Judge in Amanda Knox case orders new DNA testing

[davidn3600]

An Italian judge presiding over the newest trial of Amanda Knox today ordered forensic experts to test a new "trace" of DNA on a knife that prosecutors claim is the weapon that killed Knox's roommate Meredith Kercher.

The judge also told the experts to alert the court whether it is even possible to test the trace for DNA because previous forensic experts said they believed it was not sufficient.

The DNA on the knife has played a key role in the first two murder trials of Knox, 26, and her ex-boyfriend Raffaele Sollecito, 29.

The pair was originally convicted of the 2007 murder in Perugia partly because forensic experts said they found DNA from Knox and Kercher on a knife in Sollecito's apartment.
