After 14 months of investigations, in September 2022 the first parliamentary commission concluded its work. In the final report the commissioners wrote that "the medical-legal cause of David Rossi's death must be identified as polytrauma and skeletal-fracture and visceral injuries, a direct consequence of the precipitation and impact of the body on the ground". However, there were many doubts that emerged from the parliamentarians' report. "Not all the injuries found on the body can be traced back to precipitation", the commissioners had written, believing "that the opinion expressed by the medical examiner during the first investigation in 2013 cannot be shared, in which 'it is claimed that the compatibility of the injuries reported with a suicidal gesture can be defined as 'full'"
The doubts about the case had therefore not been resolved and on 5 March 2024 the bis Commission was established to investigate the death of David Rossi. In March 2026, the members approved a mid-term document which states that the assessments carried out and the "clarifications given at the hearing by the same consultants in the sessions of 9 December 2025 and 24 February 2026" show that "David Rossi was the victim of an action with the intervention of third parties, therefore definitively excluding that it was a suicidal event, but rather a murder".
Finally, in September 2026, the first technical assessments on the death of David Rossi were made known after the simulations in Rome, with the help of the RIS, as part of the expertise requested by the Commission of Inquiry. According to what has been reconstructed, the man would have been attacked violently and quickly in his office by several people, at least two corpulent ones, and before falling from the window he was conscious, so he most likely tried to defend himself. Once he ended up outside the window he tried to cling to the edge and was held by the attackers, perhaps in an attempt at intimidation, but then the grip failed and Rossi fell.
On 19 October 2026, Gianluca Vinci, president of the Parliamentary Commission of Inquiry, stated during a meeting of the Bureau: "Based on the elements acquired by the Commission in the events that led to the death of David Rossi, Giuseppe Mussari would be involved, with different roles, as the instigator of an intimidation action which initially should not have led to the death of David Rossi, and Gabriele Ceccherelli, as the person who would have organized and chosen the people, currently not yet identified, to involved in the executive phase while remaining outside Palazzo Salimbeni himself. The Bureau had the opportunity to evaluate information elements acquired by the Commission's consultants in the context of some interviews with prisoners". Then he added: "We have decided to send the documents. We will send all the documentation to the Prosecutor's Office. The judicial authority will know how to proceed."
"It appears to us that there was no desire to kill David Rossi but to intimidate him", said Gianluca Vinci at a press conference, speaking of "an error in the execution of what had been requested". "The executive part would be missing from this reconstruction, that is, the people who physically entered Rossi's office - he added - All the legal aspects are not up to this Commission".
"The two indicated subjects are given the opportunity to be able to defend themselves with a completely new method for this Commission, that is, a sort of interrogation where there will be the assistance of a defense lawyer and the possibility of making use of the right not to answer - said Vinci - These are not subjects under investigation. This is also the opportunity to urge all those who have information on David Rossi's death to contact us or the judicial authority. It was a necessary step because as a Commission we have the objective of clarifying". Then he added: "The two testimonies collected agree on our reconstruction. Obviously if the two" who gave their names "lied to us who have the same powers as the judicial authority, they will be liable for the crime of slander".
