A drug cartel is believed to behind the murder of 72 illegal immigrants found on a ranch in Texas near the Mexican border. The lone survivor who stumbled wounded to a checkpoint on the highway told his story of woe to marines manning the post. Police later found the bodies of 58 men and 14 women. The man claims he was kidnapped by an armed gang who demanded extortion money. Authorities suspect the gang was the notorious Zetas drug cartel who control the area. Hmm, since when have a drug cartel controlled parts of Texas ?
