Wise County Sheriff Lane Akin told The Dallas Morning News that deputies found the children while responding to a domestic disturbance call near Rhome, about 32 kilometres north of Fort Worth.
According to a WFAA report, authorities in Wise County received a call at about 7:20 a.m. on February 12 about a violent incident involving a man and a woman at a house off County Road 4930 near Newark, located about 30 miles north of Fort Worth. When they investigated, Akin said, deputies found two children locked together inside a dog kennel.
Johnson said food was kept just out of reach of the children in a refrigerator that had three straps on it to lock it.
The children, who range in age from 1 to 5 years, were taken to Cook Children's Medical Center in Fort Worth for medical evaluation.
One Texas Sherriff said it was the worst case of child abuse they had ever seen. They were arrested and each charged with four counts of child endangerment.
Neighbors told KXAS they noticed the couple begin to use the building a couple of weeks earlier, but had no idea that there were children living inside.
"I've not worked [a case] where children are locked inside a dog kennel, and I find that absolutely disgusting", he said.Harkings was also charged with assault.
The Rhome incident recalls a case in August 2017 when police said a Missouri couple had locked four children inside makeshift boxes made out of plywood and screws inside a home.
Fabila had to be taken to the hospital for wounds on his face before being charged but was taken to jail after his treatment. The man had cuts to his face.
She said the children were being evaluated at the hospital and for the time being were not in state custody.
"You'd think that being right across the street we would know something". Deputies found a 24-year-old man and woman at the home when they arrived. But you don't know.
Marissa Gonzales, a spokeswoman for the Texas Department of Family and Protective Services, said the agency has had contact with the family before, but at a different location.
