The three detainees had been aware of the failure of the safety braking system for weeks. This was stated by the chief prosecutor of Verbania Olimpia Bossi investigating the tragedy of Mottarone. With the manager of the Mottarone cable car, an engineer and a head of the service currently in a state of detention, there was a “discussion of a technical nature. They ‘justified themselves'” with respect to the aware anomalies of the system’s braking system “to overcome the economic difficulties and prevent it from stopping for a long time”. So it was decided to “defuse” the safety braking system on the crashed cabin, concludes the prosecutor Bossi.
