According to the literature of the OTS, the central authority was the Synarchy of the Temple, whose membership was secret. Its top 33 members were known as the Elder Brothers of the Rosy Cross (an alternative name for the Rosicrucians), and were headquartered in Zürich, Switzerland. The Council of the Order formed Lodges that were run by a Regional Commander and three Elders. Progression in the Order was by levels and grades, with three grades per level — the levels being The Brothers of Parvis, The Knights of the Alliance and the Brothers of the Ancient Times, in ascending order. There were many organizations associated with the OTS, including the International Archedia Sciences and Tradition, Archedia Clubs, Menta Clubs, Agata Clubs and Atlanta Clubs, all of which offered the teachings of Luc Jouret both to the general public and privately to OTS members. The Lodges had altars, rituals and costumes. Members were initiated at each stage of advancement in ceremonies which included expensive purchases, jewellery, costumes, regalia, and the payment of initiation fees. During ceremonies, members wore Crusader-type robes and were to hold in awe a sword, which Di Mambro said was an authentic Templar artifact, given to him a thousand years ago in a previous life.
In October 1994, Tony Dutoit’s infant son (Emmanuel Dutoit), aged three months, was killed at the group’s centre in Morin-Heights, Quebec. The baby had been stabbed repeatedly with a wooden stake. It is believed that Di Mambro ordered the murder, because he identified the baby as the Antichrist described in the Bible. He believed that the Antichrist was born into the order to prevent Di Mambro from succeeding in his spiritual aim.
A few days later, Di Mambro and twelve followers performed a ritual Last Supper. A few days after that, apparent mass suicides and murders were conducted at Cheiry and Salvan, two villages in Western Switzerland, and at Morin Heights—15 inner circle members committed suicide with poison, 30 were killed by bullets or smothering, and 8 others were killed by other causes. In Switzerland, many of the victims were found in a secret underground chapel lined with mirrors and other items of Templar symbolism. The bodies were dressed in the order’s ceremonial robes and were in a circle, feet together, heads outward, most with plastic bags tied over their heads; they had each been shot in the head. The plastic bags may have been a symbol of the ecological disaster that would befall the human race after the OTS members moved on to Sirius; it’s also possible that these bags were used as part of the OTS rituals, and that members would have voluntarily worn them without being placed under duress. There was also evidence that many of the victims in Switzerland were drugged before they were shot. Other victims were found in three ski chalets; several dead children were lying together. The tragedy was discovered when officers rushed to the sites to fight the fires that had been ignited by remote-control devices. Farewell letters left by the believers stated that they believed they were leaving to escape the “hypocrisies and oppression of this world.”
A mayor, a journalist, a civil servant, and a sales manager were found among the dead in Switzerland. Records seized by the Quebec police showed that some members had personally donated over C$1 million to Di Mambro. Another attempted mass suicide of the remaining members was thwarted in the late 1990s. All the suicide/murders and attempts occurred around the dates of the equinoxes and solstices in some relation to the beliefs of the group.
Another mass-death incident related to the OTS took place during the night between the 15 and 16 December 1995. On 23 December 1995, 16 bodies were discovered in a star-formation in the Vercors mountains of France. It was found later that two of them shot the others and then committed suicide by firearm and immolation. One of the dead included Olympian Edith Bonlieu, who had competed in the women’s downhill at the 1956 Winter Olympics.
On the morning of 23 March 1997, five members of the OTS took their own lives in Saint-Casimir, Quebec. A small house erupted in flames, leaving behind five charred bodies for the police to pull from the rubble. Three teenagers, aged 13, 14 and 16, the children of one of the couples that died in the fire, were discovered in a shed behind the house, alive but heavily drugged.
