A Darien man was sentenced Tuesday to five years in prison for stabbing his 81-year-old mother in the face with a meat carving fork.
Marcos Osoteo, 54, pleaded guilty but mentally ill to aggravated battery with a deadly weapon.
The attack happened in March 2012 during an argument at the defendant's home on the 8500 block of Ailsworth Drive.
Prosecutors said Osoteo retrieved a 10-inch, two-pronged meat carving fork from the kitchen and repeatedly stabbed his elderly mother.
Afterward, he called 911 and summoned police, Assistant State's Attorney Mike Fisher said.
The victim was treated for lacerations and fractures to her face and skull, according to court records. She also suffered injuries to her throat and hand.
Osoteo reached a plea agreement with prosecutors after a psychiatric evaluation showed he was impaired by symptoms of schizophrenia at the time of the offense but still understood the criminality of his actions.
By law, Osoteo must serve at least 2½ years. With credit for time spent in jail since his arrest, he is expected to be paroled in less than a year, said his attorney, Senior Assistant Public Defender Mark Lyon.
The sentence was imposed by DuPage County Judge Kathryn Creswell.
