Andrew "AJ" Freund was last seen by his parents on Wednesday—when they put him to bed, they told police.
In the days since, police have focused their search on the family’s Crystal Lake home, saying they do not believe the child was abducted.
They’ve also searched nearby Crystal Lake and on Monday— Lippold Park.
Janelle Butler is the family's neighbor.
"At this point we just want it to be over," she said.
The missing boy's father continues to stay at the family’s home.
Police say Andrew’s father met with investigators over the weekend and that the dialogue is ongoing.
"I have no control over what people think," Andrew Freund Sr. said. "I just want my son to come home, OK."
Police say Andrew's mother, Joann Cunningham—who spoke to Good Morning America over the weekend—is not cooperating.
"I just want him to come home," she said on Good Morning America.
George Kililis, Cunningham's attorney, said police stopped searching for the missing boy, but police say that's not true.
“When it became clear law enforcement was not conducting a missing child investigation, was not issuing an Amber Alert, had stopped searching for AJ, and considered her a suspect, we did advise her to stop all communications with law enforcement and she did so at our request," he said.
Crystal Lake police tell NBC 5 that there are no suspects in the case.
They also say that police never stopped searching for Andrew and continue to work as hard as they can.
