FARMINGTON, N.Y. – Authorities say a western New York woman accused of lacing a jug of margarita cocktails with antifreeze told them she wanted to punish her boyfriend for being emotionally and physically abusive. But she says she didn't intend to kill him.
Thomas Stack, a former Air Force airman, was being treated for alcohol abuse at a Veterans Affairs hospital in 2007 when he met Cynthia Galens. She was a clerical assistant struggling to cope with her teenage son's recent death from a drug overdose.
New details are emerging about their troubled relationship, which ended with Stack dying in October from complications of ethylene glycol poisoning. Galens was charged with murder this month after police said she confessed to spiking a margarita mix with antifreeze.
