In a dramatic twist to an already tumultuous custody battle, a Connecticut woman is facing grave allegations of deceit both inside and outside the courtroom. Kristen Hogan, age 33, stands accused of attempting to poison her estranged husband using antifreeze chemicals, alongside a shocking scheme to fake a paternity test involving her nephew.

The poisoning allegations surfaced earlier when Hogan’s husband reported to authorities that he had been hospitalized after consuming wine and iced tea laced with ethylene glycol, a toxic chemical commonly found in antifreeze. According to the husband, these drinks had been left unattended in the refrigerator at home, presumably dosed while he was away. Initially, Hogan denied any involvement but later confessed to the act, as revealed by police sources.

Adding to the complexity of this case, new details have emerged about Hogan’s attempts to manipulate the judicial system during her custody dispute. Court documents indicate that in June 2021, Hogan claimed her estranged husband was not the biological father of one of their children. While his paternity of their daughter was verified in January 2021, questions remained regarding their son, prompting a court-ordered paternity test in March 2023.

The intrigue deepens with revelations from an arrest warrant issued by the Connecticut State Police. It was discovered that Hogan had allegedly substituted her nephew for her son during the April 2024 paternity test. This ruse was uncovered by a private investigation firm, unbeknownst to Hogan, which was hired to shadow her movements.

Investigators provided evidence that Hogan had, in fact, brought her sister’s son to the laboratory for testing. This was corroborated by social media activity identifying the child as her nephew, and further surveillance observed Hogan returning the boy to her sister afterward. These findings have added another layer of complexity to an already convoluted legal battle.

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.
