HILLSBOROUGH COUNTY, Fla. — A Hillsborough man who told detectives he forcefully picked up a 16-day-old baby in his care after the baby woke him up now faces a murder charge, after an autopsy report confirmed the baby died from injuries sustained in the incident.

Aaron James Bordelon, 29, was initially charged with aggravated child abuse, aggravated battery with great bodily harm, and child neglect with great bodily harm. 

He told deputies he became agitated when the child woke him up so soon after a recent feeding.  He said he forcefully picked up the baby, admitting "this is my fault."

After that Bordelon said he noticed the baby's physical condition deteriorated.  The child began to breathe slowly and had bruising under his eyes and on his eyelids. 

Deputies said Bordelon did not seek medical attention until after the baby's mother arrived.  They then took the child to Brandon Regional Hospital using the Lyft ride share service. 

During the ride, deputies said Bordelon tried to conceal the bruising with makeup, but the mother removed it before arriving at the Emergency Room. 

The child died on Tuesday.

Bordelon remains in the Falkenburg Road Jail. Charges against him were upgraded to one count of First-Degree Murder with Great Bodily Harm or Death of a Child.
