On Tuesday, the Wise County Sheriff's Office was sent to the home of Paige Harkings and Andrew Fabila, both 24, on a call about a domestic disturbance.
Wise County deputies discovered the children after receiving a report of domestic violence at a residence in Newark, about 30 miles north of Fort Worth.
The oldest two were locked in the cage that was just 3-by-3 feet, and the other two were filthy and only partially clothed, Akin said.
Akin said Harkings is the biological mother of all four children, and Fabila is the biological father of one child. They were all taken to Cook Children's Medical Center in Fort Worth.
Andrew Joseph Fabila and Paige Isabow Harkings are each charged with four counts of criminal child endangerment.
Initial reports quoted Akin as saying two children were found caged in the barn and two were found in the home. Joseph Fabila and Harkings, the mother of the four children, have been jailed without bond after the children were found at their rural home.
Their parents, David and Louise Turpin, were arrested shortly after and charged with almost 50 counts of child abuse, torture and false imprisonment.
The children were found by cops who described the discovery as the worst case of child abuse they had ever seen. However, they were inside of locked cabinets with no way for the children to unlock them. She declined to share details of their condition and treatment. The agency did not say if the children have been placed together or split up.
Akin said the suspects, who have not been identified, are facing four counts each of endangering a child.
The Wise County Sheriff's Department told reporters that responding deputies found a man with cuts to his face and spoke to the couple about the incident. Officials think they were living at the home for several weeks, KMOV reported. Deputies fed the kids and gave them water before taking them to the hospital, according to the sheriff's office.
The couple has had contact with the Department of Children Services before Tuesday's investigation, according to DFPS spokeswoman Marissa Gonzales.
