Man Who Impregnated Disabled Nursing Home Resident Sentenced
The Batavia man was sentenced after he pleaded guilty to criminal sexual assault of a victim at Marklund Home in unincorporated Geneva.

GENEVA, IL — A man who impregnated and sexually assaulted a woman with an intellectual disability at Marklund Home was sentenced to 25 years in prison, officials said.
Isaiah Fields, 24, received his sentencing from Judge John Barsanti two months after he pleaded guilty on Jan. 14 to aggravated criminal sexual assault.
Fields sexually assaulted the victim, who he knew had a "severe or profound intellectual disability and was unable to give consent," between Aug. 1, 2023, and Sept. 5, 2023, Assistant State's Attorney Matthew Rodgers said in court. The woman was a 20-year resident at the unincorporated Geneva nursing home for people with intellectual and developmental disabilities.

In April 2024, it was discovered that the victim was pregnant and nearly full term. She later gave birth, according to prosecutors. During the Kane County Sheriff's Office investigation, a team secured multiple buccal swab DNA tests from current and previous male employees, and after Fields' DNA test came back positive, the sheriff secured a sealed order for his arrest.
Fields, whose address is listed in the 1800 block of Wagner Road in Batavia, will be required to register for life as a sexual offender. He is required to serve 85 percent of his sentence, for which he is credited for the 308 days spent in the Kane County jail.
"Today's sentencing holds Isaiah Fields accountable for his heinous actions and the profound harm he caused to a vulnerable individual who was unable to protect themselves," State's Attorney Jamie Mosser said in a statement. "The bravery of the victim's caregivers, the diligent work of law enforcement, and the efforts of my office ensured that justice was served. This sentence reflects the gravity of his crime, and we remain committed to safeguarding the most vulnerable members of our community from exploitation and harm."
