FLORENCE, Italy—Amanda Knox was back on trial for slander Wednesday for wrongly accusing a Congolese man of murdering her roommate while the young women were exchange students in Italy. Knox herself was convicted of the slaying before being exonerated in a case that grabbed the global spotlight.
Ms. Knox was a 20-year-old student with rudimentary Italian who had recently arrived in Perugia, when she endured a long night of questioning in the murder of Meredith Kercher. She ended up accusing the owner of a bar where she worked part-time of killing the 21-year-old British student.
