Til Death Do Us Part

Til Death Do Us Part is the title that was given to the sixth episode of Forensic File's fourth season which was first broadcast on November 10, 1999.

Summary
In Pennsylvania in 1991, Robert Curley was diagnosed with Guillain–Barré syndrome when he arrived at the hospital with excruciating leg pains. However, doctors became suspicious during Robert's second admission and tested him for Thallium poisoning, which proved positive, and Robert died shortly thereafter.

Investigators also discovered that Robert's wife Joann Curley was waiting to collect her previous husband's life insurance (from his accidental death) and disagreed with the way Robert wanted to spend it. Joann would then collect additional life insurance if Robert suffered from an accidental death. Joann was arrested five years later, confessed, and pleaded guilty to murder.
