OAKLAND, Calif. (AP) — A judge has suspended criminal proceedings against a suspect accused of killing seven people at a small California Christian college after the suspect's lawyer questioned his mental competency to stand trial.

Alameda County Superior Court Judge Carrie Panetta on Monday ordered that two psychiatrists examine 43-year-old One Goh and report their findings next month.

Assistant public defender David Klaus told Panetta during a brief hearing that Goh refuses to speak to him and that a mental evaluation is necessary to determine if Goh is fit to stand trial.

Goh is charged with seven counts of murder and three counts of attempted murder in the April 2 attack at Oikos University in Oakland.

Authorities said Goh, a former student, planned the shootings after becoming angry over a tuition dispute with school officials.
