Ok, not to mess up any time lines, but...
Chelan County Sheriff's Office spokesman Jerry Moore, when asked when MC went missing, stated: "Tuesday, February 9th at 3:15 was the last time we
heard from MacKenzie"
This is from a
verbal interview at golakechelan on the day MC's body was found, Feb. 13th.
The word "heard" seems to be emphasized by the spokesman, which makes sense because the
WW article from earlier that day said LE was gonna "pore over more than 1,000 pages of phone records." According to our cell phone experts, IIRC, these initial records would have been the billing records showing numbers and texts sent or received and the time they were placed or received.
Therefore, with the information fresh in the spokesman's mind, I think we have been told the time of MC's last voice phone call, 3:15 on Feb. 9th, (although not whether MC placed or received it).
A 3:15 phone call doesn't match up with anything on our time-line... yet. But -- SPECULATION -- it would be about the right time for her to place a call -- leaving school at 3:01 and driving for ten or so minutes, then placing a call to someone. More speculation: maybe the phone call was her saying, "I'm outta school and waiting for you. How long till you get here?" --OR-- "I'm outta school. Where do you wanna meet?" This might account for what MC was doing until the last reported text message of "hey" at 3:40 from boat launch. It was 20 or so minutes partially spent driving to and then waiting at the boat launch area for the person she had called at 3:15. <--SPECULATION of course.
Still, maybe she received this 3:15 call from someone else, although I don't think likely. Person calling would not have wanted to bug her while she was still at school and it sounds like, according to her bf, (via Melissa), MC's schedule wasn't firm for that day -- not even sure she was gonna go to school at all -- so how would this other person know in advance that she would be done by 3:15? Just sounds more like a case of, "I'll call you when I'm free" kind of situation, IMO.
More pondering... sigh...
