Born and raised in Austria, Edward Bolcke had spent his youth scouring the Alps for gold and rare minerals. It was his means of escape after his mother had run away with an American GI, leaving him in the care of an alcoholic father prone to violence. The young Bolcke’s mountain hikes fostered a love of geology, which led to a degree in mineral resources engineering from Austria’s University of Leoben.

He took a job at a copper mine in Poland, and before long was hopscotching the globe, working tin mines in Malaysia, gold mines in Indonesia, and silver mines in South America. With an uncanny ability to locate the richest ore concentrations, he boosted recovery rates and profits everywhere he went.

But in Colombia, life threw him a twisted bone. Bolcke took an ownership interest in a small silver operation in the Tolima district. His astute analysis of the claim revealed a more valuable deposit of platinum alongside his property. He secured the rights and struck a major deposit, making him wealthy in a matter of months. While celebrating his good fortune in Bogotá, he met the vivacious daughter of a Brazilian industrialist and soon married.

He led a storybook life for several years, expanding his riches from the mine—until one day he returned to his home in Bogotá to find his wife in bed with an American consulate worker. With a fury he never knew he possessed, he shattered the man’s skull with a rock hammer. His wife came next, her throat crushed by his thick, burly hands.

A Colombian jury, well greased by his defense attorneys, acquitted him on the grounds of temporary insanity. He walked away a free man.

He was free physically, but not psychologically. The event reopened childhood scars of abandonment, while slashing new wounds. A bloodthirsty anger flooded his soul—and refused to recede. He sought revenge, turning to the easiest victims he could find: helpless young women. Cruising the slums of Bogotá at night, he would hire young prostitutes, then beat them unmercifully to vent his rage. Nearly gunned down one night by a watchful pimp, he finally abandoned that outlet for his rage and left Colombia, selling his remaining interest in the mine.
