We now know that Art Allen was checked by DNA , finger and palm prints. We can exclude Allen from our list. I do feel that Barbara Parkin could be a Z victim. I don't agree with LE on how a log was put on top of her body. I believe the killer/killers put that log on her so she wouldn't float away and not be found. I would like to know if LE ever compared the 9 mil bullets to the two other Z 9mil. used in his crimes ?
I am not sure if I ever brought up the fact that there were a lot of murdered or attempted murders of nurses in the Zodiac case ? We had Donna Lass, Kathleen John's.
Possible Z victims, Judith Hakari, Carol Hilburn, Rosa Vasquez were nurses, Susan Dye worked at a Hospital in Santa Rosa. I think we can add Barbara Parkin to that list. Maybe Zodiac was treated at one time by a not so nice nurse ?
