Authorities are trying to figure out how many were killed at a Jalisco ranch that apparently was used as a cartel training camp. Some call it the ‘Mexican Auschwitz.’

The remote ranch outside Mexico's second-largest city, Jalisco, was allegedly being used as a training base for cartel recruits.

A grisly discovery of charred bones, shoes and clothing at a suspected drug cartel training ground has prompted demands for answers and justice from relatives of the more than 100,000 people missing in Mexico.
