The Mexican authorities, initially cooperative, began treating Marcus with polite but distant patience. The case had been officially closed in 1997, three years after the disappearance. There were no new leads, witnesses, or evidence. The desert had maintained its absolute silence, and the authorities had more recent and solvable crimes to investigate. During that time, life went on for everyone except Marcus. He became a familiar figure in police stations on both sides of the border, always carrying the same worn leather folder containing faded photographs of Ethan and Alice.
His determination was admirable, but it was also beginning to worry those who knew him. The desert, however, guarded its secrets with infinite patience, under the scorching sun and freezing nights. Something was waiting for the right moment to be revealed. Nature has its own way of revealing the truth, and sometimes that happens when least expected, through the most unlikely people. The morning of October 23, 2007, dawned clear and dry in the Chihuahuan Desert.
The sun was in the perfect position for the photographs he planned for his next exposure. It was while circling a rocky outcrop that Klaus stumbled upon a scene that would change his life forever. In the center of a small valley, a zaguaro cactus, approximately 4 meters tall, presented a grotesque and unsettling form. Among its thorns, wrapped in cables that had withstood the test of time and the elements, lay the remains of a human being. The skeleton was impaled on the cactus, suggesting a slow and agonizing death.
