On July 20, 2015, beloved 60-year-old chiropractor Mary Yoder falls violently ill and is rushed to the hospital. Two days later, she dies, leaving her family and friends in a state of stunned disbelief. When Mary's autopsy report reveals she didn't die of natural causes, and police receive a series of suspicious letters, they realize they've got a murder on their hands. Their ensuing investigation leads to allegations of an eyebrow-raising affair, a suspicious letter, and a surprise arrest. And while Mary's accused killer maintains her innocence, it takes two different trials to determine her fate. In-depth insights from the prosecutor detail how an investigation into an unusual death turned into a murder case, and how digital forensic evidence tied the suspect to the crime.

On the outside, veterinarian Valerie McDaniel and her boyfriend Leon Jacob look like they have it all. But in February 2014, Houston police receive a tip from a conscientious bail bondsman that a murder-for-hire plot is in the works and a woman's life may be in danger. What ensues is a high-pressure police sting operation, the performance of an investigator's career, a staged kidnapping, and a shocking suicide that leads to an explosive trial in which the defendant's own words come back to haunt him. Features interviews with the bail bondsmen who tipped off police, the cop who went undercover to protect the lives of the intended victims, as well as prosecutors and defense attorneys and actual footage from the undercover sting operation.
