The term "Chain Murders" was first used to describe the murder of six people in late 1998. The first two killed were 70-year-old Dariush Forouhar (secretary general of the opposition party, the "Nation of Iran Party"), and his wife Parvaneh Eskandari, whose mutilated bodies were found in their south Tehran home on 22 November 1998. Forouhar received 11 knife wounds and Eskandari 24. Their home, which was later ransacked, was thought to be under 24-hour surveillance by the Ministry of Intelligence and National Security of Iran, thus casting suspicion on that ministry for at least complicity in the murder.
