Sinister creaks, loud noises of failure in the Vardabasso classroom coming from the fixtures and from the ceiling: during the lessons on Tuesday, in the building of the Language faculty that collapsed at night when luckily there was no one left, many heard these signals . Something dangerous in the building, in the university center of Sa Duchessa in Cagliari, was about to happen as early as 4.30 pm: the confirmations came to the investigators who are carrying out the investigations coordinated by the Cagliari Public Prosecutor's Office for culpable disaster and culpable collapse of the building.
Some students who attended the lessons of Cultural Anthropology, at 4.30 pm, and Theory and History of Translation, from 6 pm, have already been listened to by the agents of the Flying Squad as well as the teachers. Also acquired photos of cracks and disturbing marks present in the classroom, as well as audio of the lessons. After one of the noises, a voice - that of the teacher - lets slip the phrase " as long as nothing falls ": a terrible presentiment which then became reality around 9.30 pm.
In short, the signs suggest that it was an announced collapse : and to think of the tragic outcome if it had happened a few hours earlier, when there were more than a hundred students in the classroom , gives chills.
Meanwhile, investigations are also continuing to establish the causes of the collapse. At work, under the coordination of the chief prosecutor Paolo De Angelis and the substitute Giangiacomo Pilia , the Flying Squad of Cagliari (which has seized the entire area affected by the collapse), the fire brigade, the ASL, the Spresal and the 'Ispra. And the policemen are acquiring documentation, plans and papers relating to the works carried out in the building dating back to the fifties and in the collapsed part, built ten years later. The research is carried out in the offices of the University, the Municipality of Cagliari, the Civil Engineers and in the bodies where there is evidence of the interventions carried out in particular in the Aula Vardabasso: born as a single environment, it subsequently housed several administrative offices (created with partitions), to then recently become a spacious classroom again with the demolition of these partitions-walls.
Nor can it be overlooked that the area (that of sa Duchessa, with the presence of karst cavities, caves and underground waterways) where the Faculty of Humanities is located in the past was affected by landslides and landslides : such as those of 2008 in via Peschiera and those in piazza d'Armi. Also on this aspect the technicians will carry out all the necessary checks.
Investigators let it be known that anyone who has recent images or videos of the two classrooms before the collapse (perhaps with signs of cracks), can contact the offices of the Police Headquarters . Just as anyone who has noticed or heard something strange in the last hours of class before the closure of the faculty building will be able to report everything to the Mobile police.
