A Colorado mother, Kimberlee Singler, 37, has been extradited from the United Kingdom to the United States to face murder charges after authorities say two of her children were killed and a third was injured in December 2023.
Arrest, Extradition And Charges
Singler was arrested in London on Dec. 30, 2023. Colorado District Attorney Michael Allen said she is expected to make her first U.S. court appearance in the coming days on charges that include two counts of first-degree murder. Allen called her return to U.S. custody a "momentous day."
Allegations And Investigation
Authorities allege Singler drugged and killed her 9-year-old daughter and 7-year-old son and injured an 11-year-old daughter. Investigators reported recovering spent rounds, a blood-stained knife and empty bottles of sleeping pills from a trash can at the December 2023 crime scene. The two deceased children were found together in a bed.
Kimberlee Singler was arrested in the U.K. on Dec. 30, 2023, after police say she drugged and killed her 9-year-old daughter and 7-year-old son, and injured her 11-year-old daughter before fleeing overseas.
Initial Accounts And Subsequent Developments
Singler initially told police that a man had entered the apartment and committed the violent acts; investigators treated her as a potential victim early in the probe. One of Singler's daughters initially corroborated that account but later changed her statement. When authorities later moved to arrest Singler, she had already left the country and was later located in an upscale London neighborhood.
Extradition Fight And Legal Concerns
Both the Federal Bureau of Investigation and Colorado Springs police traveled to the U.K. to locate and detain Singler. She fought extradition, asserting concerns about the possible penalty she could face if convicted in Colorado. Her attorney argued that a mandatory sentence of life without parole for first-degree murder in Colorado could raise issues under European human rights protections. In January 2025, a U.K. judge authorized the extradition, and a later appeal was denied, clearing the way for her return to the United States.
Colorado Springs Police Chief Adrian Vasquez: "Crimes as horrific as this are simply heart-wrenching. No person, much less a child, should ever have to go through something like this."
The investigation and legal proceedings remain active as Singler prepares to appear in U.S. court on the homicide charges. The Associated Press contributed to this report.
