The court may order an offender whose sentence includes community placement or community supervision to undergo a mental status evaluation and to participate in available outpatient mental health treatment, if the court finds that reasonable grounds exist to believe that the offender is a mentally ill person as defined in RCW
71.24.025, and that this condition is likely to have influenced the offense. An order requiring mental status evaluation or treatment ((
must))
may be based on a presentence report and, if applicable, mental status evaluations that have been filed with the court to determine the offender's competency or eligibility for a defense of insanity. The court may order additional evaluations at a later date if deemed appropriate.
