I think I just had a flashback to my SAT exams:great:
LOL - sounds like one of those mind-bending math application problems when we had to determine the arrival times of trains & such! Ugh! I used to be good @ those, but, alas - I fear the math lobe of my brain has gone on permanent vacation. The only math I can muster these days is this: :countsheep:
Big Kudos to anyone who wants to tackle drive times, velocity, etc.
IIRC, Velocity = Distance/Time, but I don't think that will help to figure out why SA's cell phone pinged in C-City for a full 21 minutes on December 27 if he was only passing by C-City (after allegedly stopping by his g-ma's house) to access I-20, as BD now claims - unless he was driving REALLY REALLY REALLY slowly.
IMO - he didn't go to his g-ma's house that morning, but returned to 1804 Chestnut Street.
IMO - the BD/SA timeline has been adjusted to make it fit the cell phone pings.
Until the cell phone pings were publicized, BD was telling a completely different story regarding SA's movements on the morning of December 27.
GRACE: Question, if he were back at the home, is that the cell tower his phone would ping off?
WEED: Yes, police say in the affidavit that that`s the exact same tower.
GRACE: OK. Did you know that, Billie Dunn? He didn`t go straight to his mother`s. He went back to where the home is.
DUNN: I found that out last night watching the news. He told me the same thing that he went straight to his mom`s house in Big Spring.
GRACE: Now in his defense, to get from work to his mother`s, would he drive through Colorado City?
DUNN: No, I don`t think so. He could but it would be shorter to not come through Colorado City.
Thankfully, LE only included enough information in the affidavit to secure the search warrant, otherwise, who knows what else would have changed in the current version of the BD/SA timeline from what had been stated previously.
