The managing officer of an institution under the control of the department of developmental disabilities shall immediately report the removal, death, absence without leave, discharge, or trial visit of any resident, or return of an absent without leave or visiting resident to the department, the probate judge of the county from which such resident was institutionalized, and the probate judge of the county of the residence of such resident. In case of death, the managing officer shall also notify one or more of the nearest relatives of the deceased resident, if known to the managing officer, by letter, telegram, or telephone. If the place of residence of such relative is unknown to the managing officer, immediately upon receiving notification, the probate judge shall in the speediest manner possible notify such relatives, if known to the probate judge.
The managing officer of the institution shall, upon the request of the probate judge of the county from which such resident was institutionalized or the probate judge of the county of the residence of such resident, make a report to such judge of the condition of any resident under the care, treatment, custody, or control of such managing officer.
