Police are investigating an incident of indecent exposure at the Elkhart County 4-H Fairgrounds. It happened on Satuday, the final night of the 4H Fair. Investigators say a 15 year-old boy told them a man exposed himself to the teen inside a restroom. The Elhart Truth reports officers located and identified the 59 year-old suspect, but could not arrest him because the officers did not witness the incident. A spokesman for the Sheriff's Department says with this kind of incident there are certain elements of the crime that must be met in order to make an arrest.
