LaPorte County police said the camera, which was attached to two large, white helium balloons, was found Monday by Rolling Prairie farmer Robert Tibbs, 66, the Northwest Indiana Times reported Friday.
Detective Pat Cicero said the camera, which is about the size of a pack of cigarettes, contained images of Lake Michigan, Soldier Field and Michigan City. He said the camera also had pictures of the two unidentified people who launched it from outside of a Chicago school.
"We're trying to establish who these people are that did this," Cicero told WBEZ-FM, Chicago. "We just want to return their stuff to them."
