there is no drop off area south of the bridge. Only on the North side. In fact there are 3 areas of drop off for the bridge. In town at Riley Park, at the area just North of Hoosier Highway (the bridge is a walkway over the interstate) and there at the Monon bridge entrance. There isn't a drop off at the South. That's actually private property. Makes me think he entered through the back of the cemetery, came in the through the private path down to the Southside of the bridge, they were on the North end. I bet they saw him appear out of nowhere and thought to themselves "where the h@ll did that guy come from since they hadn't passed him on the bridge previously?
Thanks #1nana for the time you took to make the trip and to analyze this scenario. I think you are pretty spot on! IMO
