TULSA, Okla. (AP) - Police say a puppy has attacked and killed a 2-month-old boy who was left unattended in a swing.

Officer Jason Willingham said Monday the baby was mauled by the 6-week-old Labrador at the boy's home and died at the scene. He says the dog will most likely be destroyed.

Authorities have not yet released the infant's name.

Willingham says the baby's mother and grandmother were home, but nobody was in the room at the time.

Police are unsure why the dog attacked.

The child's body was taken to the Medical Examiner's office. Willingham says police will forward their investigation to the district attorney to determine whether criminal charges are warranted.
