It's been four years since father of three, Eric Richins, died from a fentanyl overdose. We now know his ingestion of the drug was planned by his wife Kori.  Afterwards, she wrote a children’s book about grief,  with her children, to help them cope.   Kouri Richins' book  isn't the only thing she's written.

There's a six-page handwritten letter, "the walk the dog letter."  Prosecutors say that in the letter, Richins is instructing he family how to lie about what happened the night her husband died.  

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

The jury deliberated just under three hours before convicting  Richins of aggravated murder, attempted aggravated murder, forgery and two counts of insurance fraud. 

What happened to the Richins children?
