Connecticut Woman Charged in Chilling Attempt to Poison Estranged Husband with Antifreeze-Laced Wine

A Connecticut woman is facing grave charges after allegedly attempting to poison her estranged husband by lacing his wine with antifreeze. The shocking allegations detail a calculated plot that unfolded amid contentious divorce proceedings, sending a chill through the community.

Catherine H.

Montgmery, 52, of Higganum, was arrested and charged with criminal attempt to commit murder and first-degree assault. Authorities began investigating in February after her estranged husband, David H. Montgmery, reported a disturbing pattern: he had noticed a peculiar taste in his wine over several weeks and began experiencing concerning health issues.

According to court documents, David Montgmery grew suspicious of the strange, sweet taste in his nightly glass of wine.

His health deteriorated, prompting him to purchase test strips designed to detect antifreeze, also known as ethylene glycol, in liquids. To his horror, the test strips reportedly indicated the presence of the toxic chemical in his wine bottle.

Further investigation by law enforcement revealed compelling evidence.

Surveillance footage reportedly captured Catherine Montgmery handling a bottle of her husband's wine. The symptoms experienced by David Montgmery were also consistent with ethylene glycol poisoning, which can cause severe kidney damage, neurological problems, and can be fatal if ingested even in small amounts.

The couple was in the midst of a contentious divorce, a detail investigators believe may have served as a motive for the alleged poisoning attempt.

Divorce cases, especially those involving significant assets, can often become emotionally charged, but few escalate to such extreme and dangerous levels.

Catherine Montgmery was held on a significant bond, reflecting the severe nature of the charges against her. The case underscores the devastating potential for domestic disputes to turn deadly and highlights the insidious methods some individuals may employ.

As the legal proceedings unfold, the community awaits further details in this deeply disturbing alleged crime.
