OAKLAND, Calif. (AP) -- A man accused of killing seven people at a small California Christian college has been deemed mentally unfit for trial.

A judge issued the ruling Monday and ordered defendant One Goh to return to court Jan. 28.

Goh is charged with seven counts of murder and three counts of attempted murder in the April 2 attack at Oikos University in Oakland. He has pleaded not guilty.

His attorney says a psychiatrist determined that Goh suffers from paranoid schizophrenia that dates back several years.

Alameda County Assistant Public Defender David Klaus has said the condition causes Goh to distrust people, including those trying to help him.
