(CNN) A coroner in Kansas said Tuesday that a child’s bones were found among the pigs on the property of a Kansas City man suspected of killing his 7-year-old son.
Wyandotte County Coroner Dr. Alan Hancock said his office has not determined whether the bones are those of the son of Michael A. Jones.
Jones, 44, is accused of abuse of a child, aggravated assault and aggravated battery. The case generated national headlines after claims by anonymous sources that Jones beat his son to death and fed his body to pigs.
Police have refused to address those claims.
Hancock told CNN that the unidentified child’s bones had been in the pig enclosure in a barn for several weeks.
Police were initially called to the home last Wednesday for a domestic violence situation involving the suspect’s wife, 29-year-old Heather Jones, Wyandotte County District Attorney Jerome A. Gorman said Monday.
While they were on the scene, police were told that the couple’s son had not been seen for some time, the district attorney said. The next day, authorities announced they had discovered human remains on the property.
Police are referring to the missing boy as “AJ.”
Authorities have taken six other children living in the home into police protective custody. The children are all girls younger than 11.
Child welfare services in Kansas and other states had contacts with the family, Gorman told reporters. But he wouldn’t reveal the nature of the contacts or confirm whether there were any open investigations involving the children.
Gorman said the aggravated assault and aggravated battery charges resulted from the investigation into the incident between Jones and his wife. He said the abuse of a child charge is “the tip of the iceberg,” adding that detective work needs to be done.
“Be patient,” Gorman told reporters. “The police have been working on this. A lot of them gave up their Thanksgiving Day with their families. And there’s still a lot of work for them to do that we’ve outlined. Once all of that evidence comes in, we’ll review all that and see if it warrants more charges.”
The investigation is being conducted jointly by the prosecutor’s office, the local Sheriff’s Department and the Kansas Department for Children and Families, Gorman said.
Gorman said the case has been a difficult one, both for him and for the investigators.
“From my discussions with the officers who’ve been out there, they’ve described this as one of the worst things that they have ever seen,” he told reporters.
“And for officers who have been on the street and have been detectives, for them to come up and say that this case has made them angry … you can surmise from that what kind of scene it must have been.”
Jones’ bail was set at $10 million. The judge refused to consider a bond reduction, CNN affiliate KCTV reported.
“It’s the largest bond I’ve seen in my 34 years as a prosecutor,” Gorman said.
Jones himself owns a bonding company, but he is not licensed in Wyandotte County, where he’s being held.
