RYMUR (The Leo Ryan Murder/Jonestown Investigation) On November 18, 1978, while investigating human rights abuses by a large cult led by James Warren “Jim” Jones (1931-1978), Congressman Leo Ryan (1925-1978) and several companions were murdered by Jones’ followers. Ryan had traveled to “Jonestown,” the cult’s compound in the South American country of Guyana, at the behest of his constituents, some of whom had family members in the cult. Following Ryan’s murder, Jones ordered his followers to commit mass suicide; more than 900 bodies were later found, most having died by taking poison. The FBI, charged with investigating violence against public officials, opened a probe into the murder of Ryan (hence the case name RYMUR) and provided other support and investigative assistance in relation to the mass casualties. This release consists of material released previously and ranges from 1978 To 1979.
