Blood discovered on a weapon used in the tragic deaths of two children in Colorado has been identified as belonging to their mother, Kimberlee Singler. She was recently extradited after evading capture by fleeing to the UK.

As detailed in an affidavit accessed by KKTV 11, investigators from Colorado Springs concluded that the blood found on the firearm used in the December 2023 killings matched Singler’s DNA just days after the incident.

While one of the children suffered a throat laceration, autopsies revealed that both children died from gunshot wounds.

Authorities apprehended Singler in London on December 30, 2023, more than a week following the discovery of her children’s bodies, Elianna Wentz, aged 6, and Aden Wentz, aged 7, as noted by CrimeOnline.

Singler and her 11-year-old daughter sustained injuries, with Singler allegedly claiming they were victims of a home invasion. However, police found no evidence of forced entry into their residence.

Initially, Singler accused her ex-husband of the attack, but investigators quickly suspected her involvement. The ex-husband was cleared of suspicion due to a solid alibi, as he was driving a GPS-monitored vehicle at the time.

The ex told investigators that he had suspicions about Singler, and although he could not recall her threatening the children, she had told him that he wouldn’t see them again. Singler’s statement reportedly happened during an ongoing custody dispute during the 2023 summer.

Further, the 11-year-old, who initially lied about the incident at her mother’s request, reportedly identified Singler as her attacker. The victim then said, “she had been feeling awful about the lie,” according to Law&Crime.

Singler claimed she had been sleeping on her couch when the attacks occurred, and that she woke up to a male grabbing. She claimed she then fainted and woke up to find the children dead.

She told investigators she had been too weak to call 911 for assistance, but eventually called for assistance when she found her phone, after it “randomly started playing music.”

Autopsies confirmed that the children also had toxic levels of sleeping aids in the system, according to the affidavit.

Shortly after the attacks, Singler fled the country. She fought extradition, arguing that sending her back would subject her to a potential life sentence in violation of the European Convention of Human Rights.

A British judge disagreed and, in November, ordered Singler to return to the U.S.

Singler is charged with murder, attempted murder, assault, and child abuse. She remains behind bars without bond.
