Deputies say a Palmetto woman failed to report child abuse that left her grandson dead.

Karla Kay Gray, 52, is facing charges of failure to report child abuse in connection with the death of her grandson, 4-year-old Alexander Marr.

According to the Manatee County Sheriff's Office, deputies responded to 708 59th Ave. Terrace W in Bradenton on April 12 after receiving a call about an unresponsive child.

The child, identified as Alexander, was pronounced dead at the scene. Deputies say an autopsy found Alexander suffered injuries consistent with child abuse.

Deputies said the boy lived with his mother, 32-year-old Dianna Marr, and the mother's boyfriend, 24-year-old Trevor Cardarelle. Cardarelle was arrested April 12 for violation of probation and possession of a firearm by a convicted felon. He remains in the Manatee County Jail.

Deputies did not say who they believed caused the injuries that killed Alexander.

The investigation continues, and deputies say additional arrests are pending.
