Michael Rodelli (The Hunt for Zodiac)
"[I]t is very difficult, or even impossible for, say, a 230 pound man like Arthur Allen, who was the primary suspect in the case for over thirty years and who was over six feet tall, to make himself appear both shorter and thinner than he actually was."
Analysis:
No one knows what any of the suspects weighed at the time of the killings. Arthur Leigh Allen was less than six feet tall. Mr. Allen is still the prime suspect!
