Kouri Richins book on how to deal with grief, isn't the only thing she's written.
There's a six page handwritten letter that's sparking debate, "the walk the dog letter." Prosecutors say that in the letter, Richins is teaching people how to lie about what happened the night her husband died. Her defense team says the letter was privileged information and wants the prosecutors to be sanctioned.
It's called the "walk the dog letter", since that phrase is written in big letters on the top. In it, Richins makes the claim that her husband Eric was addicted to drugs, that he would make frequent trips to Mexico to get pills, and that his death was an accidental overdose. The letter was written to Richins mother, and it reportedly tells her to instruct Richins brother to make the connection to Mexico and drugs when he talks about the case.
The question the court has to answer is, does a defendant attempting to help coach someone on what they should say on the witness stand, rise to the level of Witness Tampering. Prosecutors say it does rise to the level of witness tampering because there is no connection between Kouri Richins' brother and drugs from Mexico. The prosecution believes, again, that Richins is instructing people to lie. That is why the prosecution is asking the judge to disallow contact between Richins and her mother.
