Jodey Lynn Pruitt

Jodey Lynn Pruitt. Charleston County Sheriff's Office/Provided

A 3-month-old boy died in a hospital Sunday as his mother sat behind bars, accused of the abuse that killed him.

North Charleston police upgraded the original charge against 22-year-old Jodey Lynn Pruitt from inflicting great bodily injury upon a child to murder.

Pruitt has remained in custody since officers escorted her from Medical University Hospital when the infant was admitted Nov. 22.

After a week of treatment, Alexander Conegobanda died of head trauma early Sunday morning, according to the Charleston County coroner.

Police say Pruitt hurt the boy at her home on Dorchester Road.
