I'm sure things will make sense when more details come out. Here's a quote from the Dispatch: He (the tow truck driver) told police that his emergency lights were on, and that he honked his horn when he saw the Explorer approaching in his rear view mirror. I don't know what's more strange, not seeing the tow truck or the driver of the tow truck seeing him coming and honking. Makes me curious if it was parked around a turn or something. Sad stuff.
