U.S. v. Gries

Dist. Ct. erred in imposing concurrent sentences on charges of conspiracy to distribute child pornography and conspiracy to sexually exploit child, where Dist. Ct. also imposed sentence on charge of engaging in child-exploitation enterprise. Instant conspiracy charges were predicate offenses for instant enterprise charge, and thus imposing any sentences for conspiracy offenses would violate Double Jeopardy Clause, since sentences on conspiracy charges constitute separate sentences for same enterprise offense.
