Thinking out loud - Wouldn't a killer, if had been off roading with her van, to dump the body, have taken the van to get it cleaned off (perhaps, but if people are looking for it, very risky in town at a car wash I agree). If the lookout for the van was active, the Van IMO wouldn't have been driven far where it could have easily been spotted.
If coming back into town from the direction where the cell phone was tossed, I'd look at Blackman Road (that's a seasonal road and a van could get through that road but would get covered in mud to make it, especially in December), or John Smith Road (another seasonal one that leads up to Jackson Pond (one I've suspected all along as a VERY remote area and not Public), else all of the roads between SR23 and County Route 16 would be VERY muddy out there as they are all seasonal. South of State Route 23 out in that general area is the North Road, that leads up to (heading back towards Norwich) the CCC Truck Trail through the New Michigan State Forest (has the Finger Lakes Trail running through it), and that Truck Trail leads back to Blackman Road (and close to Round Pond - another area on Private Land) bordering the State Land.
Between her house and where the van was dumped, there aren't as many (Muddy off roading roads) as there are over here west of State Route 12. To get muddy over east of State Route 12, you'd have to go east from where she lived and then back west to where the van / phone was found.
Thanks RB - appreciate the info.Do you have details as to what GR says he was doing. I already have from Lavonda that he was supposed signed into his work server all moring working from home. But when did he leave to go running? When did he get home? When did the kids find out?
RB - do you think that more searches should be conducted? Thanks again!!
