A nine-year-old California boy is dead after he was mauled by his sister's three pit bulls.

Tyler Trammell-Huston was found unresponsive Sunday by his half-sister, who had left him alone for three hours while she went to work, according to Fox40.

The tragedy happened in the community of Linda, Calif.

Alexandria Griffin-Heady told the outlet she never thought her three dogs would attack him.

"He loved them, he laid in the bed with them. He played with them. He wanted one of their puppies," she said.

"I failed him, whether it's my fault, my dogs' fault, whoever's fault. I wanted to protect him, and I wanted to give him an amazing life."

Alexandria Griffin-Heady told Fox40 she "failed" her brother who was mauled to death by her dogs.

Trammell-Huston's uncle Donald Thorpe told CBS Sacramento that the boy had moved in and out of foster homes after his mother died of a drug overdose, and that Griffin-Heady had been allowed to keep Tyler for weekend visits. She eventually wanted to adopt him.

But he said he doesn't think that the 24-year-old was mature enough.

The boy's aunt also said she thought that his sister's living conditions and dogs made it inappropriate for him to live with her.

“She was trying to rescue him from the system,” Laura Badeker told the Sacramento Bee.

“But I told everyone on the team that was supposed to be protecting Tyler that Ali was not prepared to take care of him on any level. They were warned, over and over again."

Investigators will decide by the end of this week whether or not to lay charges, according to the Associated Press.

Griffin-Heady's lawyer told the Sacramento Bee that it was basically an accident, and that charges wouldn't make sense.

The dogs, which are now in an animal shelter, will be put down if they are found to be dangerous animals, according to Yuba County Undersheriff Jerry Read.
