With a year so full of incredible surprises, which case is next to be solved, Bishop or Zodiac? We're more than a little spoiled these days.

My guess is we'll finally put Zodiac to rest by the end of the year. We have to assume the same method used to catch JJD has been employed for Zodiac by now. I'm amazed we have yet to hear anything about it.

Do they have Zodiac's DNA? I remember they had pulled some DNA off one of his letters, but there is debate whether it was really his DNA and not some contamination from over the years.

Either way, there is almost a 100% chance Zodiac is long dead.

Yeah, I don't think they have any definitive DNA from Zodiac.

Nothing you'd ever be able to get a conviction on, assuming they linked it to a person. It's all apparently contaminated, possibly mixed. $10, Zodiac's not getting caught let alone convicted this way.

Not sure how DNA will solve Bishop’s case. The likelihood with him is that he left the US and is probably dead

As in Brad Bishop?

He killed off his family once, I can't see him starting a new one abroad in between bouts of being a filthy bearded man.

(I don't really have a lot of faith in that Italy sighting anyway)
