"They went looking for Stilwell..."
Wyatt Earp walks, at center, with Doc Holliday and Warren Earp, down the Tucson train tracks. They had seen Frank Stilwell, one of the men thought to have murdered Wyatt's brother, Morgan, only 2 nights before.
They found Stilwell that night. The next morning men working on the train lines found Stilwell, too, his body perforated by numerous shotgun and pistol shots. Stilwell was the first of 3 or 4 men who Earp and his posse murdered when they stepped outside the law to pursue the men they thought had killed Morgan.
