CRYSTAL LAKE, Ill. (KTVI) -- The Illinois woman charged with murder in the death of her 5-year-old son, AJ Freund, is pregnant and will likely give birth while in detention.

The body of AJ Freund was found in a shallow grave last month in Woodstock, Illinois, about 10 miles from his home in Crystal Lake. His parents, JoAnn Cunningham and Andrew Freund Sr., were arrested and charged with murder, aggravated battery and failure to report a missing child or death.

Cunningham is seven months’ pregnant, WGN reported.

Once her baby is born, the Illinois Department of Children and Family Services will receive a call from the hospital to initiate its involvement with the child, said Jassen Strokosch, the agency’s spokesman.

“… Plans for the newborn will need to include permanency in another home,” Strokosch said. “This could be with relatives or another foster care home. Ultimately, the decision will be up to a judge, but most likely the goal will be to work toward adoption.”

Consideration will be given to family members

In Illinois, consideration for children born to mothers serving time is given to family members if it’s in the best interest of the child. Court documents obtained by CNN on Thursday said the father of Cunningham’s baby is not Freund.

“If the father is able to care for the newborn, they would have custody of the child,” Strokosch said. “If there isn’t a father available and absent other plans, DCFS becomes involved. We would work with the courts to create a plan for the child based on the best interest of the newborn.”

A judge will look at several factors to determine custody. The parents have agreed to let the state’s child welfare agency care for a younger son, WGN reported. County prosecutors filed a petition to terminate Cunningham and Freund’s parental rights to the younger boy, the TV station said, citing local reports.
