I am not getting my hopes up, but I am not ruling him out for Delphi. A couple things IMO regarding comments that he may not be a great match to the sketch. IF he did commit the Delphi crimes, I'm sure he would know the sketch was out in the media and could purposely try to change small things about his appearance to not resemble it while not setting off alarm bells to those near to him. I know a few mentioned the shape of his nose, which is obviously a lot harder to change, but it is also a sketch. It isn't a photo, so it won't be a perfect image of him.
IF the link to Delphi mentioned in this thread is true, that is huge for me. He could have either had family business in the area OR just known about Delphi from this connection, known about the bridge, etc., and decided to travel there to fulfill whatever gross urge he had going on, especially thinking that living in MO, there would be no obvious link between him and that crime. He could have committed that crime and been back home later that evening. JMO
