The body of a missing 17-year-old was discovered in a pond near Celestine in Dubois County around noon Monday.

Zachary “Zach” Ryan Patton, 17, Jasper, was last seen around 4 a.m. Sunday at a farm near Celestine. Patton was attending a party there with several other high school students from the Jasper area. His family had reported him missing and a search on foot, by boat and air was centered around the address where he was last seen, 3880E SR 164. His body was found in a pond on that property and was positively identified by the Dubois County coroner at the scene.

An autopsy was completed Monday but an exact cause of death was not determined, pending toxicology results. State police said they do not believe foul play was involved in the case and the investigation is continuing.
