A 5-year-old boy went missing in Illinois and cops said Monday that the mother of the child was not cooperating with the investigation.

Andrew “AJ” Freund was reported missing from his Crystal Lake home by his parents Thursday morning when they claimed they had not seen him since he went to bed the night before, according to police.

Cops said they do not believe Andrew was kidnapped or ran away, and the boy’s mother, JoAnn Cunningham, is not helping to find him.

“As of today’s date, JoAnn Cunningham, the boy’s mother, continues to be uncooperative with police,” the Crystal Lake Police Department said in a statement.

“Andrew Freund, the boy’s father, did speak with police detectives. Investigators are continuing to review evidence, leads, and tips as they become available.”

State officials are considering whether to place AJ’s younger sibling, Parker, in protective custody due to previous visits to the home by police.

“We’ve seen the kids been taken away and always shocked they have been returned,” neighbor Jeanne Butler told WLS-TV.

Crystal Lake police have called the family’s home a crime scene. There has not been an arrest in the boy’s disappearance.
