Weigman film captures Lovelady on the steps 1st. Weigman film also captures Mr.Campbell with presumably Mrs Reid, standing on the curb of Elm st, as Wiegmans car goes past. Mrs Reid may be the heavyset older woman in white scarf right beside Mr.Campbell.
Then Altgens 6 photo captures Lovelady still on the steps approx at Z255 just after 2nd shot fired (although imo, z233may be the FIRST shot heard)
Then Couch film supposedly does not start until 24 seconds after last shot fired and is capturing Lovelady and Shelly moving away and Gloria Cavalry at the front steps talking to Joe Molina, and there is finally BW Frazier seen, who moved up to the top hand railing after Shelly had left to join with Billy lovelady,
Thats how i understand the sequence. Its this not correct?
