A Huxley woman has been arrested and charged with two counts of first-degree murder in the deaths of two newborn twin daughters.

Jackie Nichole Burkle, 22, is facing charges of two counts of first degree murder, a class A felony, that is punishable to life in prison for each count if convicted.

Police said Burkle told them she killed the twin girls around 7:30 a.m. Friday.

The investigation began after one of Burkle’s co-workers expressed concern to police about noticing Burkle had appeared pregnant one day and then suddenly appeared to not be pregnant two days later. The report said Burkle’s co-worker said she was concerned about the location of the child’s whereabouts.

According to the complaint and affidavit filed for the case, Burkle admitted to killing the children and later told authorities they could find the bodies in the trunk of her vehicle. Burkle was arrested Tuesday afternoon.

Burkle is currently being held at the Story County Jail on $500,000 bail for each count.

A preliminary hearing has been set for Jan. 20.
