The parents allegedly forced the young boy to stand in a cold shower and beat him three days before the child was reported missing to police, according to a criminal complaint filed Thursday.
The complaint alleges that on April 15, AJ's parents forced him "to remain in a cold shower for an extended period of time and/or struck [AJ] on or about his body, knowing that said acts would cause the death of [AJ], thereby causing the death."
The complaint alleges the parents beat AJ to death three days before reporting him missing, when they claimed in a 911 call on April 18 that they could not find their son after putting him to bed the night before.
Crystal Lake police said Wednesday that investigators located a body wrapped in plastic and buried in a shallow grave in a remote area of Woodstock, just miles from the Crystal Lake home where the boy was reported missing six days earlier.
Police said both parents were questioned overnight Tuesday and into Wednesday morning after information was obtained during a "forensic analysis of cell phone data."
"Once presented with the evidence obtained by investigators, both Joann and Andrew Sr. provided information that ultimately led to the recovery, what we believe is the recovery of deceased subject AJ," Crystal Lake Police Chief James Black.
Law enforcement and first responders descended on a large wooded area in Woodstock Wednesday morning. At the same time, police were seen searching the family's home on Dole Avenue in Crystal Lake.
Moments later, evidence technicians brought items from an evidence van into the Crystal Lake police station. Those items included a mattress, a large bin, two large brown bags, and an item that appeared to be a shovel with a long wooden handle.
"To AJ’s family, it is our hope that you may have some solace in knowing that AJ is no longer suffering and his killers have been brought to justice," Black said Wednesday. "We would also like to thank the community for their support and assistance during this difficult time. To AJ, we know you are at peace playing in heaven’s playground and are happy you no longer have to suffer."
