the sister of the first woman killed, since they had solid evidence that the zodiac knew her prior to killing her and that her sister said there was a creepy guy who liked her.

shareGood point. Seems an obvious step. Were the police worried though that it would reveal their 'partnership' with Graysmith? Only getting the idea by letting a civilian see confidential files? Seems like he was only one who thought Zodiac knew the first victim.
