Colorado mother suspected in deaths of 2 of her children is arrested in U.K.

A Colorado woman suspected of killing two of her children was apprehended in the United Kingdom this weekend, Colorado Springs police said.

U.K. authorities took Kimberlee Singler, 35, into custody without incident, Colorado Springs police said late Sunday. Details, including the location of the apprehension, were pending, the police department said.

“Detectives with the Colorado Springs Police Department’s homicide unit continue to work closely with multiple law enforcement agencies in pursuing the ongoing investigation,” it said.

On Monday, Singler made an initial appearance in Westminster Magistrates’ Court in London, according to The Associated Press. Singler is facing extradition to the U.S. but details of that process are pending, according to The Associated Press.

Singler was named in an arrest warrant that alleges she committed murder, attempted murder, child abuse and assault, according to police. She was last seen Dec. 23, Colorado Springs police said.

On Dec. 19, officers responding to an early morning 911 call about a burglary at Singler’s condo unit found a girl, 9, and a boy, 7, dead at the scene, police said.

Singler and an 11-year-old daughter were hospitalized, they said.

Investigators came to believe that the claim of burglary was unfounded, and the arrest warrant was obtained, police said.

The suspect and her estranged husband have been locked in a contentious, yearslong divorce case, according to court records.
