Colorado Springs Police Search for Mother in Death of Two Children

The police are searching for a 35-year-old woman charged with murdering two of her children, ages 9 and 7, and injuring a third, age 11, at an apartment in Colorado Springs, Colo., last week, the authorities said Thursday.

The woman, Kimberlee Singler, was found injured together with the three children in the early hours of Dec. 19, after the authorities received a report of a burglary at the apartment in the city’s northeast, the Colorado Springs Police Department said in a statement.

Ms. Singler and her 11-year-old daughter, both injured, were treated at the apartment by emergency medical workers before being transported to local hospitals for further treatment, the police said. They would not provide additional information about the nature of the injuries or the cause of death of the 9-year-old girl and 7-year-old boy, pending Ms. Singler’s arrest.

The injured 11-year-old was “recovering from her injuries and being cared for,” Ira Cronin, a spokesman for the Police Department, said in a phone interview on Thursday. As the investigation unfolded, the police “determined that the information of a reported burglary was unfounded,” he said.

On Tuesday, investigators issued an arrest warrant for Ms. Singler, who was last seen on Saturday, though the police would not specify where. She is wanted on four counts of first-degree murder, two counts of attempted first-degree murder, three counts of child abuse and one count of assault. The court has set a $10 million bond.

Mr. Cronin said that the F.B.I. was also involved in trying to find Ms. Singler. “We have reason to believe she may not be in the state,” he said.

The F.B.I. did not immediately respond to a request for comment on Thursday evening.
