Hartford, Connecticut – A 33-year-old Connecticut woman already facing an attempted murder charge for allegedly poisoning her estranged husband is now accused of faking a court-ordered DNA test by presenting her nephew as her son, according to newly released police records.
Authorities say Kristen Hogan tried to manipulate a long-running custody dispute by falsifying paternity evidence years before she allegedly poisoned her husband with antifreeze chemicals, an act investigators describe as “payback” during a bitter separation.
Alleged poisoning amid custody dispute
Hogan was arrested earlier this year after police say she poisoned her husband’s wine and iced tea using ethylene glycol, a toxic chemical commonly found in antifreeze. Investigators allege the drinks were left in the refrigerator for him to consume while she was not home.
The husband was later hospitalized, prompting a criminal investigation. According to court documents, Hogan initially denied responsibility but later admitted to poisoning the beverages, leading to an attempted murder charge that remains pending.
DNA deception uncovered by surveillance
According to an arrest warrant released by Connecticut State Police, Hogan is now accused of perjury and tampering with evidence after allegedly falsifying a paternity test during a custody case involving her two children.
In June 2021, Hogan reportedly told a family court judge that her estranged husband was not the biological father of either child. While paternity of the daughter was confirmed in January 2021, the paternity of the son remained unresolved.
A court ordered a paternity test in March 2023. Hogan claimed she brought her son to a testing lab in April 2024, but investigators say that claim was false.
A private investigation firm, hired without Hogan’s knowledge, conducted surveillance and concluded that the child taken to the lab was actually Hogan’s nephew, not her son.
Key evidence cited by investigators
Investigators identified the boy through social media records, linking him to Hogan’s sister. Surveillance footage reportedly showed Hogan returning the child to her sister after the lab visit.
One particularly damning detail cited in the warrant states that the child was overheard calling Hogan’s sister “Mommy”, a moment investigators say was also lip-read on video recorded during surveillance.
The report further states that Hogan’s mother accompanied her to the testing facility but remained in the car. Police believe neither Hogan’s mother nor sister knew about the alleged deception at the time.
Family members deny knowledge
According to investigators, Hogan’s sister told police she learned about the alleged misuse of her children only after reading court documents.
“She became angry upon discovering that her children were used to falsify a DNA test,” the warrant states. The sister reportedly said she has had minimal contact with Hogan since learning of the allegations.
Police also noted that Hogan’s sister believed their mother had no knowledge of the plan. A lawyer representing Hogan’s mother confirmed to authorities that the mother was unaware of any intent to use the nephew for DNA testing.
A former boyfriend of Hogan’s, who previously lived with her and the children, also identified the boy seen at the lab as Hogan’s nephew, not her son.
Judge rejects testimony
After reviewing the surveillance footage during a December 2024 hearing, a judge concluded that Hogan “was not presenting truthful testimony” regarding the DNA test, according to the arrest warrant.
That finding ultimately led to the new criminal charges.
New charges and court dates
Hogan has now been charged with perjury and tampering with evidence. Police say she turned herself in and posted $50,000 bond. She is scheduled to appear in court on December 23 for those charges.
Her attempted murder case related to the alleged antifreeze poisoning is still active. Court records show her next hearing in that case is scheduled for January 27, 2026.
Ongoing legal fallout
The case highlights the lengths investigators say Hogan allegedly went to influence custody proceedings, with prosecutors now pointing to a pattern of deception spanning multiple years.
As both cases move forward, Hogan remains free on bond while awaiting multiple court appearances.
