Who is David Salgado?
Héctor David Delgado Santiago (23 December 1975 – 15 January 2013), commonly referred to by his alias El Metro 4, was a suspected Mexican drug lord and high-ranking leader of the Gulf Cartel, a criminal group based in Tamaulipas. Born and raised in Matamoros, Tamaulipas, El Metro 4 initiated his criminal career by working with Los Metros, an enforcer gang of the Gulf Cartel. After several years, his position in the cartel grew, and he later became the regional leader in Reynosa, Tamaulipas and the right-hand man of the drug lord Mario Ramírez Treviño. Although no official reports have been released, several media outlets alleged that El Metro 4 was found dead in Reynosa on 15 January 2013. The motives behind his murder are still unknown, but the two prevailing theories suggest that he was killed by the rival gang Los Zetas or betrayed by members of his own cartel.
