So, I guess I'm back to my original theory. I see no other options. I'm always willing to go where the evidence leads, but it is going nowhere.
For a variety of reasons, I don't like any of the theories being offered. It is highly, *highly* unlikely that Toni went to an industrial area in North Kansas City for a drug transaction. NKC is crawling with cops, and you would stick out like a sore thumb. Terrible location. I also find it highly unlikely that Toni turned west when she meant to turn east. I can only see one reason for Tony to end up on that road...
Back to my theory that nobody likes: Toni is suffering some kind of psychotic break.
She is looking for a familiar body shop near the QuikTrip on 31st, but goes to the wrong QuikTrip. She turns left onto W 26, says "this ain't right," cranks a u-turn and thinks she has to go further on Burlington. While she's waiting for the light, an officer conducts a traffic stop and directs her to the QuikTrip for gas. So she gets gas. While doing so she realizes it is the wrong QuikTrip. She consults her phone once again and once again selects the wrong QuikTrip. This time she's going to the QuikTrip just north of Parkville. Or maybe even the nearby "QuikTrip Park." She gets more and more confused and ends up just driving aimlessly...
This scenario could possibly end in a tragic traffic accident, just as police believe. Or other ways.
Anyway, I think I'm going to take a break from this case. Spending too much time on it...

I'm out...
