The lawyer for a Massachusetts man charged with killing his mother plans to use an insanity defense.
The Telegram & Gazette reports that a 2018 psychological evaluation authorized by a judge found 28-year-old John Madulka competent to stand trial.
But in a motion filed Wednesday, the defense says an earlier evaluation conducted while the case was pending in district court determined that the Worcester man is mentally ill.
A psychologist said Madulka had not taken his medication for months triggering "acute symptoms" of schizophrenia.
Prosecutors say Madulka beat and stabbed 56-year-old Ellen Madulka to death in December 2017.
He has pleaded not guilty.
Madulka's attorney, Michael Hussey, and prosecutors plan to seek testimony from mental health experts.
