FBI joins hunt for mother, 35, suspected of killing her daughter, 9, son, 7, and injuring her 11-year-old daughter in Colorado

The FBI has joined the hunt for a mother accused of killing two of her young children and wounding a third.

Kimberlee Singler, 35, of Colorado Springs, Colorado, is wanted for alleged murder, attempted murder and child abuse.

Police, responding to a 911 report of a burglary at an apartment complex in the 5300 block of Palomino Ranch Point, in the city's northeast, found her and her surviving daughter, 11, lying next to the bodies of her other daughter, nine, and son, seven.

Singler and her 11-year-old daughter, both injured, were treated at the scene by emergency responders before being taken to local hospitals for further treatment.

But police said upon investigation they discovered the 911 call was a hoax.

While the young girl is still “recovering from her injuries and receiving care,” her mother is currently on the run

While the young girl is still “recovering from her injuries and receiving care,” her mother is currently on the run, a Colorado Springs Police Department spokesperson said.

She is currently 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.

A Colorado court has set bail at $10 million.

Authorities told the New York Times they had “reason to believe” that Singler, last seen on Christmas Eve, was no longer in the state.

They have cordoned off the apartment she lived in and are still investigating her disappearance.

It is currently unknown whether she went on the run alone or with someone else, nor whether there were any other parents who helped raise Singler's children.
