ROME (AP) — U.S. student Amanda Knox and her former Italian boyfriend have to wait another day to learn if they must stand trial yet again in Italy for the 2007 murder of her roommate.
Italy's top Court of Cassation put off until Tuesday morning its announcement of its decision on whether to definitively confirm their 2011 acquittals or throw out those verdicts and order what would be the their third trial.
Neither of the two came to court in Rome on Monday to follow the latest stage in their case. Knox was waiting for the decision in her home state of Washington, while her co-defendant and former boyfriend, Raffaele Sollecito, stayed in northern Italy to continue his studies.
The court heard six hours of arguments Monday and spent several hours deliberating that and a handful of other cases before announcing it would issue its decision at 10 a.m. (0900 GMT) Tuesday.
Italian prosecutors have asked the high court to throw out the acquittals for the murder of 21-year-old British student Meredith Kercher and order a new trial.
Kercher's body was found in November 2007 in her bedroom of the house she shared with Knox and other roommates in Perugia, an Italian university town with popular with foreign students. Her throat had been slashed.
Prosecutors have alleged that Kercher was the victim of a drug-fueled sex game gone awry Knox and Sollecito have denied wrongdoing, claiming they weren't even in the house the night of the murder.
The high court generally gives its rulings the day it hears arguments. But prosecutor general Luigi Riello told reporters that "in very complex cases, it happens" that the court takes another day.
A lawyer for Sollecito, Giulia Bongiorno, said the delay perhaps meant the court wanted "more time to reflect" before its ruling.
Sollecito's father shrugged off the suspense.
"We have waited so many years, one night is not going to make a difference," said Francesco Sollecito after some 12 hours in the courthouse, most of that time spent standing quietly in the back of the courtroom during final pleas by both sides. He said he hadn't yet spoken by phone with his son, who was in the northern city of Verona.
Knox, meanwhile, was waiting anxiously in Seattle to hear if her long legal battle was finally over, or if another chapter still needed to be written.
"She's carefully paying attention to what will come out," attorney Luciano Ghirga told reporters. "This is a fundamental stage. The trial is very complex." Ghirga had left the courthouse when deliberations began. He had left for the day by the time the court stunned fellow lawyers by saying they'd have to wait another day.
Knox, now 25, and Sollecito, who turns 29 on Tuesday, were arrested shortly after Kercher's body was found in a pool of blood.
In a first trial, both were convicted and given long prison sentences: 26 years for Knox, 25 for Sollecito. An appeals court acquitted them in 2011, criticizing virtually the entire case mounted by prosecutors. The appellate court noted that the murder weapon was never found, said that DNA tests were faulty and that prosecutors provided no murder motive.
After nearly four years behind bars in Italy, Knox returned to her hometown of Seattle and Sollecito resumed his computer science studies, following the degree he successfully earned while studying in prison.
Knox is now a student at the University of Washington, according to her family spokesman, Dave Marriott.
Italy's judicial system allows for two levels of appeals, and prosecutors can appeal acquittals.
Although the court on Monday heard gruesome details, including how Kercher choked on her own blood, it will not rule on the guilt or innocence of the defendants. Its sole task is to decide if the appellate trial was properly conducted.
