Washington state officials say another patient has gone missing from a psychiatric hospital being scrutinized after a man accused of killing a woman escaped and remains on the loose.

Officials said Friday that the patient left the facility Wednesday with an escorted group but didn't return. The patient, who wasn't identified, was committed to Western State Hospital after being deemed unfit to face trial on residential burglary charges and violation of a no-contact order.

The patient's whereabouts aren't known, and police have been notified. The patient was under less restrictive conditions than the two men who escaped out a window later the same day.

The revelation comes after Anthony Garver fled a lower-security ward with another patient who was caught Thursday. Garver, who was charged with torturing a woman to death but found too mentally ill for trial, is still at large.
