Next myth dispelled by Edgardo Giobbi is the length of the interrogation.
Edgardo Giobbi admits that each time Amanda was called to the station she was questioned for 3-4 hours. He states that the last time was the longest. He says it took from after 10pm to 5 or "a little before" 5am when finally they stopped and called Mignini.
We know the interrogation continued then, Mignini extracted another signed statement from Amanda.
