A Kansas man is being held on $10 million bond after police were made aware of his missing 7-year-old son and found unidentified human remains on his property.

Michael A. Jones made his first court appearance Monday. The 44-year-old Kansa City bail bondsman is charged with child abuse, aggravated battery and aggravated assault with a firearm.

Prosecutors say he doesn't appear to have an attorney.

Police were called to Jones' home Wednesday to respond to an unspecified disturbance. While there, investigators were told Jones' son had been missing "for an extended period of time."

Police didn't say who told officers about the boy, but say human remains were later found in Jones' barn. Prosecutors say Jones is accused of assaulting a woman and "torturing or cruelly beating" his 7-year-old son.
