Could you check on that controlled deer hunt? I know it is a remote possibility, but the area is only 34 minutes from that bar where Star went missing and less from where Renee went missing. If it put Shon in a location where he is familiar and not afraid of being seen or noticed due to it being so isolated...I think this would be better than dumping her into a river where she could be found much easier by washing up.
Both women could be in or around the same location.
Were you around that area 10 years ago? I just wonder if the activity at the lake has decreased since then? A man like Shon, imo, would be one of those to gravitate towards hunting, boating, and fishing. (I could be wrong about that, but is a guess.)
