The Interrogation Was at Most Two Hours Long
One of the most common falsehoods concerns the length of the interrogation. Different stories report different lengths: There are stories such as above where the length is reported as 13 or 14 hours, stories where the length is reported as 18 hours, there is even the occasional story where the length is reported as 50+ hours, sometimes consecutive and sometimes broken up over the week. In more recent coverage a specific number is no longer used and instead the more ambiguous claim is made that it was a lengthy interrogation.
If someone were interrogated for those lengths there would be some reason to be doubtful about any statements that the suspect eventually made. In this case though all of that is simply made up. The longest the interrogation could have been is two hours giving Knox all the advantages possible. A realistic estimate would be about an hour. Amanda Knox started a phone conversation with her roommate Filomena at 10:29 pm.[23] Knox's first statement is timestamped at 1:45 am. We have to allow for the phone call and Knox's notorious police station cartwheel. Several police officers testified that at around 11pm Amanda Knox was doing cartwheels and the splits by the elevator.[24] Monica Napoleoni claims that she approached Knox at 11:30 pm. Anna Donnino who was Knox's interpreter also gave a time of about 11:30 pm for when the station called and informed her that they would need her services as translator, and arrived at the station at 12:30 am.[25]. Anna Donnino testified that the serious questioning started at about 12:30am.[26] So assuming an 12:30 am start that would mean there was only 1¼ hours for the interrogation. If one includes the time when Knox was just in the room waiting for the interrogation to start it is two hours. Knox placed herself at the scene and implicated Patrick earlier than when the statement was prepared so realistically it took Amanda less than an hour to confess.
As such, despite claims that the statement was the result of an "obsessively long" (Hellmann) interrogation, the facts are that Amanda changed her statement quickly and pretty much instantly when she was told that Raffaele was no longer corroborating her alibi. The parents, and now Knox on her book promotion tour, intentionally deceive people about the length of the interrogation so as to make the idea that it was a statement made under duress, and thus probably a false statement, more believable.
