JoAnn Cunningham and Andrew Freund Sr. both have criminal records. Cunningham’s dates back to battery charge in 2013. She negotiated a plea deal, paid a fine and got six months supervision, anger counseling and drug addiction treatment.

The same year, she was charged with retail theft, took another plea and received more supervision and fines.

This was all while the Department of Children and Family Services was investigating Cunningham for neglect after A.J. was born with opiates in his system.

A.J. was put into protective custody at a foster home in 2013. In 2015, records show A.J. was returned to Cunningham. In 2016, that case was closed.

In 2018, Cunningham was charged with driving on a suspended license. That case is still active.

As for the father, Andrew Freund Sr. is a lawyer but was put under disciplinary probation conditions because his license was suspended and he was held in contempt of court.

Records show financial trouble. Freund’s home, where A.J. lived, is in foreclosure. Freund is representing himself in that case.

As for his criminal history, Freund was charged with retail theft in 2013, and received one year supervision and drug and alcohol treatment. A year earlier, he had two battery charges but was found not guilty.

In a statement, DCFS acting director Marc Smith said:

“After a nearly week-long search for missing Andrew ‘A.J.’ Freund, law enforcement officials today confirmed his death.  This news is heartbreaking. Protecting vulnerable children who come to our attention is at the core of our mission at DCFS. All of us feel this loss. Our priority is the care and safety of Andrew’s younger sibling. We will continue to cooperate with law enforcement in their ongoing investigation.
