A Colorado Springs woman accused of drugging and killing two of her children in December 2023 will be sent back to the United States after a judge in London ruled in favor of her extradition, according to NBC London.

Kimberlee Singler was arrested in the United Kingdom on Dec. 30, 2023, just 11 days after Colorado Springs Police responded to a burglary call at her home.

CSPD found Singler and her 11-year-old daughter with injuries, and her 9-year-old girl and a 7-year-old boy dead. On Dec. 26, 2023, police obtained an arrest warrant for Singler on suspicion of first-degree murder, attempted first-degree murder, child abuse and first-degree assault.

Singler has been fighting extradition back to the U.S. while in U.K. territory, with her representation claiming that sending Singler back to the U.S. would breach Article 3 of the European Convention of Human Rights.

In Singler’s court appearance Thursday morning, her representation claimed that there were flaws in the investigation by Colorado Springs Police, including the claim that her daughter’s witness statement was non-voluntary.

Despite Singler’s arguments, the judge ruled in favor of the extradition. It is unclear when she will be extradited to the U.S.
