brothers killed Leonard and Head during the hold-up. Some modern researchers state that Brocius and friend Johnny Ringo rode to New Mexico to avenge their friends' deaths and killed both Haslett brothers. However, no witnesses to this crime were found nor to Curly Bill's involvement in the Hasletts' death. Four months after Brocius was shot, on October 6, 1881, George Parsons rode through the McLaury brothers' ranch in Sulphur Springs Valley as part of an Indian scouting party, and noted that Brocius had not yet fully recovered from his wound, but was well enough to ride. For this reason, many historians doubt that Brocius took part in killing William and Isaac Haslett. Participation in Skeleton Canyon Massacre In July, some reports say that Brocius ambushed a Mexican trail herd in the Skeleton Canyon Massacre. Six vaqueros were killed and the remainder captured, then possibly tortured and murdered. Curly Bill reportedly sold the stolen Mexican beef to Newman Haynes Clanton the next month. When Old Man Clanton was herding the beef on the trail to Tombstone, he and four others were ambushed in the Guadalupe Canyon Massacre and murdered by Mexicans. No reports were verified of Curly Bill's involvement in these episodes, nor was he charged with any crimes related to these events. Brocius was still recovering from being shot in the face by Wallace only six weeks earlier. Some modern researchers doubt that he was well enough to take part in these events. Assassination of Morgan Earp Following the Gunfight at the O.K. Corral on October 26, 1881, Brocius robbed the Tombstone–Bisbee stagecoach on January 6, 1882, and the Tombstone-Benson stage the next day. Deputy U.S. Marshal Wyatt Earp gathered a posse and rode after the men, but was unable to find them in the Chiricahua Mountains. Brocius returned to Tombstone on March 17. He was named by Pete Spence's wife Marietta Duarte as a participant in the assassination of Morgan Earp. Justice of the Peace Wells Spicer disallowed her testimony because it was hearsay and because she could not testify against her husband. Lacking evidence, the prosecution dropped all charges against the Cowboys. Deputy U.S. Marshal Wyatt Earp killed outlaw Cowboy Frank Stilwell in Tucson on March 20, 1882, while guarding his brother Virgil en route to California. Death at Iron Springs On March 24, 1882, the Earp party was expecting to meet Charlie Smith at Iron Springs (later
