Generally revise sexual abuse reporting laws

This bill revises Montana's sexual abuse and exploitation reporting laws to improve how county attorneys handle cases involving children aged 12 or older. It requires county attorneys to collect and retain all investigative materials for 25 years, request assistance from the Department of Public Health and Human Services when perpetrators are unidentified, and certify receipt of reports to initial reporters. County attorneys must also submit detailed annual reports to the attorney general tracking case outcomes, including charges filed, prosecutions declined, and convictions obtained. The attorney general will then compile this data into annual reports for the legislature, providing aggregated information on case status and outcomes while maintaining confidentiality for sensitive criminal justice information.
