Edward O. Heinrich
Edward Oscar Heinrich (1881-1953) was a forensic criminologist and lecturer at the University of California, Berkeley.
The Last Great Train Robbery
On October 11, 1923, the three DeAutremont brothers attempted, but failed to rob the mail car of a Southern Pacific train. Instead, they ended up blowing it up completely and murdering four people. The case was solved and the suspects apprehended through the pioneering work of Heinrich.[1]
The Case of Martin Colwell
On Dec. 19, 1925, John McCarty was gunned down by a disgruntled employee, Martin Colwell. The case was proved using a new forensic analysis developed by Heinrich utilizing "bullet fingerprints", microscopic evidence that the bullet which killed McCarty could only have been fired from Colwell's .38 revolver.[2]
