Illinois Woman Pleads Guilty but Mentally Ill in 2020 Double Homicide

An Illinois woman has admitted her guilt but with the acknowledgment of her mental illness in the tragic 2020 double homicide of her then-boyfriend's parents.

Arin M. Fox, aged 42, recently pled guilty in McHenry County to one murder charge. In exchange for this plea, prosecutors dropped three additional murder charges and other allegations that included possession of a stolen vehicle, aggravated battery, and domestic battery, according to The Daily Herald in Arlington Heights.

The incident revolves around the unfortunate deaths of Noreen S. Gilard, aged 69, and Leonard J. Gilard, aged 73, that occurred in November 2020 at their Algonquin residence. The victims were the parents of Arin Fox's boyfriend at that time. Following the crime, she then took their car and drove to Douglas County, Colorado, where authorities apprehended her.

Fox's plea deal comes with a stipulation that acknowledges her mental health condition. All parties involved, including Fox herself, concur that she had been previously diagnosed with bipolar disorder, schizoaffective disorder, and schizophrenia by three different doctors. A clinical psychologist's evaluation stated that Fox "meets the criteria for a plea of guilty but mentally ill."

In the legal context, "guilty but mentally ill" signifies that a defendant has a mental illness but still comprehends the distinction between right and wrong.

Arin M. Fox is currently in custody at the McHenry County jail. She now faces a potential sentence of 40 to 60 years in prison, with her sentencing scheduled for December 6.

For her part, Fox's attorney, assistant McHenry County public defender Kyle Kunz, declined to comment on his client's plea.
