Jake Cefolia, an executive with United Airlines, disappeared on August 6, 2020. Police found Cefolia’s 2019 Range Rover abandoned at the Waterfall Glen Nature Preserve, near Lemont, Illinois. Many believe that Cefolia walked into the 700-acre forest and never walked back out, perhaps taking his own life. However, Jake Cefolia had secrets and has often fantasized about living off the grid.
