Your star witness, Helen Markham, said that the shooter had "bushy hair" and LHO did not have bushy hair.
I believe that Domingo Benavides was a far more lucid and rational witness than Markham.... And Benavides descrided the killer's hira cut as in a manner that indicated that he had taken note of the man's hair....Whereas Markham simply said that the man's hair was kinda bushy, or wind blown....
