LONGMONT, Colo. -- Court documents say a Colorado woman accused of cutting open the belly of a pregnant woman and removing her unborn baby had told her own family that she was pregnant.

The documents obtained Thursday say suspect Dynel Lane asked her husband to accompany her to a pre-natal appointment on Wednesday.

However, when he came home to meet her, the documents say she reported having a miscarriage and showed him a baby gasping for breath in a bathtub.

The baby did not survive. The child's mother is expected to recover.

Lane was arrested on suspicion of attempted first-degree murder and other charges.

A doctor told investigators the incision in the mother's belly was well performed and would have required some research.
