No one suspected that the woman he had trusted for decades was quietly planning his death.

This week on Pathology with Dr. Priya, a "Zone 7" series, Sheryl McCollum and Dr. Priya Banerjee discuss the case of Marcy Oglesby, who, over several months, secretly mixed over-the-counter eye drops into Young's food and drinks.

When his body was later discovered inside a storage unit, toxicology revealed lethal levels of tetrahydrozoline, the active ingredient in common eye drops.

Dr. Priya explains how this drug attacks the cardiovascular system, why it is almost undetectable without targeted testing, and what makes poisonings like this so difficult to identify until it's far too late.
