UPDATE 8:30 a.m. Waukesha Police are asking volunteers to please wear boots or tennis shoes if they want to participate in the search for Andrew. They say flip flops should not be worn.
More than 300 volunteers have shown up so far Monday to search for Andrew. Officers say his scooter was found overnight.
At a news conference, police asked people in the area to check under their cars before driving, as Andrew may be hiding underneath a vehicle. He is non-verbal, so if you see him you should call police.
UPDATE 1:00 a.m. Waukesha Police said they are still actively searching using civilian K-9 units. They are mobilizing trained searchers to form small groups and re-canvas areas. A National Guard Black Hawk helicopter is on its way from West Bend to search from above.
UPDATE 12:37 a.m. Police are asking all volunteers to go home and return in the morning if they would like to continue searching. Heavy fog in the area is making it too dangerous for volunteers to walk around the neighborhood. Volunteers are asked to return to Waukesha West High School at 6 a.m.
Original story below:
Authorities from multiple agencies are searching for a missing 10-year-old boy with autism.
Andrew Ounkham was last seen around 3:45 p.m. Sunday afternoon, running through a large cornfield behind his home, located near Stillwater Circle and Oxbow Drive. He was last seen wearing a blue shirt and grey shorts.
Police say Andrew has been diagnosed with Autism Spectrum Disorder and is non-verbal.
Waukesha Police have set up a command post at a nearby park. They are working with multiple local and state agencies in the search.
A ladder truck with Waukesha fire set up near the entrance to the corn field, lighting up the ladder in bright colors to try and get Andrew's attention.
Authorities are also using K9 units, drones and thermal imaging to search the area. They are also working with the National Guard to bring in a Black Hawk helicopter.
Andrew's parents told police he has done this before and will often run into the corn field when he's upset. They can usually find him right away.
Police also said Andrew likes to hide in backyard play sets when he's upset. They do not believe there is anything suspicious surrounding his disappearance.
Anyone who has seen Andrew or has information of his location are asked to call the Waukesha Police Department Communications Center at: (262) 524-3827
