That's what I've been wondering all along is if there is other video from the highway dept. or the City or whoever owns the bridge. Or in town at gas station, or a neighbor's cam. With cam's everywhere now, he's got to be in some somewhere, and it could take quite a while to sift thru all that. In a similar but much larger park in my area, the police and park service have cams all over the woods and the lake. You can swim only in one area of the lake and if your big toe so much as dips into the water that isn't designated for swimming, you either get a ticket in the mail or a deputy shows up at your door with it. Same as if you go over the 20 mph limit. I've often looked all around the trees, etc. looking for cameras and I've never seen any at all. My hope is that this horrible thing has not only woken up this town, but similar towns and areas with such secluded parks and trails to do better security and education of the patrons. So aggravating that with all the cameras all over the place "for our safety" that so many murders are unsolved all over the place. I hope that bridge gets torn down, historic or not, and I'm a big history person, it's in need of lots of repair and I can't imagine that whoever owns it would want to pay out a lawsuit if someone is injured on it and I can't fathom any insurance company allowing it. We had a two step porch on our old house that the insurance company made us put rails on.
