A London judge has rejected a U.S. mother’s challenge to be extradited to Colorado to face murder charges in the deaths of two of her young children.

The case will now be considered by the British home secretary who has the final say on some high-profile extradition cases.

A London judge on Friday rejected a U.S. mother's challenge to be extradited to Colorado to face murder charges in the deaths of two of her young children. Judge John Zani said in Westminster Magistrates Court that it would now be up to the British Home Secretary to order Kimberlee Singler returned to the United States.

A Colorado woman who fled to London after allegedly killing her two children and attacking her third is taking legal steps to prevent being extradited back to the US.
