TULSA — A 2-month-old baby who was mauled by a puppy died from multiple dog bites, according to an autopsy report released Friday by the state medical examiner’s office.

The 11-page autopsy report on Zane Alan Earles states the infant died from multiple soft tissue injuries due to dog bites.

"There is nothing in the autopsy to indicate the infant was dead prior to when he was attacked by the dog,” said Cherokee Ballard, medical examiner’s spokeswoman.

The autopsy lists the July 28 death as "violent, unusual or unnatural” by means of a dog. Most of the skin and soft tissue of the left groin, left lower buttock and left thigh were missing, and there were contusions to the abdomen, the report stated.

The autopsy report stated tissue from the baby’s body was found in the dog’s stomach. The black Lab mix was euthanized.

No traces of drugs or alcohol were found in the body, according to the toxicology report.

Linzy Earles, the baby’s mother, who was 17 at the time of his death, tested positive for drug use the next day but told police she smoked marijuana after her baby died, according to records released in November by the state Office of Juvenile Affairs.

Earles, 18, was charged in November with second-degree manslaughter in the Tulsa County District Court’s juvenile division. Because of the juvenile filing, the status of her case is confidential.

She is accused of leaving her son unsupervised.
