BOISE, Idaho (KBOI) -- Amanda Knox, 26, was convicted on murder charges for a second time. An Italian appeals court set a 28.6 year sentence for her and a 25 year sentence for her ex-boyfriend Raffaele Sollecito.
Knox was not at the trial in Italy, but instead watched it from her hometown in Seattle. CNN reports it is unlikely Knox will go back to Italy for jail time because U.S. dictates that a person cannot be tried twice on the same charge.
Boise State University professor, Dr. Greg Hampikian, and several students did DNA testing that was connected with the trial back in 2011. He was in close contact with the defense lawyers during her the trial with his findings. Hampikian said he was shocked that the Italian Supreme Court appealed the case last March.
"I believe she's innocent for the same reason you're innocent and I'm innocent... There's no evidence tying us to that crime," Dr. Greg Hampikian said.
In 2007, Knox and her Sollecito were arrested and charged with killing her roommate, Meredith Kercher, while studying abroad in Perugia, Italy. Kercher was found dead with more than 40 stab wounds and a deep gash in her throat. Two years later the couple was convicted in Italian Court. After spending four years in prison, the Italian court overturned the ruling for a lack of evidence and both Knox and Sollecito were freed.
Dr. Hampikian said the only evidence the courts had to convict Knox and Sollecito was a knife found at the scene. He argues there wasn't enough DNA on the knife to convict the couple, and said Italian investigators could have also contaminated the evidence during the investigation.
"We’ve seen in the collection of evidence from this case that there were dirty gloves; they weren't’t changing gloves, and they were handing evidence from one person to another and they even put evidence on the floor as they were collecting the evidence, which is just shocking,” Dr. Greg Hampikian said.
Hampikian mentioned the knife had very little DNA on it.
"We showed by similar, sloppy practices, it’s very easy to transfer few cells onto a knife, when we hadn't actually touched that knife," he said. "The original DNA that got onto a glove of a analyst got transferred to a knife.. we showed that that was possible. That might have happened in this case."
But, almost a year ago, in March 2012, the Italian Supreme Court decided to retry the case, saying the jury didn't consider all the evidence in the testimonies given in court.
A third man, Rudy Guede, has been convicted of the crime in a separate trial... he is serving a 16-year-sentence.
"The fact that they arrested these young students, five days after the crime, before they had DNA, before they had fingerprints, and then when they get the fingerprints the DNA of this other guy, Rudy Guede, why didn't they just let them go?" he said.
