Police have released the 911 call that Andrew Freund Sr. made at 9:04 a.m. on Thursday to report his son, Andrew "AJ" Freund, missing.
Freund Sr. said in the call that he had discovered 5-year-old AJ missing that morning after returning home from a doctor's appointment sometime between 8:15 to 8:30 a.m.
"When I got back from the doctor's appointment, and I checked in on him to say 'good morning,'" Freund Sr. said. "And he wasn't there."
Freund Sr. told the dispatcher he had searched the home and garage "completely" and checked the local park, school and gas station down the road where the family sometimes took AJ to "buy treats."
The call, which police redacted, lasted about five minutes before a police officer arrived at the home in the first block of Dole Avenue.
No one responded to a knock on the door Tuesday morning as the search continued throughout Crystal Lake.
Sonar teams and planes will assist in the search for AJ, Crystal Lake police said in a news release sent Tuesday.
The McHenry County Emergency Management Agency and the Crystal Lake Park District police are assisting Crystal Lake police.
Search crews ended a search early Monday at Lippold Park due to inclement weather, but the search was going to continue Tuesday at the park, 1251 Route 176, police said. Crews were also at Veteran Acres Park, 431 N. Walkup Ave., on Tuesday.
As of 12:30 p.m., Crystal Lake Deputy Police Chief Thomas Kotlowski said no body had been found at Veteran Acres Park or the lake at the park.
Illinois State Police will be assisting with the search Tuesday by piloting a plane over the area to help guide those searching on the ground, according to the release. Sonar teams from a mutual aid system will be scanning several area ponds.
Police said Tuesday there was no new information to share on the case. Andrew was reported missing on Thursday by his parents, JoAnn Cunningham and Freund Sr. Police have said Andrew was not abducted.
Cunningham and her attorneys will hold a news conference on Tuesday outside the McHenry County Courthouse following a 3 p.m. hearing on whether her younger son, Parker, will be placed in protective custody by the Illinois Department of Children and Family Services.
