The family's car was found late Monday morning at O'Hare Airport. Moosemiller was found with a CTA agent and taken to police headquarters.
"Obviously relieved. It's been a scary morning. So, you know, we've been driving around just trying to find him and stuff. And (his) dad's out of the country, and he knew his son was missing and felt very helpless... and just glad that he's OK," said Vicki McLennan, family friend.
It is not clear what led Moosemiller to O'Hare.
