When Morgan Earp was murdered in a Tombstone pool hall on March 18,1882, a coroner's jury determined that the murderers were Frank Stilwell, Indian Charlie, Pete Spencer, Joe Doe Freis and an unidentified Indian.
Wyatt, infuriated at the killing of his younger brother Morgan and the earlier crippling of his older brother Virgil, rode a bloody trail of revenge. Wyatt and his posse killed Stilwell in Tucson on March 20, 1882.
Two days later they rode to Pete Spencer's woodcutter camp at South Pass in the Dragoon Mountains. Spencer was not at the camp, but Florentino Cruz was. Wyatt and his posse shot him full of holes and left him there. Taken into Tombstone, he was buried in Boothill.
