Morgan Seth Earp (April 24, 1851 – March 18, 1882) was an American sheriff and lawman. He served as Tombstone, Arizona's Special Policeman when he helped his brothers Virgil and Wyatt, as well as Doc Holliday, confront the outlaw Cochise County Cowboys in the gunfight at the O.K. Corral on October 26, 1881. All three Earp brothers had been the target of repeated death threats made by the Cowboys who were upset by the Earps' interference in their illegal activities. The lawmen killed Cowboys Tom and Frank McLaury and Billy Clanton. All four lawmen were charged with murder by Billy's older brother, Ike Clanton, who had run from the gunfight. During a month-long preliminary hearing, Judge Wells Spicer exonerated the men, concluding they had been performing their duty. Wikipedia
