To overcome the barriers that make the smartphones of the elderly couple found dead in early December in Via Ghibli and of their 44-year-old son arrested less than a month later on suspicion of having poisoned them inviolable, the investigators of the RIS of Cagliari have sent all the cell phones to Rome, to the laboratories of the barracks "Salvo D'Acquisto", where their colleagues from the capital work and where the Racis, the Carabinieri Scientific Investigations Group, is based.
The experts
The Information Technology Department (divided into the IT, electronics and cybernetics sections) will therefore carry out the technical-scientific investigations on the cell phones, computers and software installed in the devices seized both at the homes of Luigi Gulisano and Marisa Dessì, 79 and 82 years old, and of their youngest son Claudio, arrested on December 30 on suspicion of having killed them and then transferred to prison in Uta on the preliminary investigations judge's order for precautionary custody. The prosecution suspects him of aggravated double homicide, but the 44-year-old - defended by the lawyer Luigi Sanna - immediately professed himself completely uninvolved in the facts. The experts from the RIS in Rome, who have worked on some of the biggest national cases, will therefore have to analyse the content of the chats and the internet searches carried out through the devices and with the PCs, so as to clarify whether there are elements useful to the investigation that can be extrapolated. But the very need to deploy investigators from the Capital could delay the results of the unrepeatable technical investigations on the computer equipment, where answers to too many questions still unanswered are being sought.
Suspicion about debts
In the meantime, the Carabinieri of the San Bartolomeo barracks, together with their colleagues from the Company's Operations Unit and the Prosecutor's Office, are reconstructing the details of Claudio Gulisano's life to understand whether the report, received in July of last year, about alleged debts that would have led to continuous requests for money from his parents, is real. This was revealed by a soldier who, it seems, had received the elderly couple when they showed up at the barracks. According to the story, they were worried about the continuous requests for money from their 44-year-old son, but in the end nothing was written down.
The Mystery of the Scarf
In recent days, the Carabinieri have also reportedly interviewed some witnesses regarding a scarf (apparently owned by Luigi Gulisano and Marisa Dessì) that was seized during one of the raids in the house on Via Ghibli, where the lifeless bodies of the elderly couple were found on the afternoon of December 5, lying in the study of the house. The time of death has not yet been clarified: the investigators suspect that they died the day before, perhaps before lunch, given that no traces of food were found in their stomachs. However, traces of “sodium nitrite” were found in the digestive tracts of both, the substance that – according to the forensic doctor Roberto Demontis and the toxicologist Giampiero Cortis – would have left them no chance.
The serious clues
At the moment, only serious evidence weighs on Claudio Gulisano: the main one is a message (sent from his father's phone on the morning of December 5) that would justify transfers made to his advantage from his parents' account (we are talking about 20 thousand euros). According to the prosecutor Rossana Allieri, that message would have been sent when the couple were already dead. The other son of the couple, Davide Gulisano, is considered unconnected to the facts: he is represented as an injured party by the lawyer Gianluca Aste.
