Julia Gutierrez, 54, pleaded guilty April 27 to first degree murder in the death of her husband by giving him a smoothie drink containing a fatal overdose of a sedative.
She had given the smoothie to her husband, Eduardo Gutierrez, 53, when he came home for lunch sometimes between Jan. 26 and Jan. 28, 2016.
Police did a wellness check at the home, eventually breaking in on Jan. 28 when no one answered the door.
Police found Eduardo Gutierrez dead on the first floor and Julia Gutierrez in a fetal position in an upstairs bathroom, semi-conscious from a failed suicide attempt using the same sedative she used to kill her husband.
Kane County Circuit Judge D.J. Tegeler amended her plea to guilty, but mentally ill, noting it was a designation she had failed to say. The Kane County Diagnostic Center diagnosed Julia Gutierrez with somatic symptom disorder and a secondary diagnosis of depression.
The plea agreement meant she waived her right to a trial and prosecutors would dismiss a second murder charge.
