NY woman found guilty of fatally poisoning boyfriend with antifreeze mixed into margaritas

CANANDAIGUA, N.Y. – A woman has been found guilty of manslaughter in death of her boyfriend, who drank a jug of margaritas laced with antifreeze at their apartment in western New York.

Air Force veteran Thomas Stack died last year from complications of ethylene glycol poisoning.

Cynthia Galens was convicted of first-degree manslaughter Thursday after a four-day trial. The 52-year-old Galens faces five to 25 years in prison at sentencing scheduled for Nov. 10.

Investigators say Galens told them Stack was emotionally and physically abusive and she decided to exact revenge by pouring a shot glass of the toxic chemical into a margarita mix. Stack died four days later.

CANANDAIGUA, N.Y. (AP) — A jury has gotten the case of a woman accused of killing her boyfriend by lacing a jug of margarita cocktails with antifreeze at their apartment in western New York.

Cynthia Galens was charged with murder in January, three months after Air Force veteran Thomas Stack died from complications of ethylene glycol poisoning. But a grand jury opted in February for a less severe first-degree manslaughter charge.

The 52-year-old Galens has been on trial for four days. The trial began Monday.

Investigators say she told them Stack was emotionally and physically abusive and she decided to exact revenge by pouring a shot glass of the toxic automotive chemical into a margarita mix. Stack died four days later.

Galens says she intended to make him sick, not kill him.
