The Tippit Case in the New Millenium

[Milo Reech]

Doesn't "every day" suggest Scoggins eat his lunch there often and Tippit would visit his GF after a quick lunch at home with the wife?

Exactly, familiar faces in the neighborhood.

Olsen admirably fits the minimum cab-commandeer requirements:
1. Young (29)
2. Looked like a cop
3. Unknown to Russell

The last is critical, close to impossible that Russell would not have recognized Callaway at the scene.

BTW Olsen had bushy hair. Photo taken when he was a teen, attributes otherwise unknown. I cannot locate info as to his height & weight.

As for Tippit's gun, the trail grows cold after Scoggins returns to 10th and hands it off to DPD. There's no indication as to how it came into Bardin's possession, but the topic loses much of its interest at this point.
