Michael Brea did not speak as he was arraigned Friday from the hospital prison ward where he has been under evaluation since his Nov. 23 arrest. He did not enter a plea. His lawyer didn't immediately return a call seeking comment.
Prosecutors say he was also charged with criminal possession of a weapon for the 3-foot sword he had at his Brooklyn apartment when he was arrested. Police say he snapped and slashed his mother, Yanick, to death.
Brea had small roles in ABC's now-canceled show "Ugly Betty" and the movie "Step Up 3D." He told the Daily News of New York that he had been hearing voices before the attack.
