Edward O. Heinrich, private detective
by Michael Thomas Barry
On October 11, 1923, three men blow up the mail car of a Southern Pacific train carrying passengers through southern Oregon in a botched robbery attempt. Just as the train entered a tunnel, two armed men jumped the engineer. A third man appeared with a bomb that the thieves intended to use to open the mail car. However, the explosives were too powerful and the entire mail car was blown to bits, killing the clerk inside. In the ensuing chaos, the train robbers shot the train's engineer, fireman, and brakeman, and then fled. They left behind the detonator and some clothes, but bloodhounds were unable to track them.
