A 19-year-old woman accused of stabbing her mother 151 times has pleaded not guilty by reason of insanity.
According to our sister station KCNC, who was in the courtroom Thursday as Isabella Guzman entered her plea, Guzman will now bed admitted to the state mental hospital.
On the night of August 28, 2013, police say they responded to a "family disturbance" on South Lima Street just after 10 p.m. When police arrived, they say they found a woman in the home's upstairs bathroom in "grave condition." She died a short time later.
Arrest papers at the time said she had been stabbed 75 times. The adjusted number was stated in court Thursday.
Guzman reportedly left the home sometime before police arrived that night. She was arrested a day later.
Arrest papers said the Guzman's behavior toward her mother changed after her parents got divorced.
The victim also allegedly got a threatening email from Guzman containing the words "you will pay" the day before the murder. The mother called police.
KCNC says that a doctor testified in court Thursday that Guzman was schizophrenic and had been suffering from delusions for years. The doctor said he did not believe that Guzman thought she was stabbing her mother, but instead a woman named Cecilia who needed to be killed in order to save the world.
The prosecution said they agreed with the doctor's assessment of Guzman's mental instability.
"We punish people who make decisions to do wrong when they knew better and they could have done something differently. And in this particular case I am convinced, based on the evidence that I’ve seen and the information that’s been presented in court, that this woman did not know right from wrong and she could not have acted differently than she did, given the significant schizophrenia and paranoid delusions, audible, visual hallucinations that she was going through," 18th Judicial District Attorney George Brauchler said in court.
Guzman will remain in the mental hospital until she's no longer deemed a threat to herself or others. She could potentially be there for the rest of her life.
