Andrew "AJ" Freund's parents said they last saw him Wednesday evening. Thursday police went in and out of 5-year-old Andrew's home in Crystal Lake and the FBI joined the search.
AJ was last seen at around 9 p.m. Wednesday night when his parents told police he went to bed, but by Thursday morning, he was missing, police said.
Law enforcement from several agencies searched the neighborhood with trained dogs and FBI agents were seen leaving with what appeared to be items from the home. Teams on Crystal Lake used sonar equipment in an effort to locate the boy.
The neighborhood is worried and shaken.
"We don't know if he wandered out. That was the first thought - did he wander out? But nobody's seen him, so nobody has any clue whatsoever," said neighbor Janelle Butler.
Police said they didn't issue an Amber Alert because they could not confirm that a kidnapping had occurred. However, investigators are calling AJ's home a crime scene.
It's believed AJ's parents are still with police.
AJ has short, blond hair and is approximately 3'5", weighing 70 pounds. He was last seen wearing a blue Mario sweatshirt and black sweatpants.
