Four people have been indicted in the death of a 6-year-old boy in northern Arizona last June.

Prosecutors say Jason Hester weighed just 29 pounds and showed signs of dehydration, multiple bruises and abrasions at his autopsy by the Coconino County Medical Examiner's Office.

The official cause of death was undetermined, but authorities say there were multiple findings suspicious of child neglect.

The boy was found unresponsive in the Ashfork-area home of his 37-year-old aunt and primary caretaker June 22. He later was pronounced dead at a Flagstaff hospital.

A county grand jury indicted Lillian Hester on first-degree murder and child abuse charges and the boy's maternal grandmother, 64-year-old Lenda Hester, on negligent homicide and child abuse.

The two women's boyfriends also were indicted on negligent homicide and child abuse.
