MC was not expected to a “special” dinner at RC that night. She was living with him and every night dinner was at a certain time. So the expected for dinner just means she was expected home at dinner time, as usual. MC obviously met someone, somewhere. We don’t think the car wash is pertinent as from what we can surmise it was an eye witness account several days after and eye witnesses are not reliable (he could have had date wrong, mis- identification, etc.) Lowe’s, brothers are not involved either.
The spec home was searched right after the body was found, maybe MC had a key on her that had that address on it and that is why they searched it. Maybe she was using the house as a rendezvous place. She knew the place as she had helped WC in past with yard and clean up work there, she may have had her own key to it.
This might have been where she and killer met, there was an argument and MC was killed. The killer called for help, to move MC vehicle (neighbors at that time did not suspect because they were use to seeing MC vehicle at the spec home.) what ever did happen at spec home (if anything) was not bloody as realtors held an impromptu open house the Sunday after they body was found. We were thinking that a realtor showing the home called LE but since the home was not searched until shortly after the body was found we have dismissed that idea.
MC body was moved to CB during daylight hours. The property is listed and neighbors would not think about a vehicle being there and people looking around. It had to be daylight for the killer(s) to see trail, maybe use a wheelbarrow that was on site (in photos there is other equipment visible) and haul body down trial. They weren’t expecting blind it was an unexpected bonus. The feet were in the water because the body was put head towards handles and when the barrow was dumped, the feet went out first and into water.
The killer probably figures they were buying time and were surprise that someone stumbled across it so fast. We do not think there were any plans to use a boat.
Uh! Forgot to specifically state that the message above is pure speculation on all of our parts and we don't even agree on some of it.
