In 1854 he was sent by the War Department to Utah to investigate the recent massacre of John W. Gunnison and his survey party. In particular he was to determine the truth of rumors that Mormons had colluded with the Indians in the ambush. Steptoe charged eight Paiute Indians for the attack and three were convicted of manslaughter. He did not uncover evidence of Mormon involvement.[5]
Late in 1854, President Franklin Pierce offered Steptoe the governorship of the Utah Territory to replace Brigham Young. Steptoe did not receive the actual letter from Pierce until March 1855. By that time he had already decided to turn down the offer.[4] Instead, he was promoted to Major of the newly formed 9th Infantry Regiment.
Steptoe was sent on sick leave after the battle, during which he was promoted to lieutenant colonel, and resigned due to ill health in November 1861. He died four years later in his home state of Virginia. He is buried in Lynchburg, Virginia, where his tombstone is marked: "Edward J. Steptoe, Lieut. Col., Army of the United States."
