A U.K. judge has cleared the way for the extradition of Kimberlee Singler, a Colorado mother accused of murdering her two young children, as she lost her legal battle against being sent back to the U.S. to face charges. The London court rejected her challenge to extradition, allowing U.S. authorities to proceed with her return to Colorado Springs. Singler faces serious allegations involving the drugging and killing of her children. The ruling marks a significant step in the legal proceedings surrounding this tragic case.
