Michael Jones, 44, was held after reports that he had assaulted his wife at their home and fired a gun at her.
But when police began investigating, they were tipped off that they should search the family’s backyard for the decomposing remains of their missing son.
The next day, human remains were found at a barn on their property in Wyandotte County.
Local women who knew the family said the couple had eight children, but their son had disappeared earlier this year. They also claimed Jones’ wife added livestock to the barn in September.
“Their house was horrible,” one anonymous woman told WSFA.com. “Their house was just filthy. The kids lived in filth. Trash everywhere. Dried food all over the house.”
The seven other children are believed to be safe and in protective custody.
A police source said investigators fear the remains are the result of the child being fed to pigs after being beaten to death. The remains have yet to be identified.
Jones is expected to have a first appearance in Wyandotte County District Court on Monday.
