Hello, my name is Mark, and I currently live in the San Diego area. I’ve been interested in the Zodiac case since youth (I was 6 in 1968) and my interest has not dimmed with time; B.S. degree in Accounting/Economics; good critical thinker; usually have good problem solving skills and insight; still familiarizing myself with the case; have initial questions regarding Ross Sullivan; Where has the interest in him been all this time? how come, that is, it seems so recent? I literally had never heard of him until visiting your site (a dearth of info on the web about him), and he is an intriguing POI; fits the physical description and psychological profile, being not inconsistent with one capable of committing such crimes; anyway, hope we can get more info on him. Other than that, will keep abreast of the posts and hopefully can add something to the discussion.
Welcome, Mark!
I am also interested in Ross, and any new information about him that can be uncovered. I am also open to any number of other possible POIs. Lots of good discussion here. Sounds like your background might give you a foundation in logic, I look forward to your contribution.
Hi valleylife/Mark…
Good to have you. Nice to have more "critical thinkers" among us. 
“…they may be dealing with one or more ersatz Zodiacs–other psychotics eager to get into the act, or perhaps even other murderers eager to lay their crimes at the real Zodiac’s doorstep.“ L.A. Times, 1969

Lol! Thanks, Tahoe27. I do my best.
Great to have you aboard Mark!
Ross is my favorite suspect, but he’s not really a new Suspect.
Several years ago, a reporter was interested in Ross as a Suspect and had been in touch with Joann Bailey the school Librarian at RCC when Cheri Bates was killed there. She shared this info with the reporter and also with Howard Davis, but it sort of went no place. Details were sketchy, and then he got really cold as a Suspect.
It wasn’t until a year or two ago, when i was doing an ‘audit’ of every name ever mentioned as a Suspect when I decided to dig into Ross a bit more, and as soon as I found his high school, and then saw his photo,I was blown away by his likeness to Zodiac. In short, he was a Guy that could 100% be placed in the Riverside Library during the period when Bates was killed, and he looked identical to the Z sketch. To date, he is the only POI ever to be confirmed in that RCC Library,and looking identical to the sketch is just the cherry on the Sundae. Add in his mental illness, his physical description, and his timeline, it’s hard not to like him. As much as we know about Ross, there’s a bunch we don’t know.
Anyhow, welcome aboard!

Welcome aboard VL.
This is where I’m really glad I decided on a ‘handle’ policy (for myself anyway). So from me it’ll be VL.
For one it’s shorter (yes I’m thatlazy) but also because Mark is my real name too and I don’t know about anyone else but when I meet people with the same name as myself I feel like I’m addressing myself in the third person when I’m referring to or addressing them.

Z (Ross?) is certainly my lead suspect in the Bates’ homicide, but Barnett can’t be ruled out either. This is, of course, assuming either z is the author of the confession letter or the glancing reference in a later known z letter about his "earlier activity" is to Bates (pretty likely) or both. z, though he may have exaggerated his number of vics, and not followed through on many of his threats, appears not to be one to take credit for crimes he was suspected, but not guilty, of. The desktop poem, which likely is z’s, at least strengthens the presumption that z was in Riverside at this time and should at least place him high on the list of suspects.
As regards the confession letter, despite its being slightly out of character for z, the identical misspellings of "choaked" and "twiched" in other known z letters, plus the same pathological "mood" of the confession leads me to conclude it’s his. Not sure if this is so, but the case would be especially good if the confession letter was published subsequent to z’s correspondence which include the same misspelled words.
