Bryan Hartnell stated that the assailant wore a black hooded mask made of a cloth material, covering his entire head and shoulders, reaching down to the waist. On the front of the four cornered mask at the chest area was a white circle (3 x 3 inches in diameter) and a symmetrical cross. He would further elaborate on the design of the crosshairs, as well as later in the 2007 Zodiac documentary, stating "It looked like it was made with a machine or with some degree of care- it wasn't just scrawled on with white paint. It was proportional."
That was my mistake. I meant "stitched on". I know that Hartnell said that the costume looked like it was made with a machine. I assume he meant a sewing machine?
Another interesting detail is that the circle was only 3 inches in diameter. Most people think of the symbol being emblazoned across the entire front of the costume, when it fact is was quite small.
Lastly, I don't recall Hartnell saying that the costume reached down to the waist. Can you provide a source?
The effort should always be to try and eliminate suspects not to confirm them.
