Di Mambro wrote four letters, known as ''The Testament'', which contained messages of the order's beliefs.{{sfn|Clusel|Palmer|2020|pp=218, 231}}{{sfn|Palmer|1996|p=303}} In these letters, the OTS termed the acts a "transit", which they described as "in no way a suicide in the human sense of the term".{{sfn|Hall|Schuyler|2000|p=117}} They declared that, upon death, they would acquire "solar bodies" on the star [[Sirius]].{{sfn|Wessinger|2000|p=219}}{{sfn|Palmer|1996|p=303}} The letters maintain a persecuted rhetoric.{{sfn|Hall|Schuyler|2000|p=144}} In one letter, they harshly criticize the allegations the OTS had received in several countries (Australia, Switzerland, Martinique, Canada, and France) as "deceitful", but especially complain about their SQ and the Q-37 investigation. They blamed their wish to leave the earth on systematic government persecution.{{sfn|Hall|Schuyler|2000|p=144}}{{sfn|Clusel|Palmer|2020|p=231}} On 30 September 1994, the Dutoits were lured to the chalet in Morin-Heights, having been invited to dinner by Bellaton.{{sfn|Bédat|Bouleau|Nicolas|1997|p=215}}{{sfn|Bédat|Bouleau|Nicolas|2000|p=212}}{{sfn|Clusel|Palmer|2020|p=229}} As ordered by Di Mambro, these murders were carried out in a ritualistic fashion.{{sfn|Clusel|Palmer|2020|p=230}} On 4 October the Genouds set incendiary timers to go off and, while wearing robes and medals, laid out on a bed, dying of [[asphyxiation]] from [[smoke inhalation]] when the fires began.{{sfn|Hall|Schuyler|2000|p=145}}{{sfn|Clusel|Palmer|2020|p=229}} According to telephone records, Di Mambro was informed of the success of the plan.{{sfn|Bédat|Bouleau|Nicolas|1997|p=217}}

On 30 September, Di Mambro had a meal with some followers near [[Montreux]] in Switzerland; according to an attendee (Vuarnet) Di Mambro had asked him to meet them, including Jouret and Pilet.{{sfn|Bédat|Bouleau|Nicolas|1997|pp=217–218}}{{sfn|Bédat|Bouleau|Nicolas|2000|p=213}} During the night from 2 to 3 October 1994, 23 died in Cheiry.{{sfn|Clusel|Palmer|2020|p=230}}{{sfn|Bédat|Bouleau|Nicolas|2000|p=214}} The ones who had killed the others in Cheiry were Egger and Jouret, though it is possible they were not the only ones.{{sfn|Bédat|Bouleau|Nicolas|2000|p=214}}{{sfn|Bédat|Bouleau|Nicolas|1997|p=220}} Following the deaths in Cheiry, Jouret was recorded as calling Di Mambro, possibly to inform him that it had been a success, and shortly after so did Egger.{{sfn|Bédat|Bouleau|Nicolas|1997|p=220}} On 3 October, Di Mambro was in Salvan; he, with several of the most faithful, were seen at a restaurant there. They were noted to have an "absent and sad air" and barely ate.{{sfn|Bédat|Bouleau|Nicolas|2000|p=215}} By this time Di Mambro may have already had his son Elie killed as a "traitor", the first death in Salvan: his body was found alone, off to the side from the others.{{sfn|Bédat|Bouleau|Nicolas|1997|p=222}} In a final, fifth note found in Di Mambro's chalet, blame for the Cheiry killings was shifted onto Jouret.{{sfn|Hall|Schuyler|2000|p=146}} Separately, the passports of Di Mambro and his wife were mailed to [[French Minister of the Interior]] [[Charles Pasqua]].{{sfn|Introvigne|2006|p=35}}

25 were found dead in Granges-sur-Salvan.{{sfn|Clusel|Palmer|2020|p=230}} Most of the bodies in Salvan were burned beyond recognition,{{sfn|Hall|Schuyler|2000|p=116}} and Jouret and Di Mambro's bodies had to be identified via [[Forensic dentistry|dental records]].{{sfn|Bédat|Bouleau|Nicolas|1997|p=23}} The dead had been injected with poison.{{sfn|Michaud|1996|p=10}} According to the investigative report, it is likely that the fatal injections at Salvan were done by Line Lheureux. A note found on Di Mambro's body, written by him, declared: "Your Transit must be assured of total success, but that depends on you."{{sfn|Bédat|Bouleau|Nicolas|1997|pp=223–224}} According to the coroner report, Di Mambro died of the drugs he ingested prior to the fire. His body was found in the first chalet in Salvan, on the intermediate floor, near the body of Emmanuelle.{{sfn|Michaud|1996|pp=23–24}} Jocelyne Di Mambro died in a similar manner, her body found in a room of the upper floor of the same building.{{sfn|Michaud|1996|pp=23–24}}

Mostly in an attempt to discourage devoted former members from visiting their graves, the location of the graves of Jouret and Di Mambro were not officially released, with authorities describing it as "top secret". As neither of their families came to claim their bodies, they were both cremated following their autopsies. According to journalist [[Arnaud Bédat]], who investigated the case, as the canton where the death occurred has jurisdiction in Switzerland, they were both buried secretly under an unmarked slab in a cemetery in [[Sion, Switzerland]].{{sfn|Bédat|Bouleau|Nicolas|1997|p=273}}

The Solar Temple disbanded after Di Mambro and Jouret's deaths, though in 1995 another group of 16 OTS members [[1995 Vercors massacre|committed suicide]] and in [[1997 Saint-Casimir mass suicide|1997 five more followed]], following the first group.{{sfn|Lewis|2004|p=296}}
