A 33-year-old woman who tried to poison her estranged husband with antifreeze has been charged with attempted murder.

Kristen Hogan of Ridgefield, Connecticut, was taken into custody on Friday and charged with allegedly adding antifreeze to a wine bottle and iced tea at her husband’s residence.

The pair have been locked in a bitter custody battle relating to their child. 

On August 10, her 34-year-old husband drank a small amount of spiked wine and kept waking up sick in the middle of the night.

The next day he began to vomit, according to documents released by the Connecticut state police.

The victim called his mother, who arrived to find her son slurring his words, staggering, and vomiting.

The father was rushed hospital, where first responders initially thought he was experiencing a stroke.

They soon came to realize he was suffering from ethylene glycol poisoning, an ingredient in antifreeze.

The husband was hospitalized in the ICU, where he underwent dialysis due to kidney failure. Doctors inquired about his recent intake, prompting him to mention the wine.

Ridgefield Police detectives seized the wine and submitted it to the Connecticut Forensic Laboratory for further testing.

He quickly suspected Hogan’s involvement in the poisoning when he discovered she had accessed his Wi-Fi while he was away from home.

Although it appears they do not live together, Hogan had full access to the home.

In discussing his suspicion with detectives, the man explained that Hogan stood to gain full ownership of the house and full custody of their child if he was out of the picture.

Authorities reportedly uncovered online searches on Hogan’s phone for substances like potassium cyanide, potassium ferricyanide, citrate-cyanide, potassium thiocyanate, and monoethylene glycol.

However, during initial questioning, she denied knowing what the chemicals were.

Additional searches for how much of these substances a person would need to ingest to die were also found, according to the documents.

Hogan initially denied having any knowledge of the incident or involvement

When detectives questioned the husband about his belief that Hogan was responsible, he noted her potential to acquire the house completely and gain full custody of their child.

Hogan later remembered she purchased monoethylene glycol on Amazon because she was ‘using that specific chemical to clean the carpet at her mother’s house,’ and said the substance never left her parents’ home.

When detectives confronted her about the bottle of wine and her husband testing positive for the substance, she initially denied the claims.

Still, she allegedly said, ‘she never wanted to kill him but just wanted to make him sick as payback for being mentally abusive.’

Hogan then said she didn’t know how much of the chemical she poured into the bottle of wine.

Detectives told Hogan that their child may have potentially consumed some of the poison, which she denied being possible.

The documents also noted that, before his wife’s arrest, she began acting more cordially and offered to come over and cook something that was out of the ordinary for their relationship at the time.

Hogan was charged with two counts of attempted murder and one count of interfering with an officer.

She is being held on a $ 1 million bond.
