I see evidence that the kidnapping could have been staged (or SP's version of it, at least):
1. Pictures of family just a few days before the disappearance, with the entire family wearing bandannas and two of them with bandannas covering half of their faces.
2. Cell phone found with earbuds neatly coiled on the phone.
3. SP's history of blaming others for injuries that may have been self-inflicted. (You may say this is not a clue, but if anyone checked my history, they would not find a call to police in which anyone said I injured myself and blamed someone else for it).
4. SP's mother posted on FB about the presidential election and other matters, while SP was missing. Very peculiar behavior. Would you be able to do that if your daughter went missing and a huge search was launched to find her? Only if you know things weren't as they seemed, right?
5. SP seems to have selective memory about what happened during the 22 days. She can remember smashing one of their faces into the toilet, but can't remember what the vehicle looked like and took a year to remember enough about her captors to produce a sketch.
6. No motive. SP doesn't even know the motive.
7. Bound with one hand free.
8. LE being elusive on several matters, including the extent of SP's injuries compared to what KP said about them. LE pointing out inconsistencies in SP's story, like the cut on her foot she says she sustained, but wasn't there.
9. KP said to his kids, "she will be home by Thanksgiving". (I do not think KP was involved in SP's disappearance, but I do think he knows why she disappeared.)
10. SP shows up on Thanksgiving! This stands out to me more than anything else. Even if KP hadn't mentioned the holiday to his kids, the fact that SP could re-appear, alive, the survivor, on Thanksgiving morning, is very suspicious to me.
11. She was not sexually assaulted. (Again, what was the motive if not sex or ransom?)
12. LE has never been concerned that others might be in danger from the two Hispanic women, even though they don't know the motive, and the women are still out there. This makes absolutely no sense, no matter which way you twist and turn it.
13. SP texting with another man with plans to meet up, prior to her disappearance. That man has been cleared, but this is evidence that SP lived part of her life on the sly.
14. A prior internet entry by a Sherri Graeff (SP's prior husband is adamant that SP didn't write it) that states she had to constantly defend herself against Latinos in high school, a group of Latino girls would "constantly rag and attack" her, she had to "constantly stick up for herself instead of knuckling under what the Latino girls said and wanted", a Latino girl took a swipe at her and SP "lunged back at her, slamming her head between the bleachers" (sound familiar?) This is WAY TOO coincidental.
15. Also stated in this blog post: "on the way up the bleachers when I had rebuffed the Latinos, I had split my leg open and it was hard for me to walk. But when my dad picked me up from the police department, the only thing he kept saying to me was, "Sher, I'm proud of you. You did the right thing. Keep on walking. Don't let your leg slow you down. Keep walking."
You say you can't fake the love seen in Papini family pictures. ANYONE can fake love in pictures, posts, etc. We see it all the time on FB. People want to paint the picture of a happy family when what really happens is a completely different story.
You also suggest LE might have instructed SP to stay quiet. But in the latest press release, they say SP and KP are free to talk. They're not doing it, perhaps because they have no answers for so many questions.
