 He also denied allegations of being a senior leader in the Sinaloa cartel or being active in the drug trade.Former DEA agent Mike Vigil, who previously led the DEA international operations and was highly active in investigating Mexican drug operations, described Caro Quintero as "a shell" of his former self and stated that it was "ludicrous" to look into allegations that he might have leadership in the Sinaloa Cartel.Vigil even stated "Right now, we don’t have any information that he is actually working with anybody."
