Stella Nickel's Plan to Kill Her Husband

Stella Snow killed her husband Bruce in 1986 by poisoning him with cyanide. She created the illusion there was an unknown mass murderer in town, poisoning locals indiscriminately. Investigators understood how fortunate they were when the cyanide was picked up during Susan Snow's autopsy,. Who knows how many other people would have died if that had not been the case? It was an otherwise flawless scheme because of its simplicity and anonymity.
