That's not correct. Opening time of the 'minutes' marks only the official time the interrogation started.The 'interrogation' did not take many, many, many hours. It took about one hour. Interpreter arrived at 12:30am and statement was typed up at 1:45am.
According to Donnino Amanda was already being questioned when she arrived. Official minutes were opened at some time later. The interrogation lasted to "5am or a llitle before 5am" according to Giobbi.
Incidentally Giobbi also testified he ordered Amanda and Raffaele to be interrogated simultaneously that night. He says Amanda had been questioned before for 3-4 hours each time, but the night interrogation was "the longest", lasting from around 10pm to around 5am. They halted only then and passed her to Mignini.
