A two-year-old boy who was hospitalized after a beating has died from his injuries in Louisville.

Police say the boy's aunt, Nereida Allen, and her live-in boyfriend, Joshua Peacher, assaulted him. Allen had temporary custody of the toddler.

The child was placed on life support at Kosair Children's Hospital, but died late Thursday afternoon.

Allen's assault charge has now been upgraded to murder. She's also accused of criminal abuse, marijuana possession and possession of drug paraphernalia. Peacher is charged with assault, criminal abuse, marijuana possession and possession of drug paraphernalia.

Police say Allen admitted to disciplining the boy when he threw fits. The coroner says the toddler had large amounts of bruising and showed no signs of brain activity by the time he arrived at the hospital.
