On Friday, Michael A Jones, 46, of Piper, outside of Kansas City, pleaded guilty to one count of first-degree murder in the death of his son Adrian Jones after beating his seven-year-old son to death and feeding his remains to pigs.

A gruesome crime:

In November 2015, the young boy’s remains were found near a barn on the rural property in Piper, where Jones lived with his wife Heather and eight children ranging in ages from one to 11. According to the Kansas City Star, the other children lived in shocking conditions and were all home schooled.

Jennifer Hoevers, the property owner who rented the home to Michael and Heather said she was shocked and disgusted when she went inside the property for the first time since they’d been jailed. There was dead mice, cages full of rats, syringes, rat poison and pornographic videos.

Judy Conway, Adrian’s maternal grandmother, said that she felt ‘relieved’ to hear about Jones’s guilty plea.

In November, 31 year old Heather Jones, Adrian’s stepmother, pleaded guilty to first-degree murder and child abuse. She was sentenced to life imprisonment with the possibility of parole in 25 years and was also sentenced to an additional five years and eight months after pleading guilty to two counts of child abuse.

According to the Kansas City Star, Michael Jones’ sentencing will be May 3. He faces life imprisonment with the possibility of parole in 25 years.

Claims of abuse:

Jeff Coon, Heather Jones’ father, said that she called him on Thanksgiving and told him Michael had killed the little boy and it would be ‘all over the news,’ and that’s the last time they talked. Days later, Coon learned that his daughter had been telling the truth.

He said: ‘I don’t know if I didn’t want to believe her. She was just calm, just like we’re talking now. That’s why I never gave it another thought.’

Coon hadn’t seen Adrian for two years, due to his estrangement with his daughter.

Multiple people contacted the Kansas Department For Children and Families with concerns about the children and their living conditions, according to the family’s babysitter. It’s not clear if anything was done.

Heather Jones’s brother, Michael Williams, claims that Michael had abused his wife and the children in the home for years. He told NBC News ‘There are bullet holes in the walls of that house. So I’m sure you can understand what terror may have been going through that household daily.’
