[1] His "potential for doing harm" - although we have no cited examples of harm inflicted upon any of the library staff. However, what he potentially could have done, is possibly a cause for concern.
[2] Bragged about escaping over the wall from Patton State Mental Hospital, which doesn't equate to being a murderer.
[3] The library staff member stated "I wish I could remember the poem about the cataloging boss he and I both had. I remember that she did not understand the poem he wrote. I didn't either but was frightened by it". Frightened by a poem you neither understand and can't remember, is terrifying enough on its own
[4] "We could see him from the cataloging department. He was like a statue - always there". Clearly he was a menacing statue - not moving - but an ominous presence nevertheless.
5] "When the murder happened, I stated to my fellow workers that when Ross reappeared on campus (because he was not around the day after the murder), and if he had on different clothes, then he would be guilty in my mind, until someone proved him innocent". I really hope this person never sat on a jury. Whatever happened to those good old values of 'innocent until proven guilty'? Whatever happened to 'beyond a reasonable doubt'? I hereby sentence you to 50 years for buying new clothes.
[6] "Sure enough, it was a few weeks before he reappeared at his spot on the pit wall and he had on a totally new set of clothes". Guilty as charged Sir - how dare you wear a different set of clothes after a few weeks.
[7] "One rainy night after he was back in Riverside, I stopped at a liquor store in Market Street. I pulled up alongside a car that was parked just in front of the store doors. I ran inside but left the doors locked as I always do. When I ran back to my car something told me to do a very strange thing. I ran around to the passenger side and in a flash I had the door open and was inside and the door locked behind me. Just at that instant Ross came from a large hedge in front of my car door and walked between the two cars and out of the parking lot. He did not look at me. Needless to say I drove out of there as quickly as possible". This is called historical narrative building - creating a sensationalized and novelistic reconstruction of events that never happened. The person is selling you a story. Using the introduction of "one rainy night" is unnecessary to the story, used for dramatic effect. She just happened to pull up to a liquor store where Ross was hiding behind a bush in the rain, then coincidentally "something told her to do a very strange thing" - get in the wrong door of her vehicle, just before Ross "instantly" emerged from a large bush. What told her to do a very strange thing? - a sixth sense of impending doom, before she raced away fearing for her life. The fact of the matter, is that nothing happened - and if Ross Sullivan was there, he was likely just walking by without even noticing her. Had he glared at her menacingly from his sodden, furrowed brow, with dastardly intent, the story may have been a bit more compelling. Or, if he had he leaped from the bush wielding a dripping axe and mumbling incoherently.
[8] "Ross apparently parked a motorbike close to one of the faculty members car each day during the fall of 1966. That faculty member also put Ross at the top of his list as a suspect in the murder. Didn't apartment residents near the murder site recall hearing a motorbike start up just after the screams". No they didn't, so it is probably advisable to read up on the facts of the murder, before establishing Ross Sullivan at the top of your suspect list - guilty of parking his motorbike close to a car in the parking lot. Was it menacingly close, bordering on threatening? Did it get closer each day, inching to a dramatic conclusion? Was it raining each day?
[9] "There are half dozen or so of us at Riverside City College that agree on a suspect - but it isn't one that the police are interested in". I will probably side with the police on this one, who actually did a proper investigation and stated he had an alibi. On the flip side, the library staff may have a compelling case to bring to court - Ross Sullivan was smelly, changed his clothes at least once, allegedly hopped from a bush in the rain without an axe, threateningly parked his motorbike in the campus grounds, wrote poems nobody can remember and moved as fast as a statue, apart from when he was vaulting mental hospital walls. In his spare time he murdered five people in the Bay Area, despite the fact nobody can place him within 75 miles of any crime scene. On a rainy night, maybe he rode stealthily into the Bay Area on his old Triumph motorbike four times, placing the executioner's costume in the top box on September 27th 1969 for the return journey to Santa Cruz. Or maybe some evidence would help.
