guilty in Ontario Superior Court in Belleville to two counts of first-degree murder, two counts each of sexual assault and forcible confinement, and 82 break-and-enter and theft-related offences. Canada's Department of National Defence publicly acknowledged the guilty plea the same day and began the administrative steps required to remove him from military service.
Because Williams pleaded guilty, the central question of criminal responsibility did not remain unresolved. The court proceedings moved directly into sentencing after the agreed factual record was presented.
On October 21, 2010, Williams received two concurrent life sentences for the murders of Comeau and Lloyd, with no eligibility for parole for 25 years. He also received additional sentences for the sexual assaults and break-ins. The life sentences make the case clearly adjudicated for archive purposes.
Parole eligibility after 25 years is not the same as guaranteed release. It establishes the earliest point at which an application may be considered under Canadian law.
On October 22, 2010, the Governor General revoked Williams's commission and approved his release from the Canadian Forces. The Department of National Defence said he would lose his rank and medals and that his pay would be terminated and recovered from the date of arrest. The administrative release process was completed in December 2010.
That military action was separate from the civilian criminal sentence. The murder convictions and life sentences came from the Ontario court; the loss of commission and military status followed through Canadian Forces administrative authority.

The murders of Marie-France Comeau and Jessica Lloyd are solved and adjudicated. Russell Williams pleaded guilty and received two concurrent life sentences.

Williams was convicted in a civilian Ontario court. His later loss of rank, commission and military benefits was an administrative consequence and not a separate murder conviction.
