AURORA, COLO. ? Police have recommended child abuse charges against the mother and sister of a 10-year-old boy who lost his left arm after being attacked by three pit bulls.

Gregg Jones’ mother, Renee Muniz, 37, could face felony child abuse resulting in serious bodily injury, while Gregg’s sister, Danielle Carson, 20, could face a misdemeanor charge of child abuse, Aurora police spokesman Marcus Dudley said Thursday.

“Clearly, the adult sister was responsible for the household at the time, and there is a duty on the part of the mother,” Dudley said.

Police also recommended cruelty to animals and unlawful ownership of dangerous dogs charges for both women.

The family hadn’t learned of the police recommendations, Carson told the Aurora Sentinel & Daily Sun.

Arapahoe district attorney spokeswoman Kathleen Walsh said charges likely will be filed but declined to discuss the case.

Gregg Jones was hospitalized nearly a month after the attack in his backyard Nov. 2 as he returned home from school. Gregg has undergone facial reconstruction surgery and is expected to need physical therapy.

Gregg was bitten on his head, throat, legs and arms, police said. Neighbors who heard his screams drove the dogs away with a bat and sticks.

One dog was euthanized after a police officer shot and wounded it. The other two were being held at an animal shelter along with two puppies confiscated inside the house.

Aurora recently passed an ordinance requiring pit bull owners to purchase a $200 license and comply with insurance and safety rules.
