A Colorado woman is being sought on suspicion of killing her two young children and wounding a third, US authorities said.

Kimberlee Singler, 35, of Colorado Springs is wanted on an arrest warrant alleging murder, attempted murder and child abuse, according to a statement from the city.

Colorado Springs police answered a 911 call reporting a burglary at an apartment complex early on December 19 and found the bodies of Singler's nine-year-old daughter and seven-year-old son, the statement said.

Singler was found injured along with her 11-year-old daughter. They were taken to local hospitals for treatment, the statement said.

“As the investigation into this case unfolded, it was determined the initial report of a burglary was unfounded,” the statement said.
