Amanda Knox: 'Railroad Job From Hell'?

Amanda Knox , the 20-year-old University of Washington student who's been held by Italian police since November as a suspect in her British roommate's murder, is the victim of a “railroad job from hell,”  an investigator hired by the “48 Hours Mystery” to review the case concluded. "They've put so much into Amanda Knox, they have to convict her now or they look like fools," he says on the show, broadcast last night.

A second investigator hired by the show disagrees, pointing to damning DNA evidence, including a bloody footprint that matches Knox’s boyfriend, who was also arrested, as well as a bloody knife, sink, and bra strap. Knox initially said she “heard Meredith screaming” but later reversed her statement. Still, a producer tells the Seattle Post Intelligencer, “it does feel from the wide shot that there are some real problems in this case. It's just not a clean case." Italian police can hold her for up to a year before filing charges. (More murder stories.)
