In a major breakthrough just before Christmas 2025, Kimberlee Singler, the Colorado mother accused of murdering her 9-year-old daughter and 7-year-old son while attempting to kill her 11-year-old daughter, has been extradited from the United Kingdom back to the United States. The 37-year-old, who fled overseas amid a bitter custody battle and staged a fake burglary, fought extradition for nearly two years but was finally returned to face multiple felony charges, including two counts of first-degree murder. As she arrives in custody on Christmas Day 2025, chilling details from the surviving child’s account and the prolonged international legal saga raise haunting questions: What drove a mother to allegedly commit such an unthinkable act that night in December 2023?

District Attorney Michael Allen called it a “momentous day,” emphasizing that justice is finally moving forward for the victims. But with Singler denying the allegations and a key witness—the now-13-year-old survivor—expected to testify, the truth behind that fatal night may prove darker than initially imagined.

The Night of Horror: A Staged Burglary Unravels

The nightmare unfolded on December 19, 2023, in Colorado Springs, when police responded to a 911 call from Singler reporting a burglary at her apartment in the Palomino Ranch Point complex. Officers arrived shortly after midnight to a gruesome scene: Singler’s 9-year-old daughter Ellie and 7-year-old son Aden dead from gunshot wounds and stabbings, her 11-year-old daughter seriously injured, and Singler herself with superficial cuts.

Initially treated as a victim, Singler claimed an intruder had attacked the family. The surviving daughter first corroborated this story. But investigators quickly grew suspicious: No footprints in the snow led to the alleged entry point, no signs of forced entry, and DNA evidence on weapons linked to Singler and the children.

By December 26, an arrest warrant was issued for Singler on charges including two counts of first-degree murder, attempted murder, child abuse, and assault. But she had vanished days earlier, fleeing to the UK where she was arrested on December 30, 2023, in London’s upscale Kensington area.

Custody Battle Turns Deadly: Motive Emerges

The killings occurred against the backdrop of an acrimonious divorce and custody dispute with ex-husband Kevin Wentz. Court orders had recently required Singler to hand over the children for holiday visitation, which she allegedly resisted. Prosecutors claim the attacks were deliberate, with evidence suggesting the children may have been drugged beforehand.

In UK court documents, prosecutors revealed chilling details from the surviving daughter’s later statement: Singler allegedly told the girl “God was telling her to do it” and that the father would take the children away. The child begged for mercy as Singler slashed her neck, but the attack continued.

Singler’s ex-husband had a solid alibi—GPS data from his work truck placed him 80 miles away in Denver.

International Fugitive: A Two-Year Extradition Fight

Singler denied harming her children and battled extradition vigorously. Her defense attorney, Edward Fitzgerald—who once represented Julian Assange—argued that Colorado’s mandatory life-without-parole sentence for first-degree murder violated European human rights laws.

A UK judge rejected the challenge in January 2025, and an appeal was denied in November. FBI and Colorado Springs police traveled to London to escort her back. On December 23, 2025, DA Allen announced her return, with Singler booked into El Paso County Jail on a no-bond hold.

Colorado Springs Police Chief Adrian Vasquez called the extradition a “significant milestone,” describing the alleged acts as “unthinkable” and “reprehensible.”

Who Is Kimberlee Singler?

Singler, then 35 at the time of the incident, was in the midst of a contentious separation after marrying Wentz in 2018. Described in court filings as blaming her ex for framing her, she had previously accused him of dreaming about killing the family.

The surviving daughter, now 13, suffered significant injuries but recovered physically. DA Allen confirmed she is expected to be a central witness, though he declined further comment on the case details.

Charges and Next Steps: Justice on the Horizon

Singler faces:

Two counts of first-degree murder (after deliberation and intent)
Two counts of first-degree murder (victim under 12)
One count of attempted first-degree murder
Three counts of child abuse
One count of assault

Her first court appearance is imminent, with a preliminary hearing likely within 30 days to determine if the case proceeds to trial.

Allen stressed this is “just the first step” in seeking justice, noting international extraditions can drag on for over a decade—this one resolved in under two years thanks to multi-agency cooperation.

Lingering Questions: A Darker Truth?

While authorities maintain the burglary was staged and point to the custody dispute as motive, Singler continues to deny involvement. Her UK team claimed the surviving child’s statement may have been coerced.

Online speculation has swirled for years, but officials urge focusing on evidence. The surviving child’s testimony could prove pivotal in unveiling what truly happened after the 911 call that night.

As families gather for Christmas 2025, the Wentz family faces another holiday shadowed by loss. “You can run, but we will find you,” Chief Vasquez said, echoing the resolve that brought Singler back.

The case now shifts to Colorado courts, where answers—and potentially a darker reality—may finally emerge.
