Hi, crime junkies. I'm your host, Ashley Flowers. And I'm Britt. Last episode, I walked you through the first five months following the death of Mary Yoder. 60-year-old Mary was happy, healthy, and beloved by her friends, family, and patients near Utica in central New York, where she and her husband Bill were chiropractors with their own practice.

But out of nowhere, one Monday afternoon in July 2015, Mary became violently ill.

Her son had been sick with the same symptoms a few months before, and it took him a while to heal, but he had.

So initially, she and her husband thought that this was the same thing, some kind of stomach bug. But in less than 48 hours, Mary was dead. And when toxicology results came back,

they revealed something no one knew while she was alive. Mary had lethal levels of a drug

called colchicine in her system, a gout medication that she had no reason

to be taking. As it became clear that Mary was poisoned, suspicion fell on her husband Bill,

who had started a relationship with one of Mary's own sisters just two months after his wife's

death.

But just as detectives were getting started, an anonymous letter arrived at their office,

pointing the finger at someone else entirely.

The tipster claimed that Bill and Mary's 25-year-old son Adam had killed her and that there was proof. The Colchicine bottle was still in Adam's Jeep,

the letter said. And sure enough, when police went looking, there it was with the receipt of purchase

emailed to Mr. Adam Yoder1990 at gmail.com. It all seemed a little too perfect for Oneida County Sheriff's, Lieutenant Robert Nelson,

and investigator Mark Van Amie. An anonymous letter that just happened to lead them right to the evidence,

they had to wonder, was someone trying to frame Adam? And if so, who? His own father? Police clearly didn't have a

full picture of this family yet, so they brought in one person who knew all of these players,

22-year-old Caitlin Conley. Katie had dated Adam on and off for years, and she was the office manager

at Bill and Mary's practice.

But she was more than an employee.

Mary considered her family.

She was even mentioned in Mary's obituary.
