Wisconsin search teams found car keys and a wallet belonging to a missing Illinois teen in a pair of pants hanging from a branch in a river.

Lee Cutler, 18, of Buffalo Grove, Ill., was reported missing last weekend after attending a friend's birthday party. Police started a search of the area near Baraboo River after his 2007 Toyota Corolla parked near a rest stop.

Search divers found a pair of tan slacks Friday with the keys belonging to the Corolla and wallet with Cutler's identification on a partially submerged branch in the Baraboo River. A black leather belt was found on a nearby branch believed to belong to Cutler, according to a report issued by the Sauk County Sheriff's Office.

The items were found about 300 yards downstream from where a backpack and blankets were discovered on Monday.

Cutler's cell phone indicated the last time it was used was at 12:30 am. Saturday.
