A custody dispute in Ridgefield has escalated into a criminal attempted murder case, following the arrest of a woman accused of poisoning her estranged husband with a chemical found in antifreeze.
Kristen Hogan, 33, of Ridgefield, was arrested on October 2, 2025, and charged with two counts of Criminal Attempt at Murder and one count of Interfering with an Officer.
The charges stem from an investigation by the Connecticut State Police Western District Major Crime Squad (WDMCS) into the poisoning of her former partner, who was hospitalized in August with ethylene glycol in his system. Ethylene glycol is a toxic substance commonly found in antifreeze.

Hospitalization and Investigation
According to the arrest warrant application filed in Danbury Superior Court, the male victim was hospitalized on August 10, 2025, after becoming seriously ill at home. He had consumed a small amount of an opened bottle of wine that had been recorked and placed in the refrigerator on August 5, 2025. The victim reported waking up repeatedly on the night of August 10, experiencing increasing illness, vomiting, and slurred speech.
Hospital doctors initially suspected he was having a stroke, but testing indicated he was suffering from ethylene glycol poisoning. He was subsequently placed on dialysis and admitted to the Intensive Care Unit (ICU).
The investigation focused on Ms. Hogan after the victim told detectives he believed she was the only other person with access to his residence after the wine was opened. The victim reported that he and Hogan were locked in a custody dispute over their child and that Hogan was seeking full ownership of their home, which he believed provided her with a motive to poison him.

Alleged Tampering and Evidence
Detectives learned that on August 7, 2025, the victim had been waiting at Danbury Superior Court for a meeting with Hogan regarding a complaint she had filed, but she never arrived. While waiting, he received a notification on his phone that Hogan’s cell phone was uploading data to the Wi-Fi router at his residence, indicating she had been at the home while he was at court.
An initial laboratory test of the wine bottle seized from the victim’s home did not detect ethylene glycol. However, the victim’s medical records documented that doctors at the hospital had received verbal confirmation of the presence of ethylene glycol in the victim’s blood, with levels of seven (7) and four (4) being conveyed verbally to aid in immediate treatment.
A medical professional later clarified that for an official lab report, any level below ten (10) would be reported as “not detected,” which correlated the doctors’ notes and the final report.
Hogan’s alleged actions after the poisoning incident also led to the “Interfering with an Officer” charge. The victim stated that after his release from the hospital, he installed interior surveillance cameras due to fear for his life. On September 5, 2025, Hogan allegedly arrived at the home and was seen placing electrical tape over the lenses of the interior cameras.
Hogan’s bond was set at $1,000,000. She is currently scheduled for an appearance in Danbury Superior Court.
