Helen Markham swore that Tippit was shot at 1:06......
Most of the evidence points to Tippit being shot between 1:06 and 1:10.
The only thing that does not compute with those times is the (easily manipulated) DPD radio recording (made on a voice activated machine and thus unreliable for actual times) and the various transcripts of those recordings. And then of course there is the questionable claim that a very elusive time stamp card is supposed to show that the ambulance from a funeral home on Jefferson was called at 1:18. However, that notorious time stamp card is not part of the evidence and in over 50 years has never been produced.
I've been to the rooming house and walked the distance to 10th/Patton on all possible routes and there is no way that Oswald could have gotten there before 1:10.
