If RL has lived there for 53 years, wouldn't you think the locals would recognize him and his voice by now? Even the LE, whom have had numerous run ins with him- they don't recognize Him from the image. Nobody that lives in Delphi is screaming "that's him!" Which I find odd.. I do lean towards someone being on his property and LE had some probable cause to research everything.
The reporting on this case is off.. why isn't any news stations reporting that LE has finished the search or they are still out there, etc..?
Perhaps RL doesn't interact much with others.
