In this episode, we uncover true tales of marriages turned lethal experiments: from the insidious thallium poisonings by Russian engineer Vataslav Solovio—who silently killed his wife, daughter, and partner—to modern cases like the medical resident who murdered his wife with a gout drug (colchicine) and the attempted bleach poisonings via the coffee maker. You’ll hear unique details such as thallium’s symptoms mimicking common illnesses and the digital sleuthing used to trace colchicine.

Join us as we explore how investigators pieced together forensic evidence—from hair‐loss patterns and toxicology screens to CCTV footage and metadata—and reveal the warning signs hidden in seemingly normal relationships. Learn critical lessons about domestic vulnerability, the need for routine tests in unexplained illnesses, and the psychology of a killer who treats loved ones as lab subjects.
