Heres the rough draft of my theories:
At 3:00 p.m., MC leaves the Hair Academy, turns onto Kittitas, then turns right onto northbound Mission Street, and drives to WCs office (about 1 minute). MCs purpose is to tell WC about her new medical condition.
MC meets WC at WCs office on Mission Street, and they walk or drive together to the boat launch to talk. Either which way, MCs car is left at WCs office.
Sometime before 5:00 p.m., MC and WC travel to WCs house in Eagle Rock.
Sometime between 5:00 p.m. and 6:00 p.m., WC freaks out on MC and, in a fit of passion, slays MC (probably with a kitchen knife?). (FYI: The reason I believe WC is the murderer, as opposed to JF, is simply because no mother would continue to have a relationship withlet alone purchase a new car forany person who may have possibly murdered her child; I refuse to believe thats physiologically possible.)
After the deed is done, WC contacts JF and extorts him into helping her dispose of MCs body. If JF is the cause of MCs medical condition, then WCs extortion would be fairly easy and obvious.
WC must move MCs car because it would be way too obvious who the perp is if it remains where it was at that time. Therefore, WC drives MCs car up to Pitcher Canyon and JF follows. At about 7:00 p.m., they drop off MCs car at the end of Pitcher Canyon Road, and JF drives WC back to her house/office.
WC and/or JF and/or his brother(s) then transport MCs body to the Sunnyslope spec house for temporary storage. Said house is, after all, close by WCs home (less than a 6 minute drive). Although I believe its possible (though not probable) that they tried to dismember her body parts, I dont believe they would have done so at the Sunnyslope house. And I certainly dont believe they attempted to mutilate MCs body for sheer entertainment. In any event, something horrible is done to MCs body.
Sometime between 11:00 p.m. on February 9 and 6:00 a.m. on February 13, WC and/or JF and/or his brother(s) transport MCs body to CB. They decide on that particular location because they are familiar with it, and they know it buttresses the county line.
They place MCs body near the stream, with her feet in it. They were intending to place MCs body just inside Grant County in order to create a jurisdictional headache and friction between 4 LE agencies. But they failed to do so (for whatever reason, e.g., simple miscalculation, too dark, too wet, or maybe they were unable to cross the stream and they did not want to carry her body back up the hill; they therefore placed her body as close to the Grant County as possible). I believe her body was placed in the brush and trees along the stream, approximately 15-feet from the river.
That's all I got so far. So, go ahead and rip up my theories.
DISCLAIMER: Everything except for the first three words is pure speculation. I certainly could not prove any of this beyond a reasonable doubt.
