What are the factors used by a federal district court to determine whether a child has been found to have committed a sexual assault?

In departing downward, the district court relied on a combination of its finding of aberrant behavior and extraordinary family circumstances. A "unique combination of factors" may constitute an aggravating or mitigating circumstance justifying a downward departure. United States v. Anders, 956 F.2d 907, 911 (9th Cir.1992); United States v. Cook, 938 F.2d 149, 153 (9th Cir.1991). However, the factual findings relating to permissible factors must be based on "the necessary quantum of evidence to survive the clearly erroneous standard of review." Anders, 956 F.2d at 914.
