A Casper man is now admitting that he shook a baby.

Twenty-seven year old Phillip Hall has pleaded guilty to one reduced charge of child abuse (originally aggravated child abuse).

Police investigators say in middle February, they were called to the Wyoming Medical Center, and were advised an infant was in the emergency room with injuries consistent with being violently shaken.

Hall, who had been babysitting, took the infant to the hospital, and told a nurse he was carrying the baby, when he fell and the infant hit her head on the floor.

Further examination by a doctor, showed the injuries were more consistent with a concussion and there was no bruising to the exterior of the baby's skull.

The infant was life flighted to Children's Hospital in Colorado.

Investigators searched the house on Boxelder Avenue where the incident occurred and determined that Hall's fall story did not check out.

When interviewed a second time, Hall admitted to shaking the infant to get her to stop crying.

He used a doll to demonstrate to police what he did, and said he shook the infant harder than he should have, and made up the fall story.

As part of a plea deal, prosecutors will not seek any prison time for Hall, and might seek first time offender status, which means if he completes a term of probation, the conviction would be cleared from his record.

Hall is free on a $10,000 PR bond and will be sentenced at a later date.
