Black Widow

On this episode of They Walk Among America… Ethylene glycol is a colorless and odorless compound with a sweet taste commonly found in antifreeze. Ingesting a sufficient quantity of it can lead to fluid accumulation in the lungs, organ damage, seizures, and, ultimately, death. The effects of this poison typically manifest within one to twelve hours after ingestion, initially impacting the gastrointestinal tract and central nervous system. Within twelve to 24 hours, ethylene glycol starts affecting the heart and lungs, while toxic calcium oxalate crystals begin to form. After 24 hours or more, the metabolized poison takes its toll on the kidneys, and death becomes possible at any stage. This type of poisoning results in a slow and agonizing demise, yet it often remains imperceptible. One particularly troubling aspect is that antifreeze poisoning does not readily show up on standard toxicology tests. Consequently, if a death doesn't appear suspicious, the presence of antifreeze poisoning may go undetected…
