British DNA expert Dr. Peter Gill has joined the list of DNA experts who have disputed the results that led to the conviction of former student Amanda Knox in the 2007 murder of Meredith Kercher in Perugia, Italy.

In the recently published book, authored by Dr. Gill and entitled 'Misleading DNA Evidence: Reasons For Miscarriages Of Justice', the English DNA expert points out several factors that he believes may have contaminated the crime scene in Perugia which put Knox and her then-boyfriend, Rafaello Sollecito, in what the DNA expert claims, as circumstantial evidence. Knox was a roommate to the deceased Kercher during the time of her death.

An entire chapter in the book was dedicated to Dr. Gill's take on the evidence gathered in the Italian murder and has particularly focused on two major pieces amassed from the crime scene which were said to have been the keys to Knox's and Sollecito's conviction - a knife gathered from Sollecito's kitchen and a hook from Kercher's bra which was said to have contained Sollecito's fingerprints.

The British DNA expert emphasized in the said chapter that he believes that both evidences may have been contaminated during the investigation conducted by Italian authorities.

Knox and Sollecito were both re-convicted January of this year, where Knox was sentenced to 28 years in prison while Sollecito also received 28 years of imprisonment.

Both suspects in the Italian murder case have formally submitted their appeals to the Supreme Court of Cassation and will be awaiting verdict by early 2015. Knox previously stated that she "will never willingly go back to Italy again".
