A Colorado woman accused of killing her two young children lost her bid to avoid life in prison in the United States after a United Kingdom judge ruled that she can be extradited to the states for trial, according to Reuters.

U.K. authorities took Kimberlee Singler into custody on Dec. 30, 2023 after she was accused by Colorado authorities of drugging and killing her 9-year-old daughter and 7-year-old son, and injuring her 11-year-old daughter before she allegedly fled overseas.

Her attorney, Edward Fitzgerald, Kings Counsel (KC), who also represented Wikileaks co-founder Julian Assange, argued that extraditing Singler to the U.S. would violate the European Convention of Human Rights, because she would not be eligible for parole if convicted, according to NBC News affiliate KOAA.

Smith argued in September that a governor could eventually grant Singler clemency if she is convicted and sentenced to life without the possibility of parole.

Fitzgerald, meanwhile, said life sentences without the possibility of parole in the U.K. are “totally alien to us.” There were 63 people serving life sentences in the U.K. two months ago, whereas the U.S. had 49,000 people serving life sentences, Smith said, according to NBC.
