After Amanda Knox's roommate Meredith Kercher was murdered in Italy in 2007, Knox spent four years in prison before being acquitted. The high-profile case has previously been the subject of a book, documentary and television series.
Now Knox is performing a comedy show at the prestigious Edinburgh Fringe Festival.
It is problematic to make a comedy out of the case, says the murdered woman's sister, Stephanie Kercher, in an interview with the BBC.
On social media, Knox rejects the criticism, which she believes is aimed at silencing her from speaking out about the injustices she has suffered.
