I am all caught up. I am wondering if anyone else thinks MC was kept prisoner for a time. It seems so rushed in the time line to get from Wenatchee to Crescent Bar, and back to ditch the car at Pitcher Canyon by 7:00 p.m. If this was an act of rage or revenge, it just makes sense to me that at some point, around 4:00 p.m. with the alleged car wash siting, MC's passenger changed from a friend/acquaintance in the passenger seat, to an abductor. Here is one possible scenario. After the car wash, the passenger pulls a weapon on MC, and insists she drive to a location. (Possibly the spec. house where rumored disturbing evidence is seen) Here she would be bound and held prisoner. The perp would obviously take her phone and turn it off, at this point. (Possibly 5:42 by this time, and it is destroyed)
I would guess one person would stay with MC, while a second drove the car, and disposed of it. They either walked out, OR had another accomplice to pick them up. With all the mud on MC's tires, it DOES look very much like her car was possibly taken to a construction site. I mentioned this several threads back. When we built, even if the streets were dry, in winter with snow melting on uneven soil in a construction site driveway, my tires were coated in the exact same way. The clay soil sticks horribly, and is very predominant in the Eaglerock area. I also frequently wash my car, and while the front is totally clean, the minute I drive on the roads with de-icer, and sludge, the rear looks like it hasn't been washed for a week. I do agree with whoever posted the water trails coming down the spoiler of MC's car...totally the result of clear water being sprayed over the car from above.
Once the car is ditched, the perps. then have time to confront MC, and let her know how she wronged them. Now it is dark, easier to transport someone against their will. She could have received the major blow to the head at this point, and is transported unconscious to CB. ( maybe even in the trunk of a car) Blunt force trauma as the cause of death does not indicate she died instantly from this injury, although it is listed as the primary cause of death. IMO, the brain damage would be similar to a head trauma accident, where the brain injury causes swelling, and ultimately causes death once the swelling constricts blood flow and causes the brain to die. This could take a few hours to a few days. MC could have even regained consciousness and had further interaction with the perps. (Thinking of Natasha Richardson, who hit her head while skiing, functioned normally, and then passed away the next day due to the blunt force trauma of the tree she hit)
Once she is transported to CB, in the dark of night she is dragged out to the field, and confronted further. Let's say she did regain consciousness, that would allow for the secondary causes of death, the strangulation, and stabbing in the neck. The head injury would be the ultimate cause of death, as it was inflicted first, and then death was hastened by the strangulation and stabbing?
Anyway, just speculation....trying to figure it out. We all want you to Rest in Peace, dear Mackenzie. I am certain the killer(s) must be caught and justice served so she can receive peace fully.
