The Locker Room - Pedro's Drug Problem

Pedro is in trouble. He got mixed up with the wrong crowd and now he is being held by a drug cartel accused of selling drugs on their turf. But it is all a mistake - Pedro is a good guy and he has never sold drugs in his life.

Can you find the evidence before the cartel takes decisive action?
