A woman from Colorado Springs accused of killing two of her children and attempting to kill a third has been arrested in the UK.
An arrest warrant was issued for Kimberlee Singler on murder and attempted murder charges after her seven-year-old son and nine-year-old daughter were found dead in the home. Her 11-year-old daughter was sent to the hospital to be treated for injuries, the Colorado Springs Police Department said.
The department's Violent Offender Fugitive Task Force had been searching for Singler, 35, since the warrant was issued Tuesday, police said. The FBI assisted the search, a public affairs officer with the FBI's Denver office told CNN.

Officers initially responded to Singler's home shortly after midnight on December 19 after receiving a 911 call about a burglary. The call came from inside the home, public information officer Ira Cronin told CNN, though he could not confirm who made the call.
"Officers arrived on the scene and observed an adult female and an 11-year-old female who had sustained injuries," CSPD said in the news release. "Two other juveniles, a nine-year-old girl and a seven-year-old boy, were found deceased in the residence."
The mother and her surviving daughter were taken to a hospital, Cronin said.
Singler was originally considered a victim, based on the initial burglary report, but she became a suspect "over the course of the investigation," Cronin said. "Until we had probable cause we weren't able to hold her for any reason."

The burglary was later determined to be "unfounded," according to the release.
Singler was initially co-operating with police after her release from the hospital. At some point, she became unco-operative and police were unable to get in contact with her, Cronin said.

Singler was last seen on December 23. She faces four counts of first-degree murder and two counts of attempted murder. The charges for each alleged crime were doubled due to the children all being under the age of 12.
Singler's bond was set at $US10 million ($14.6 million).
"The details of the arrest warrant are currently sealed under court order and are expected to be unsealed at a later time," police said in the release.
