HARTFORD, CT — A Ridgefield woman facing a custody battle with her estranged husband is accused of poisoning his drinks with a chemical found in antifreeze.

Kristen Hogan, 33, is charged with two counts of attempted murder and one count of interfering with an officer after she allegedly mixed ethylene glycol into her estranged husband’s drinks.

The victim, whose name was redacted from Connecticut State Police documents, fell ill on August 10 after drinking from a bottle of wine he had opened five days prior. The man told investigators he believed Hogan poisoned the wine on August 7, the same day he was to meet her for a court hearing she never attended.

The husband said that while he was at court, he received an alert on his phone. The alert showed Hogan’s cellphone was uploading data to his Wi-Fi router.

The man told police that Hogan, with whom he has a child, has “unrestricted access” to the home. He accused Hogan, saying she was the last person to be in the house before he drank the opened wine.

The man drank a small amount of the wine on August 10. By the middle of the night, he woke up multiple times and became increasingly ill, the warrant says.

At 6 a.m. the next day, the victim woke up vomiting and called his mother. The mother arrived and found her son slurring his words, staggering, and vomiting, according to the document.

The mother rushed him to the hospital. Doctors initially thought he was having a stroke. That diagnosis was dismissed after doctors said he was showing signs of ethylene glycol poisoning, an ingredient in antifreeze. He was immediately placed on dialysis.

The victim told police Hogan’s motive was that she would become “the full owner of the residence and gain full time custody of their child,” tags reported by WFSB.

Investigators discovered searches on Hogan’s cellphone for several chemicals, including potassium cyanide, potassium ferricide, citrate-cyanide, potassium thiocyanate, and monoethylene glycol. Searches for how much of these substances “would kill you” are also present, according to NBC CT.

When confronted by police, Hogan first denied any wrongdoing. She initially claimed she was confused about the chemicals and then stated she recognized the word cyanide from the television show “Psych,” the arrest affidavit noted.

She did admit to buying a bottle of monoethylene glycol in July. She insisted she was using that substance to clean carpets at her mother’s house.

Hogan eventually confessed to mixing the monoethylene glycol into her estranged husband’s wine, according to the arrest affidavit. She stated she didn’t know how much of the poisonous liquid she put into his drink. She said she just poured it into the nearly full bottle of red wine.

Hogan finally admitted she mixed the monoethylene glycol into her estranged husband’s wine, the arrest affidavit stated. She said she did not know how much of the poisonous liquid she put in the nearly full bottle of red wine.

Both the wine and a bottle of iced tea tested positive for ethylene glycol. Police say Hogan poisoned the iced tea on a separate day from when she tampered with the wine.

The child Hogan and the victim share went to the hospital in late September with symptoms like those the father experienced. When police asked Hogan if her child might have ingested the ethylene glycol, she “adamantly denied” it, the arrest affidavit said. Hogan stated that she tampered with only the wine and the iced tea, and no one else knew about it.

Hogan allegedly told police she never intended to kill her husband. She said she wanted to make him sick as “payback for him being mentally abusive.”

Hogan was arrested on October 3 and charged with two counts of criminal attempt at murder. She was held on a $1 million bond. The investigation is ongoing.
