SEATTLE — United Nations gang leader Clay Roueche should spend at least 30 years behind bars after his surprise guilty plea here Tuesday for conspiracy to smuggle cocaine, marijuana and illicit drug profits, U.S. Attorney Jeffrey Sullivan said. Sullivan said outside court that Roueche's leadership of the violent UN gang and the sophistication of the international drug conspiracy will all be factors used to argue for a longer sentence — up to life — for the 33-year-old Canadian. And he stressed that the plea agreement reached with Roueche did not include "any kind of break with respect to sentencing.".
