For people who want a refresher on the case, or for those who haven't seen it, I found the article from a 2001 February issue of Spin magazine that is about Zebb's disappearance:
“The Vanishing”
Sorry if there are issues with the link or viewing it; I know it's on Google books, and a bit hard to navigate. The article is on page 91. If for whatever reason it doesn't work and a bunch of people would be interested in reading it, I could transcribe and post it here. Anyway, the quote at the end of the article by Owens is chilling. He talks about a woman who told Zebb's sister she had "psychic" visions in her dreams of Zebb and that he would be found under a set of jagged rocks by a source of water in like a giant field/valley area, and though the tip didn't lead to anything, Owens coworkers at Volvo teased him about it. One day they stuck a glove under rocks behind the factory and jokingly told Owens that it was Zebb. His coworkers also called him "Killer" as a joke too; if only they knew how right they were. Creepy.
I wouldn't be surprised if Owens killed Zebb, and has tried to frame Wes and Misty various ways. Maybe the entire story of going to look at a car was a ruse, a way for Owens to get Zebb alone, with a large amount of cash, in a remote area. Perhaps he had a (female?) accomplice who sent the page, which would cast suspicion from Owens; maybe this same person then also helped in moving the car to the location it was found, hoping it would be another red herring for investigators. The lips drawn on the back window look very much like something a young woman would draw; that "style" reminds me so much of bubble writing, the kind some girls in high school had – plus the fact that girls use that window chalk all the time to write on their friends’ cars for graduation, or sports, etc. Maybe it wasn't supposed to be interpreted in order to find Zebb, but was purposely vague, confusing, odd, to intentionally confuse and distract LE from someone else. The only "message" I see in it is perhaps "puppy love", like the love Zebb may have felt for Misty. This case is so strange; I really, really hope we are coming closer to getting some resolution to this case, and justice for Zebb and his family. He seemed like such a sweet, thoughtful, caring young man. He didn't deserve this.
Sorry for the ramble – like I said, these are just my thoughts and opinions. Let's hope that justice comes soon!
