“The gentlemen had been away from home for several days (Eugenia Madeddu and Duccio Ibba, ed) - declared Antonio Giordano, commander of the Nuoro fire brigade -. They returned in the evening, then on Tuesday morning they resumed their daily routine: they went to the kitchen, turned on the gas for the coffee. At that moment the detonation took place ”.
The trigger may have been this simple gesture repeated countless times . That is, prepare the coffee, turn on the stove. This would have unleashed that incredible explosion that crumbled the three-story house just outside Tiana. It caused the death of the spouses Marilena Ibba and Guglielmo Zedda.
Right from the start, the investigators directed their investigations and their attention to the city gas network. The villa surrounded by greenery on the outskirts of Tiana, on the road to Ovodda, was in fact served by the Bimgas consortium .
"The house came down, it was crumbled because there was a considerable amount of LPG inside - continues Giordano - now we have to check if there has been an overpressure, a continuous leak, if the so-called pocket has formed and where ".
Engineer Carla Corimbi confirms: “Let's start from an assumption: the gas must be in the pipes. If this does not happen, and what happened in Tiana, it can generate a build up of gas in an uncontrolled place . The contact with the air, then, will lead to the explosion, just like in the case in question ”.
Meanwhile, in Cagliari the coroner Roberto Demontis performed an autopsy on the body of Guglielmo Zedda. The death of man occurred by crushing . On Friday, the examination on the body of his wife Marilena Ibba is scheduled. The couple's funeral is expected to take place on Saturday in Tiana.
