A caregiver who sexually assaulted and impregnated a severely disabled woman living at the Illinois facility where he worked has been sentenced to 25 years in prison, as reported by prosecutors.

Isaiah Fields, 23, was found guilty of taking advantage of a 43-year-old woman with Rett Syndrome, a condition that causes her to have the cognitive abilities of an infant, at the Marklund Hyde Center between Aug. 1, 2023, and Sept. 5, 2023, according to the Daily Herald.

During his sentencing in Kane County court, the offender was quoted as saying, “There is no reason or set of experiences that could justify hurting anyone in any way,” as he attempted to apologize to the victim’s family on Friday.

The woman, who has lived at the center that serves disabled people since she was in her early 20s, is unable to read, write, talk or even stand, as well as consent to sex, prosecutors noted, according to the newspaper.

The stomach-churning crime was only uncovered when the woman was checked out at a hospital for liver and gallbladder issues, and doctors discovered she was at least 31 weeks pregnant, the newspaper reported.

A baby boy was born the next day because the woman was suffering from preeclampsia. The newborn died after spending 11 weeks in a neonatal intensive care unit.

“[The baby] didn’t live long in this world,” prosecutor Matthew Rodgers said during the sentencing, the Daily Herald reported. “But simply by coming into this world, he did justice for his mother.”

The child’s DNA was matched up with Fields, leading to his charges, the Kane County State’s Attorney’s Office said.

He pleaded guilty in January to aggravated criminal sexual assault.

On top of the jail term, Fields will be designated as a sex offender when he’s released. 

“Isaiah Fields preyed on this vulnerable victim because of her physical and intellectual disability,” Rodgers said in a statement.

“While no sentence can undo the harm caused, today’s outcome ensures that the defendant will be held accountable for his despicable act. It also represents justice for the victim, her family and the Marklund community.”
