NEWARK - The father of a 10-year-old boy fighting for his life after he was mauled by two family dogs in a Newark apartment has been charged with child endangerment.

Enrique Carrillo, 41, is being held at the city jail, according to Anthony Ambrose, the Essex County Prosecutor's chief of detectives.

The boy was left alone late Wednesday morning in an apartment on Hawkins Court with the dogs, who police believe live with the family.

Responding officers say the dogs went after them and they were forced to shoot and kill one of the dogs. Another dog was wounded. They say seven shots were fired.

The boy, who has not yet been identified by police, was taken to a local hospital in critical condition.

Ambrose says the boy also suffered minor injuries when he was struck with bullet fragments that likely occurred when the officers fired at the dogs.

"We see a lot," says Scott Crawford of the Associated Humane Society. "Even for me it was a little hard to take, especially knowing a child was involved."

Crawford says the scene was difficult to take in. "It looked like a murder scene, blood all over the apartment, blood down stairwells, both animals completely drenched," he says.

The dogs were a pit bull and an American Bull mix, authorities say. Officials say the animals bit the victim in the neck and face, tearing one of his ears off.  

Neighbors say they heard his screams and tried to help. "The kid was screaming for 45 minutes," says Sheline Snowden. "One had him by the throat, one by the arm. When cops brought him out he was dripping with blood, lifeless."

The boy has undergone surgery and remains in critical condition.
