Adolph Coors III

[5] On September 11, 1960, a hiker by the name of Edward Lee Greene Jr. stumbled upon a pair of discarded trousers in the Rocky Mountains, and found in the pocket a penknife bearing the initials 'ACIII'.

[8][9] A witness turned up that revealed he had seen a yellow 1951 Mercury with the letters "AT" and numerals "62" somewhere in the license plate combination on the bridge around the time of Coors' disappearance.

[10] Investigators traced the car back to a Colorado resident named Walter Osborne, who suspiciously moved out of his Denver apartment the day after the kidnapping.

[4] Due to international obsession with the case, including a picture of Corbett in an issue of Reader's Digest, he was recognized by two neighbors in Vancouver, BC, and was arrested.

Investigators were able to trace the car's path by noting the rare pink feldspar and granite minerals found in the area Coors' body was discovered.

The 2017 true crime book The Death of an Heir: Adolph Coors III and the Murder That Rocked an American Brewing Dynasty by Phillip Jett details the kidnapping.
