I thought the shooter stopped at McDonalds?
He did. After he stopped at the Walmart Subway.
The info I have read said that he walked to WALMART and stopped at the SUBWAY (one must assume it was in the WALMART), then he walked to McDonald's.
A question no one has asked yet, that I can find, is WHY ?
Of course, Cruz is allegedly autistic, so It would be hard to judge what he was doing going by NORMAL standards of behavior.
