Shirley Allen: Her Obsession with Murder for Money

Last week, I presented the sad case of Tera Smith. Tera was only sixteen when she vanished from Redlands, California. More than twenty years later, her disappearance remains unsolved. This week’s case is that of the many-married Shirley Allen. In 1982, Shirley poisoned her sixth husband with ethylene glycol. She probably poisoned at least two of her previous husbands as well, one fatally.

Shirley Allen entered the world as Shirley Elizabeth Goude in 1941 in St. Louis, Missouri. Little information exists about her early life, but she was obviously unlucky in love. She married a total of six times to five different men. Several of her husbands developed health problems shortly after the wedding.

In October 1968, Shirley married her first husband, Joe Sinclair. Eight months later, Shirley tried to get rid of him with rat poison. Sinclair informed authorities, but they did not file any charges. Instead, Sinclair wisely divorced Shirley and got away from her.

Shirley married for the fifth time in 1977, when she wed John Gregg. The following year, after being married to Shirley for less than twelve months, Gregg collapsed and died. Initially, authorities ruled it a natural death. Shirley had hoped to collect on Gregg’s life insurance. She was furious when she learned he’d recently changed the beneficiary of the policy, leaving her nothing.

Shirley Allen Poisons Husband Number Six

Lloyd Allen married Shirley in 1981, her final spin of the matrimonial wheel. Lloyd’s health soon began a precipitous decline. When he complained that his drinks tasted “off,” Shirley explained she’d added iron supplements “for his health.” Unfortunately for him, he took her at her word. Lloyd Allen died on November 1, 1982, leaving behind a $25,000 life insurance policy.

Whispers about the unnatural nature of Lloyd’s death began to circulate. An autopsy determined Lloyd’s body contained a lethal amount of ethylene glycol. Ethylene glycol is a sweet-tasting, odorless substance. It is the main ingredient in automotive antifreeze and is a deadly poison if ingested. With an autopsy confirming foul play, police arrested Shirly on November 6.

Shirley Allen went on trial two years later in Rolla, Missouri. Her two daughters from a previous marriage, Norma Hawkins, 18, and Paula Hawkins, 17, agreed to testify for the prosecution if they didn’t seek the death penalty. On the stand, the girls testified they’d seen Shirley put antifreeze in Lloyd’s drinks. They also said Shirley sent them to buy antifreeze so she could “finish him [Lloyd] off.” And they further testified that their mother sent them to look for tainted Tylenol capsules in the wake of the infamous Chicago Tylenol poisonings.

Epilogue

It took the jury less than three hours and only three votes to convict Shirley Allen of first-degree murder. With the death penalty off the table, the judge sentenced her to life in prison without the possibility of parole for at least 50 years. Shirly died in prison on April 2, 1998. She was 56 or 57 years old (her exact birthdate is uncertain).

Some sources report that another husband, Daniel Null, died mysteriously. Authorities exhumed the body, but an autopsy failed to reveal proof of ethylene glycol poisoning.

The Discovery Channel series Evil Lives Here featured the Shirley Allen case in Episode 11 of Season 5, Poisoned by Love.
