Andrea Pianese, the lawyer representing the Del Giudice family, which lost three relatives in the July 28th crash, said there were “no more doubts” that the vehicle’s brake system was broken when the tragedy occurred. The coach’s transmission was found on the highway close to where the accident took place in the Campania region, Corriere della Sera reported.
Gennaro Lametta, the owner of the bus company and the brother of the driver who died, is being probed as part of the investigation.
Two people who work for the highway service company, Autostrade, are also under investigation for poor guardrail installation and upkeep.
The crash happened in an area known as an accident black spot and investigators are looking into whether the barrier was high enough to withstand impact with larger vehicles.
The bus had been making its way back from a pilgrimage to Pietrelcina, with 48 people on board, when it careered off the road and plunged 30 feet down a slope.
