Amanda Knox

• Senator Maria Cantwell
On 4 December 2009, after the announcement of the verdicts on Knox and Sollecito, Maria Cantwell, United States Senator for Washington, stated that evidence against Knox was insufficient, that Knox had been subjected to "harsh treatment" following her arrest and that there had been "negligence" in the handling of evidence.
• Idaho Innocence Project
The Idaho Innocence Project, a non-profit legal organisation dedicated to proving the innocence of wrongly convicted people through the use of DNA testing, worked on the Knox and Sollecito case. On 23 May 2011, Dr Gregory Hampikian, director of the project, announced that, based on its independent investigation and review, Knox and Sollecito are innocent of the crime. Hampikian stated that more than 100 DNA samples taken at the crime scene pointed to Guede, and excluded Knox and Sollecito. Hampikian is a volunteer consultant for the Knox defence.
