A Texas woman has been arrested after San Antonio, Texas deputies received a call about hearing a child crying for “a long period of time” and seemed to be coming from a nearby back yard.

At just before, Bexar County deputies arrived at the house. When no one answered knocks at the home’s front door, they went looking around. It was then that they came across two children bound in chains.

“One of the toddlers was chained to the ground; the other was tied to a door with a dog leash,” the sheriff’s office said in a release.

“It’s sickening. To call this horrific would be an understatement,” spokesman James Keith told a local newspaper. “If it wasn’t for our deputies and this caller who tipped us off, we know that this could have had an even worse outcome.”

Once they saw that, they gained entry into the home. There, they found six more children, ages 10 months to 13 years. Not a single adult was to be found.

The parents returned home later in the early hours of this past Friday morning.

34-year-old Porucha Phillips was arrested and has been charged with two felony counts of injury to a child.

“It’s believed she was responsible for the care of the two children who were found tied up outside,” the sheriff’s office said in a release.

The 3-year-old girl who’d been tied up with a dog leash was found to have a broken arm.

The other child, a 2-year-old boy, had been chained to the ground by his ankle, “the same kind of setup you would use for a dog,” Keith told the Associated Press

Both children were taken to a local children’s hospital to be treated. All eight of the children are now in the care of Child Protective Services.
