“I would give my life to have A.J. back,” Cunningham said in court. “This is something I will never escape from. I am impacted forever.”

But when A.J. went missing in April 2019, Cunningham told Crystal Lake detectives she had nothing to do with his disappearance. That turned out to be a lie.

A.J.’s father, Andrew Freund, ultimately led police to the boy’s shallow grave. That was just some of the evidence and testimony presented at Cunningham’s sentencing hearing on Thursday.

She switched her murder plea from not guilty to guilty in December.

Prosecutors also played video and audio from Cunningham’s cell phone. One recording was her berating AJ about going to the bathroom a month before she killed him.
