AJ Freund

The Illinois couple accused ofkilling their 5-year-old son before making public appeals for his safe returnallegedly beat the boy to death after he lied about soiling his underwear, according to newly-released court documents.

Investigators allege in a search warrant filed with the court on April 29 that Andrew Freund Sr., 60, admitted to police that he and JoAnn Cunningham, 36, forced their son Andrew “A.J.” Freund to take a cold, 20-minute shower on April 14 before sending him off to bed “cold, wet and naked.”

The punishment was for A.J.’s lying about soiling his underwear, the warrant states.

The couple, the warrant alleges, allegedly decided instead to subject their son to cold, prolonged showers.

A.J.’s parents have both been arrested on murder and other charges.

Both are being held on $5 million bond.

The new filing alleges both parents confessed to police after being confronted with a “forensic analysis of cell phone data,” which showed their phones pinged near where the boy’s body was discovered.
