American Mother: The True Story of a Troubled Family, Motherhood and the Cyanide Poisonings That Shook the World

This book chronicles the 1986 investigation into Stella Nickell, a Washington state woman who laced Excedrin capsules with cyanide to kill her husband, Bruce, for insurance money. Her actions resulted in a second, unintended death when Susan Snow unknowingly ingested a poisoned bottle from a local pharmacy shelf. Gregg Olsen details the forensic trail followed by the FBI and the FDA, while focusing on the central role of Stella’s daughter, Cindy Hamilton. Cindy eventually came forward to implicate her mother, exposing a history of family abuse and deception that led to the first conviction under federal product-tampering laws.

True crime enthusiasts and readers interested in forensic toxicology read this account to understand the mechanics of a landmark criminal case. It appeals to those who study the psychology of domestic killers and the societal impact of public safety threats. Readers gain a technical perspective on how investigators distinguish between random product tampering and targeted murder. The narrative provides an unvarnished look at the breakdown of familial loyalty and the legal precedents established to protect consumers from lethal pharmaceutical contamination.
