A police official in northwestern New Mexico says an 8-year-old boy who died after being mauled by dogs was found face-down and unresponsive by his mother. Cibola County Undersheriff Tony Mace says Sunday that one of the nine dogs euthanized after the attack belonged to boy's family and was reported to have bitten the child on a previous occasion.
Tomas Jay Henio died Wednesday near his family's home in Pine Hill.
The family dog and eight strays were euthanized.
The sheriff's office played an assisting role in the case by sending an animal control officer to round up the dogs and isn't investigating the child's death.
The FBI was investigating the death because the attack happened on Navajo Nation land.
The federal agency didn't return a phone call seeking Sunday.
