A Colorado woman who stands accused of murdering her two children before fleeing to the United Kingdom has been returned to American authorities and will now face justice. Kimberlee Singler, 37, was arrested by authorities in London in December 2023, little over a week after her children were found dead inside their Colorado Springs home. Singler had been embroiled in a bitter custody battle at the time she allegedly killed her 7-year-old son, Aden Wentz, and her 9-year-old daughter, Elianna Wentz.
