(1) inform all on-duty law enforcement officers of the existence of the missing child report;
(2) communicate the report to all other law enforcement authorities having jurisdiction in the county;
(3) enter the missing child report into the national crime information center computer system; and
(4) if the missing child is enrolled in a Montana public school district, request the child's directory photograph from the superintendent of public instruction pursuant to 20-7-1317. If a directory photograph is available, it must be included with the missing child report.
