I agree, I think he's more impulsive and takes his victim right to the site he rapes and murders them at. Although I do believe he is a serial rapist and murderer, I don't think he is as calculating as some give him credit for. I think it's more a matter of impulse, urges, and opportunity, along with timing (the fall season). I think the more he got away with, the cockier he got, and sloppier he got. I can see him taking trophies. But I can't really imagine he was that calculated other than having learned of some really remote locations to dump a body, which were likely known to him just by growing up in Charlottesville and driving a taxi. I don't see him raping at one site, moving the body to another, then going back to visit and/or possibly move the body again, or leave clues to taunt the police, etc. I think he did his despicable crimes and then tried to distance himself and try to rationalize what he did and pretend it didn't happen. JMO.
