Detailed information is coming to light in a murder case that shocked the Front Range just before the holidays and remains a curiosity. Little information has been released in the ongoing investigation, which has an international twist.

Kimberlee Singler, 35, is awaiting extradition from the United Kingdom, arrested and accused of killing two of her children and injuring a third. 

She and her ex-husband were experiencing a contentious divorce and custody battle after their April 2018 split. Singler had missed a date to drop off the children at a police department for their father’s scheduled visitation on Dec. 16 and was facing several motions to comply with the order. 

In divorce documents obtained by The Gazette, the Colorado Springs mother described her injuries in a motion filed two days after the attack.

In the Dec. 20 court document, Singler explained why she could not make a scheduled in-person court hearing in Larimer County. 

In the motion, she said that she needed time to grieve and therefore was unable to make it to the hearing. 

Two days earlier, on the day of the alleged attack, a clerk with the Larimer County Court left Singler a voicemail telling her that she and her children were ordered to appear in court Dec. 20 if she was unable to exchange the children with her ex-husband, Kevin Wentz, before then.

In the document she wrote asking for a continuance, Singler claimed to have also been injured in the alleged fatal break-in. “I am unable to attend in person/ virtually/ or otherwise, because I have lacerations on my neck and wrists,” she wrote.

Singler told the courts that she was writing from a library computer because her home was locked down and she had no access to a phone or laptop. 

In the official request for a continuation, she informed the courts that she needed to delay the hearing because she was weak and grieving the loss of her two children.

“Someone broke into my residence at 11 am and attacked the children and myself,” she explained. Singler said that she was weak and would be unable to attend a hearing for at least another 10 days.

It is the first inkling of her possible defense in the troubling case since the murders occurred. 

In the document, she explained that a burglar entered her home before noon on Dec. 18, killed two of her children and left her and a third child to die. “But we survived,” she said. Singler explained that she was not able to call 911 until the morning of Dec. 19, just after midnight.

Three days later, police said, was the last time Singler was seen in the United States. On Dec. 26, investigators issued a warrant for her arrest and on Dec. 30, she was taken into custody in London.

Another court document contends that Singler actually told police that her ex-husband was a suspect in the break-in and murders of their own children. 

In a Jan. 2, 2024, court request made by Wentz, the childrens’ father indicated that Singler tagged him as the intruder in their home that morning, but, according to the document, investigators determined that Wentz “was not involved in the childrens’ murder.”

The document was a request by Wentz to release a Child and Family Investigative report.

Details that would normally be found in a police affidavit, such as how police determined it was not a burglary, are not available because the document was immediately sealed when it was signed, Colorado Springs police spokesman Ira Cronin said.  

Singler is in custody in the United Kingdom and is scheduled for a court date Monday. The 4th Judicial District is requesting that she be extradited to Colorado on 10 charges including two counts of first-degree murder and one count of attempted first-degree murder in relation to the couple’s three children. 

Legal experts said not to expect for Singler to be extradited for months because the process is a long one. “This is just red tape,” said University of Denver associate law professor Ian Farrell. “I imagine there are I’s to be dotted and T’s to be crossed. They have to make sure everything is in order before they hand someone over.”
