I spent years… literally… reading, discussing, and arguing about the fine details of this case on the Perugia Murder File forum (no longer in existence).
It was a board similar in many ways to the SDMB, and with many highly qualified people in relevant areas – senior police officers, forensic scientists, lawyers (Italian as well as British and American), as well as many intelligent people from all over the world simply interested in the case.
So I have no desire to rehash the whole case from the beginning here.
For anyone who wants to explore it further, here are some possibilities:
1. All the facts and evidence are collected and preserved on this site:
The Murder Of Meredith Kercher Wiki Site
The site has all the plain, detailed facts and evidence – leaving you to draw you to draw your own conclusions.
You can read the summaries and FAQs, or go down the rabbit hole and look at the evidence in as much detail as you like.
2. If you are interested in a video overview of the case, I suggest you watch the 1 hour BBC documentary I posted above (here it is again):
3. If you want to read about it, I recommend the excellent book, Death in Perugia by John Follain, reviewed here:
John Follain is the Rome correspondent for the Sunday Times and has been following the case since it began. His book is a neutral retelling of events, from the British student’s murder on the night of 1 November 2007 to that acquittal a few weeks ago on 3 October. Death in Perugia is not a first-person narrative, nor one that expresses an authorial opinion on the guilt or otherwise of those on trial. Perhaps because of this objectivity, it’s a gripping read: a balanced, detailed account that allows the reader to respond to the central question: did they or didn’t they?
