KANSAS CITY, Kan. (AP) — A coroner says human remains found at a Kansas barn are those of a juvenile, but tests to determine whether they belong to a missing 7-year-old boy will take weeks.

Police found the remains after investigating a domestic disturbance at the home of the boy’s father.  Michael A. Jones has been charged with child abuse, aggravated battery and aggravated assault with a firearm.

Wyandotte County Coroner Alan Hancock said Tuesday the remains are of a juvenile and they’ve been sent to a forensic anthropologist who will determine the child’s age. Hancock will do additional DNA testing aimed at identifying the child.

It’s unclear if Jones has a lawyer. His father, Jerome Jones of Baltimore, says his son would never hurt a child.
