A Colorado mother who is accused of killing two of her children and injuring a third appeared in a London court on Monday, after being arrested in the United Kingdom over the weekend. Kimberlee Singler, 35, is wanted in the United States on multiple charges, including first-degree murder, attempted murder, child abuse and assault.

How the case unfolded

The case began on Dec. 19, 2023, when Singler called 911 to report a burglary at her home in Colorado Springs, where police found two of her children, a 9-year-old girl and a 7-year-old boy, dead and a third child, an 11-year-old girl, wounded. Singler and her injured daughter were taken to a hospital for treatment.

Initially, Singler cooperated with the police investigation, but she later disappeared as the evidence pointed to her as the suspect. Police determined that the burglary report was unfounded and that Singler had killed her children and tried to kill herself and her surviving daughter.

On Dec. 26, 2023, police obtained an arrest warrant for Singler, with a $10 million bond. However, by then, Singler had already fled the country and was last seen in Colorado Springs on Dec. 23, 2023.

How Singler was caught

Singler was arrested in London on Jan. 1, 2024, by the Metropolitan Police Service, with the assistance of the FBI and the U.S. Marshals Service. She was taken into custody on an extradition warrant and appeared in Westminster Magistrates’ Court on Monday.

Singler did not enter a plea and was remanded in custody until her next hearing on Jan. 15, 2024. She faces the possibility of being extradited to the U.S. to face trial for the murder of her children.

What motivated Singler

The motive for Singler’s alleged crimes is not clear, but court documents reveal that she was involved in a bitter custody battle with her ex-husband, who is the father of the three children. Singler had filed for divorce in 2020 and had accused her ex-husband of domestic violence, substance abuse and neglect. She also claimed that he had threatened to kill her and the children.

However, her ex-husband denied the allegations and said that Singler was mentally unstable and had a history of suicidal attempts. He also said that Singler had alienated him from the children and had violated court orders regarding parenting time and communication.

The court had ordered Singler to undergo a mental health evaluation and to appear for a hearing on Aug. 7, 2023, but she failed to show up. The court also ordered her to pay $1,500 in attorney fees to her ex-husband.

How the surviving child is doing

The 11-year-old girl who survived the attack is recovering and is safe and accounted for in the Colorado Springs area, according to police. She is currently under the care of the Department of Human Services and is expected to be reunited with her father soon.

The girl suffered a gunshot wound to the head and underwent surgery at a hospital. She is reported to be in stable condition and able to communicate.
