Ht2, that would mean every one of his co-workers were outside the building watching the motorcade (how else could they be confident lho wasn't), which means he evaded them all as he escaped, assuming they subsequently all ran back into the building from which they must have just heard 3/4 shots ring out, then stayed around for a headcount- assuming they must have returned very quickly for lho to be identified as "missing". Again, what would you do? Seems fairly crazy that if you ran away down the street in fear of your life and were reluctant to return for a.while to the area you just heard gunfire from that the cops would then put out an immediate apb on you as chief suspect?
