It appears that the body was found in some sort of run off ditch, is this correct? Is it possible (for those familiar with the area) that the body was deposited somewhere else and washed down to that location? IIRC there have been rains in recent days, correct?
Not likely with the type of ditch that it is, and the types of rain that we had here. We had rain, but no floods, mostly wind. The area where the body was found is all semi-industrial buildings, the type of place that would be completely empty at all but business hours. Because Christmas was on a weekend, it's possible (though I have heard no mention of it yet) that the body was there on the weekend, no one worked on Monday for Christmas break, and they only found the body today because people were going back to work. Many of the businesses like these around here take a weekday off on Monday if a holiday falls on a weekend. Likely the person who dumped the body thought that the cameras wouldn't "see" that far. Let's hope they were wrong!!
Someone was mentioning something about finding woods, but if you had a recently burned body in your car, I'd suspect that no matter what you "planned" you'd change your mind when you realize that the smell that had to be coming from the body was going to stay in your car.
In that area, I suspect he or she would have to drive a good bit to find any woods where you could be as unnoticed going into them as you would be in that sort of semi-industrial area.
When I saw the area where the unidentified body was found, I was not surprised. I live in a similar area and after 7 at night, it's like being in the middle of the country - there's no one out here. People dump LESS horrible things here all the time for that very reason. That area looks even less populated. All in all it's just horrible. A ditch, for heaven's sakes - as if it weren't bad enough to kill, burn, and discard someone??
