An American woman accused of murdering two of her children has been extradited from the United Kingdom to face justice in the United States. The extradition follows a lengthy legal battle after her arrest in an upscale London neighbourhood.
From Colorado to Kensington: The Timeline of a Tragedy
Kimberlee Singler, 37, was arrested by the UK's National Crime Agency in Kensington, west London, on 30 December 2023. This occurred just a week after the bodies of her nine-year-old daughter and seven-year-old son were discovered in their family home in Colorado Springs, USA, on 19 December 2023.
Her 11-year-old daughter was also injured in the incident but survived. Singler herself was found with superficial knife wounds and initially told police that an intruder had entered the apartment and attacked the family. The surviving child initially supported this story but later told an investigator that her mother had said "God made her do it," according to UK court documents.
A Failed Extradition Challenge and Custody Dispute
Singler fought her extradition to the US, with her London defence barrister, Edward Fitzgerald KC, arguing that a potential life sentence without parole in Colorado would breach European human rights law. Fitzgerald, who also represented Julian Assange, saw the challenge rejected by a judge in January 2025, and a subsequent appeal bid was denied in November.
The case is deeply entwined with a bitter custody dispute. The day before the children's bodies were found, a Colorado judge had ordered Singler to comply with a previous order to allow the children's father to take custody for the holidays. She was instructed to either hand them over or bring them to a court hearing on 20 December 2023.
On the day of that hearing, Singler filed a motion to delay it, writing that she and her children had been attacked and two were murdered. She requested time to grieve. Police, however, found no evidence of an intruder, reporting no footprints in the snow leading to the patio door she claimed was used. GPS evidence also placed the children's father roughly 80 miles away at the time.
Charges and Next Steps
Singler now faces a series of serious charges in Colorado, including:
- Two counts of first-degree murder
- One count of attempted murder
- Three counts of child abuse
- One count of assault
According to the court clerk's office, she does not yet have a US-based attorney listed as representing her in the official documents. Her extradition marks the next chapter in a transatlantic case that has shocked communities on both sides of the Atlantic.
