"Death, drugs and the occult meet in grisly inquiry at the Mexican border" in this true crime account of a mass murder by a serial killing cult leader (The New York Times).

When Mark Kilroy vanished while on spring break in Matamoros, Mexico, the search for the missing pre-med student led to a gruesome discovery on a lonely stretch of land called Rancho Santa Elena: a mass grave containing Mark's mutilated corpse along with the remains of thirteen other people. The investigation uncovered how the victims were brutally killed at the hands of drug trafficker and cult leader Adolpho Constanzo, known by his followers as El Padrino, or The Godfather. Constanzo was a serial killer who, along with his followers, tortured and cannibalized innocent people in the barbaric religious ritual of human sacrifice.

Written by critically acclaimed journalist Jim Schutze, Cauldron of Blood is a must-read for true-crime fans.
