She said it John..... Perhaps not verbatim.... But Mrs Roberts said that Lee arrived at the rooming house at 1:00pm ...and he was in his room for several minutes and then left...the last time she saw him he was STANDING ( not running toward 10th and Patton) at the bus stop in front of the rooming house.
You lot have a tendency to shave/add to time, height and weight estimates.
Dirty Little Harvey didn't have to run according to precise testing. Could have made it in 11 (+-) minutes by walking briskly according to the vid I just posted here. Just in time to bump into his destiny.
And could have been faster than that if he had had his hands out of his pockets, IMO. I walk all the time and having your hands swinging freely helps create & keep an easy momentum and encourages longer strides as well.
And by the way, I've personally found that
trotting is the easiest way to maintain a speed somewhat faster than brisk walking. Oswald was seen as 'trotting' away from the scene by Markham, which suggests he might have trotted along at times while on his walking/trotting/jogging/running tour around the 'hood.
Bottom line Oswald was positively ID'd on scene.
