I would heartily recommend membership in a competent SAR group. There may some variation with respect to use of underage volunteers. In Arizona, our teenagers responded on their own, with prior signed parental approval to participate in operations.

We had operations where boys and girls started out, and returned as men and women. Incredibly good for everyone, including the victim. My experience hs been that teens respond better if you pull them out of their peer group, and put them in a real world situation where they are expected to show maturity. They almost always do.
