Amana Knox's murder case would reportedly have been thrown out of the court had the Italian justice system followed the global standards on DNA testing.

Greg Hampikian, a professor of biology and criminal justice at Boise State University and director of the Idaho Innocence Project, said the whole case was anchored on the argument whether or not a single result is enough to convict somebody.

For example, in the case of the Amanda Knox's murder case trial, the kitchen knife found at Raffaele Sollecito's house didn't match many of the wounds on Meredith Kercher and also "tested negative for blood."

"DNA from Knox was on the handle - she had cooked with it," he wrote on the New Scientist. "But on one swab from the blade, a minuscule trace of DNA was detected, just once during many analyses. It had some that was consistent with the victim's. This finding was never repeated, despite many attempts."

"In Knox's case, the DNA on the blade came from so few molecules that analytical instruments were pushed to read below the level that the FBI, my lab, or anyone I knew would go," he added.

The Idaho Innocent Project asked from the Italian laboratory that conducted the DNA testing on the Amanda Knox murder case trial for validation but it didn't send any.

As the name suggests, The Idaho Innocence Project helps exonerate innocents who are in jail through the use of DNA. Currently, the project is not accepting any cases due to funding constraints.

However, despite what he described as flimsy DNA evidence, Amanda Knox was convicted in the murder case.

He said, "DNA experts in the US spoke out and a new study on the knife was then ordered in Italy. This failed to repeat the DNA finding, and Knox and Sollecito were freed on appeal in 2011."

"Then in 2014, the conviction was inexplicably reinstated. The final hope rested with the supreme court this March. Justice would require it to see that there was no credible DNA evidence. Apparently it did," the professor added.
