A Colorado woman accused of murdering her two young children has lost her legal battle to remain in the United Kingdom. A UK judge ruled that Kimberlee Singler can be extradited to the United States to face trial for the alleged killings of her 9-year-old daughter and 7-year-old son, and the attempted murder of her 11-year-old daughter. Singler, 36, fled to the UK following the incident in December 2023.

Singler faces charges including four counts of first-degree murder, two counts of attempted first-degree murder, and multiple counts of child abuse and assault. Her legal team, led by Edward Fitzgerald KC, argued that extradition would breach the European Convention of Human Rights due to the potential for a life sentence without parole in the US. However, Judge John Zani rejected this argument. The final decision on extradition now rests with UK Home Secretary Yvette Cooper.

During the extradition hearings, the US legal team, represented by Joel Smith KC, presented details of the alleged crimes. They asserted that Singler shot and stabbed her two younger children and attacked her eldest daughter with a knife during a custody dispute with her husband. Colorado authorities discovered spent shell casings, a bloodstained knife, and empty pill bottles at the crime scene. The surviving child reportedly told investigators that Singler instructed all three children to close their eyes before the attacks.

Smith argued that while a life sentence without parole is a possibility, the governor of Colorado retains the power to grant clemency. Fitzgerald countered by highlighting the stark difference in the number of individuals serving such sentences in the UK compared to the US, emphasizing the severity of the potential punishment. The case has drawn significant attention due to the nature of the alleged crimes and the international legal battle surrounding the extradition process.
