OK so the letter thing:
I think she wrote it TO someone (snail mail to prisoners was the very first thing I thought of). There were 2 people in jail she could have written:
Tj
Derek.
She also had a bf at the time that was in and out of jail, who lived in another state.
Now, the letter to Wendy couldn't come from another prisoner unless she wrote one letter out to a civilian who then repackaged the letter and sent it to another prisoner. It's forbidden for inmates to write one another directly.
So, a letter Brittney wrote was found at Wendy's. Sounds to me like Wendy knew of 1 letter and went to retrieve it - possibly being the reason for the confrontation or whatever it was that happened, to Brittney. She never destroyed it and why - we don't know.
She most likely had no idea there's a 2nd letter out there, hence the warning. I'm starting to think the 1st letter (the one that was in her house) was possibly found by Chessie or Paul. (could he be the one writing to wendy?). I could so so so see chessie giving that letter to Wendy after she found it.
I honestly believe that the gun wasn't Brittney it was planted. I've thought that since day 1.
I have always believed that Jennifer and Wendy went out to Styx and killed Donald (which is why they found him so easily and before he expired). That's why they were involved in albi's, cleaning up cell phones and FB's.
Follow me:
Chessie finds the letter. She talks to Paul about this, and then Wendy. Wendy and Chessie confront Brittney over it and Donald is called by Brittney to get her out of the house. The argument and confrontation that Chessie tells is true but TURNED AROUND. Donald and Brittney go out to Styx and this is when Wendy and Jennifer, and Chessie get the bright idea to unfortunately kill them both.
Donald possibly meets up with Wendy because the kid is sick and Jennifer is the one that drives Wendy to meet with Donald. One of these women gets in the car with him and shoots him. They plant the gun, and they drive off but decide to come back to "find" him.
My mind is racing and my thoughts aren't forming well, but I'm sure you all get the point. From day 1 I've felt at least Donald's death went down this way. I have always wondered what this mysterious argument and info Chessie has .. I think we know. It was over a letter implicating everyone. I bet she wrote it when she knew that Ronald has went to the police and felt she too was going to be arrested for something. Maybe she toyed with going to the cops as well but was confronted and told not to? Maybe that's why she was scared and there for - wrote a 2nd letter, possibly mailing it someone to hold?
I am wondering if letters, evidence etc isn't buried in that damn yard.
:dunno:
It's been almost a year and a half since Brittney went missing and Wendy still had letters and evidence hanging around! What's wrong with her brain? 
Thank You for Dumbness.
