Authorities have arrested the parents of an 18-month-old North Texas toddler who was mauled after he crawled through a doggie door into the backyard where the family's dogs attacked him.
Twenty-six-year-old Chance Walker Sr. and 23-year-old Patricia Walker were being held in the Tarrant County Jail on injury to a child charges.
Tarrant County Sheriff's spokesman Terry Grisham says the Walkers were taken into custody Thursday.
An arrest warrant affidavit says the boy's parents, who were sleeping, knew their son could get out of his playpen and that the dogs were aggressive and had harmed people in the past.
The affidavit shows Tarrant County deputies were called to the home six times because of the dogs.
Doctors at Cook Children's Medical Center had to reattach the toddler's right ear and his face was severely disfigured in the Jan. 30 attack. The affidavit also said he received around 400 stitches.
The affidavit says Patricia Walker tested positive for methamphetamine the day after the attack, while Chance Walker, Sr. refused to take a drug test.
If convicted, the parents could face up to 20 years in prison. Their bond is set at $100,000 each. Online jail records do not show that they have an attorney.
Their son remains in foster care since his release from the hospital. A custody hearing is set for 8:30 a.m. Friday.
