In a bizarre twist of events, a Connecticut woman embroiled in a custody battle is now facing allegations of attempting to poison her estranged husband and manipulating a paternity test. Kristen Hogan, 33, stands accused of using antifreeze chemicals to spike her husband’s beverages during their ongoing dispute over child custody.

Reports from Law&Crime detail how Hogan allegedly laced her husband’s wine and iced tea with ethylene glycol, a substance commonly found in antifreeze. The husband recounted to investigators his suspicion that Hogan tampered with his drinks while he was away, leaving them in the refrigerator for him to drink. Following the incident, he required hospitalization. Initially, Hogan denied any wrongdoing but later confessed to the act.

Adding another layer to the saga, authorities have uncovered a previous deception by Hogan aimed at keeping her husband away from at least one of their children. This involved falsifying paternity test results by substituting her nephew for her son during testing.

According to an arrest warrant shared by the Connecticut State Police, Hogan, a mother of two, claimed in June 2021 during a custody hearing that her husband was not the biological father of their children. While a test in early 2021 confirmed his paternity of their daughter, doubts lingered about their son, prompting the court to order a paternity test in March 2023.

In April 2024, Hogan reportedly took her son for the court-mandated paternity test. However, unbeknownst to her, a private investigation firm had been engaged to monitor her actions. Their findings revealed that Hogan had actually taken her nephew to the lab instead of her son, according to the arrest warrant.

In addition to identifying the boy as Hogan’s sister’s son on social media, the investigators noted that the boy they had seen with Hogan at the lab that day was later returned to Hogan’s sister, who was also surveilled.

“During this period, the younger male child that had been observed at the appointment location was observed and overheard by [an investigator] addressing the subject’s sister as ‘Mommy,’” the report said. The report noted that the boy’s words “can also be lip read on the video that was being taken at the time.”

The investigators’ report said that Hogan’s mother accompanied her to the lab, but stayed in the car while Hogan went inside. The investigators said that neither Hogan’s sister nor her mother seemed to be aware that Hogan allegedly used her nephew for the paternity test — and that they were not happy when they found out about it.

“[Hogan’s sister] stated that she was unaware her children were brought to [testing company] Paymer and Associates on 04/23/2024,” the report said, conveying a conversation between an investigator and Hogan’s sister that took place on Monday. “[Hogan’s sister] stated she learned of this issue through reading court documents and upon discovering that her children were used to falsify a DNA test she became angry. [Hogan’s sister] stated that since she became aware of the entirety of this situation, she has had minimal contact with Kristen Hogan. I asked if she believed [Hogan’s mother] was aware of what Kristen Hogan planned on doing that day. [Hogan’s sister] stated she believed her mother did not have any knowledge of the situation.”

A lawyer for Hogan’s mother also told police that the mother “was unaware that Kristen Hogan planned to bring her sister’s son to get a DNA test,” the warrant says.

A former boyfriend of Hogan’s — who had lived with her and her children — also identified the boy taken to the lab as Hogan’s nephew, and not her son.

After a December 2024 hearing at which the surveillance footage was shown, the warrant says, the judge “ultimately determined that Hogan was not presenting a truthful testimony” about the DNA test.

Hogan has now been charged with perjury and tampering with evidence. According to police, Hogan turned herself in on Thursday and posted $50,000 bond. She is scheduled to appear in court on Dec. 23.

Hogan’s attempted murder case is still pending. According to the case docket, her next court date is Jan. 27, 2026.
