Tragedy at Tunnel 13. The d'Autremont brothers and "The Edison of Crime Detection".
Train robbery was frequent in the United States from the late 1800s through the 1920s. On October 11, 1923, the southbound Southern Pacific Express was halted by three men at Tunnel 13 in southern Oregon just north of the California line. The railway mail car carrying +40,000 was then blown apart by an explosive charge, killing the clerk and rendering the money unobtainable. The men shot three other train crew members before escaping into the mountains. The investigation was headed by Chief Agent Dan O'Connell, who soon asked that California criminalist, Edward Heinrich, examine soiled overalls found nearby. Using primarily botanical evidence, Heinrich identified them as those of a woodsman, leading to the identification of three Oregon d'Autremont brothers as suspects. After an intensive manhunt, one was captured 3 years later in the Philippines and was tried and found guilty. The twins, captured in Ohio, then pleaded guilty. This crime, typical of those in which unforeseen events lead the perpetrators to panic and to murder, helped to establish criminology and particularly botanical studies as valid scientific disciplines. Its investigation and solution also remain models of scientific crime detection.
