On December 18, 2023, Kimberlee Singler allegedly killed her two children — seven-year-old Aden Wentz and nine-year-old Elianna "Ellie" Wentz — by shooting them in the head and stabbing them in the neck at their home in the Stetson Hills area of Colorado Springs, Colorado. Their 11-year-old sister sustained a significant injury but survived. Singler was also found injured. The killings occurred amid a contentious custody dispute between Singler and the children's father, Kevin Wentz, on the same day the court granted an emergency motion to enforce the father's parenting time and two days before Singler was ordered to appear in court with the children. Singler initially reported a false burglary and was treated as a witness and victim, allowing her to leave the hospital. She subsequently fled to the United Kingdom, where she was arrested in London. After a prolonged extradition process, she was returned to the United States in December 2025 to face seven felony charges including first-degree murder.

The Fox21 article describes her as "the mother accused of murdering her two children." The USA Today article states: "Singler faces seven counts, including the first-degree murders of her 9-year-old daughter and 7-year-old son in December 2023." Prosecutors alleged she killed the children by shooting and stabbing them.

The Fox21 article states: "a warrant for Singler's arrest was issued on Dec. 26, accompanied by charges including multiple counts of murder, child abuse, and attempted murder." The USA Today article confirms: "Singler was arrested in London just over a week after two of her young children were discovered dead" and that she was returned to the United States on Dec. 23, 2025 and is being held in custody.

Notable Details
Several notable systemic and procedural details emerge from the sources. First, the murders occurred on Dec. 18, the same day the court granted Wentz's Emergency Motion for Law Enforcement Assistance to Enforce Parenting Time, and just two days before Singler and the children were ordered to appear in court (Fox21). Second, Singler initially reported a burglary, which was later "determined" to be "unfounded" (NYT, USA Today). Third, the USA Today article states Singler was initially considered "a witness and a victim and allowed her to leave the hospital as there was not enough probable cause to suggest she was linked to the children's deaths." She then disappeared and fled to the United Kingdom, where she was arrested in London. Fourth, Singler challenged her extradition on human rights grounds, arguing a mandatory life-without-parole sentence would breach her rights; a UK judge dismissed this challenge (USA Today). She was not returned to the US until approximately two years later in December 2025. These details reveal potential systemic gaps, particularly that the suspect was allowed to leave the hospital and subsequently flee the country, and the significant timing of the murders relative to court proceedings.
