In all honesty I don't give the "lesbian" and "sex" tape much. I think it contributed to Skylar's demise, but I don't think it was entirely the reason and only a small part in it.
I was impressed with Dr. Phil. Usually I don't like to watch it, but he spoke really well to Dave and Mary and I agree with his assessment of SE being a textbook sociopath with her behaviour.
Newsball doesn't impress me much. I appreciate their extra content, but I don't like the way they treat people (Just look at the video of them talking to SE's cousin's parents, calling them "***** *advertiser censored* parents" and things) and how he's pretty much called out everyone who has talked to SE as a suspect. I tried to watch the vlog but I felt it was too rambly. I'm glad his sections on the shows were only one minute too and they didn't go back to him. Even Dave said he was someone who was out of place there (IIRC)
For the record, the funds of the book DO go towards the Neese family. That's been the only reason why I haven't asked for a refund, actually.
Dixie - As far as the weapons, clean-up, clothes, etc, that's never been explained. All the prosecutor said at their sentencing was that they "cleaned up and went back to their lives". They must have discarded some stuff though, as she said they discarded Skylar's purse that she took with her (as far as I know that's never been found, along with her iPod. Her phone was found on her body along with her clothes). There was a rumour that RS had discarded the weapons and clothes in Cheat Lake the next day with her mother, but I am pretty sure Dr. Phil put that rumour to rest. On Dateline it was mentioned that the police issued a search warrant for kitchen knives at SE's house, so I assume RS said they brought the knives home. Skylar's blood/DNA was found in the trunk of the car, which I think was there because of the transporting of knives and possibly their bloody clothes. To this day the cleanup has never been explained. I think the clothes were possibly burned but I think the knives were brought back to the Eddy house.
