Almost a year-and-a-half after her original murder conviction was overturned, the Italian supreme court has overturned that acquittal, opening the door for another sensational trial of American student Amanda Knox.

For those of you who managed to forget, the case began all the way back in 2007, when Knox and her then-boyfriend were accused of sexually assaulting and murdering her roommateMeredith Kercher. Knox, an American, and Kercher, who was British, were both exchange students at the University of Perugia in Italy. Knox and the boyfriend, an Italian man named Raffaele Sollecito, were convicted of the crime and spent nearly four years in jail before the convictions were overturned and both were released in late 2011. A third man, an immigrant from Ivory Coast named Rudy Guede, was also convicted in a separate trial.

The case became a tabloid sensation in all three countries, thanks to the ages of the two women—some in the press nicknamed her "Foxy Noxy"—the grisly nature of the crime, and numerous lurid accusations, like the original prosecution theory that Kercher was killed in a bizarre, possibly Satanic, sex game. Knox was also ordered to pay damages to yet another man who she accused of committing the murder.

Knox has since returned to United States, adding another layer of legal complications for prosecutors hoping to get a new conviction. Her Italian lawyer has already stated that she is unlikely to return to Italy for the re-trial, though she could be tried in absentia. She could also be extradited, either before or after the trial, although those proceedings could take months or even years and create headaches for diplomats on both sides of the Atlantic.

There have also been numerous books written about the case, but Knox has also written her own version of the story (that came with a reported $4 million advance) that is set to be released at the end of April.
