A Casper woman is accused of breaking her baby's arm.

Twenty year old Kelsey Steed has pleaded not guilty to one charge of aggravated child abuse.

Investigators with the Casper Police Department say in August 2014, Steed took her then eight month old daughter to the hospital, because the baby could not move her right arm.

Hospital employees suspected the injuries were caused by abuse and contacted law enforcement.

A doctor told police that there were four different fractures and each one happened at different times, because they were in different stages of healing.

The doctor added that a great deal of force was needed to break the bones.

When interviewed, Steed admitted that got frustrated with the baby on the morning of the hospital visit, saying she was stressed out and frustrated that the baby woke her up at 2 AM.

She also said she had been rough with the child, but added she did not intentionally hurt the baby.

Investigators also learned that the baby had been at the hospital two months prior for a torn esophagus, and was flown by helicopter to Children's Hospital in Denver, but the cause of that injury had not been determined.

Steed is being held on $5,000 bond awaiting trial, and could face up to 25 years in prison if convicted.
