Shirley Allen is arrested for poisoning her husband, Lloyd Allen, with ethylene glycol, commonly known as anti-freeze. After witnessing her mother spike Lloyd’s drinks with the deadly substance, Shirley’s own daughter turned her in to the authorities.
Lloyd Allen was Shirley’s sixth husband and the second to die from mysterious causes; the other four had divorced her. John Gregg, who died a year after he married Shirley in 1977, had changed the beneficiary on his life insurance policy shortly before his death. Shirley was outraged to find that she was left with nothing.
Lloyd, who is said to have complainedof a strange taste in his beverages, believed Shirley when she said that it was an iron supplement for his health. However, Joe Sinclair,one of Shirley’s previoushusband,had beena bit more suspicious. When his coffee tasted odd on several occasions, he went to the police. Although he suffered internal injuries, no charges were ever filed. Instead, he filed for a divorce.
When Allen’s death was investigated, toxicology reports confirmed that his body tissue contained a lethal amount of ethyl glycol. After a short four-day trial, Shirley Allen was sentenced to life in prison in 1983.
