A Deerfield man has been found guilty but mentally ill in the slaying of his girlfriend's mother.
A judge delivered the verdict to Daniel Baker, 24, in court Monday morning, the Chicago Tribune reported.
Baker was charged with beating Marina Aksman to death with a baseball bat after smashing an SUV into her Vernon Hills home in 2010.
The defendant gave up his right to a jury trial.
He will likely receive a long prison sentence and receive mental health treatment while in jail, the newspaper reported.
Police arrested Baker a week later after Aksman's death after finding him speeding in the victim's car on a Montana road. Aksman's daughter, Kristina Aksman, was a passenger in the car but ultimately was not charged.
Prosecutors contend Baker killed Aksman because she was trying to break up the couple.
