Mexico's Christian Meth Cartel

Mexico's newest drug cartel, and certainly the most bizarre, is La Familia Michoacana, a violent but Christian fundamentalist narco-gang based in the torrid Tierra Caliente region of western Michoacan state. The group is infamous for methamphetamine smuggling, lopping off enemies' heads and limbs, and massacring police and soldiers.

On June 14, a band of Familia gunmen ambushed a federal police convoy in Michoacan, killing 12.

Yet La Familia's leader, Nazario Moreno — aka El Mas Loco, or The Craziest One — has written his own bible, and his 1,500 minions hold prayer meetings before doing their grisly work.

La Familia now exports about 100 tons of meth to the U.S. each year, with a street value of as much as $10 billion.
