Carleton interviewed a few local Mormon settlers and Paiute Native American chiefs and concluded that there was Mormon involvement in the massacre. He issued a report in May 1859, addressed to the U.S. Assistant Adjutant-General, setting forth his findings. Jacob Forney, Superintendent of Indian Affairs for Utah, also conducted an investigation that included visiting the region in the summer of 1859. Forney retrieved many of the surviving children of massacre victims who had been housed with Mormon families and gathered them up for transportation to their relatives in Arkansas. Forney concluded that the Paiutes did not act alone and the massacre would not have occurred without the white settlers, and Carleton report to the U.S. Congress called the mass killings a "heinous crime", blaming both local and senior church leaders for the massacre.
