Just some thoughts about the blood evidence found in/under the truck (and apologies in advance for how awful this all is)...
If DM was in the driver's seat when he shot Tim and it blew out the passenger side window, there is NO way they were going to drive all the way back to the hangar in Waterloo with Tim in the front passenger seat. The most likely scenario is, they (DM and MS) got out, put Tim in the back, laying down on the seat so as not to be seen, and headed to Waterloo. That would explain the evidence of gunshot residue in the FRONT of the truck, but there also being blood evidence in the back of the truck. As for Tim's blood being on the undercarriage of the truck, I can only imagine it was very messy by the time they got to the hangar and the blood had likely already begun to seep between the door and the frame - making it's way to the underside as well.
I know they haven't been convicted yet, so it's all "alleged" this and "alleged" that, even the news/talk radio dude today on am980 was all "we don't really know who did this" and I'm screaming in my van "are you seriously THAT dumb?!" :gaah: Ugh. There is no question in my mind, none whatsoever the correct parties are being tried for this crime.
Of course, this is entirely moo, based on what would seem to be so much more evidence than most cases ever have. There. Just had to vent a little.
