Perugia , Italy ( CNN ) -- Amanda Knox and former boyfriend Rafael Sollecito are killers and the evidence proves it , a prosecutor insisted Friday in wrapping up her statement in the duo 's appeal of their 2009 murder convictions . Knox and Sollecito were convicted of killing Knox 's former roommate , Meredith Kercher , in a bloody crime that left the victim half-naked with her throat slashed . Knox 's attorneys argued in their closing arguments Thursday that police had made numerous mistakes investigating the crime and that evidence did n't support the convictions . But prosecutor Manuela Comodi said the evidence is clear , from bloody footprints with particular characteristics that match the two to the very spot where Knox 's DNA was found on a kitchen knife believed by investigators to be the murder weapon . `` They are young , but so was Meredith . They 've murdered . And they have killed for nothing . And for this they must be condemned to the maximum sentence , '' Comodi said . The hearing was expected to continue Friday with an attorney for Kercher 's family addressing the court . No ruling is expected until Monday , when Knox and Sollecito are expected to give final statements , according to the judge . At Friday 's hearing , prosecutor Giuliano Mignini said Knox and Sollecito tried to blame the killing on another co-defendant , Rudy Guede , because Guede is black . Guede was also convicted in the case and is already serving a 16-year sentence . Comodi , showed jurors a photograph of a bloody footprint found in the bathroom of the home were Kercher was killed . There was no way the footprint was Guede 's as defense attorneys had contended , Comodi argued . Comodi said experts have concluded that the footprint was not Guede 's and probably was Sollecito . She also told the court that just because the footprint was found `` not usable '' for positive identification , it does n't mean that they are `` non usable ' '' when you can do a process of elimination . Comodi also used her microphone to demonstrate the how the location where Knox 's DNA was found on the presumed murder weapon -- at the junction between the blade and the handle -- suggests a stabbing motion , rather than a cutting motion . On Thursday , Knox 's attorneys gave their final arguments to counter prosecutors ' portrayal of her as a cunning `` femme fatale . '' Lawyer Carlo Dalla Vedova told the jury `` that the only possible decision to take is that of absolving Amanda Knox , '' as he wrapped up his closing argument . He said the court had seen no trace of Amanda Knox in the room where the murder took place . Another one of Knox 's lawyers , Luciano Ghirga , said she was `` very afraid but her heart is full of hope '' that she will be freed . Her `` image was massacred '' by the media and the attacks on her character started before the trial , he said , adding that he considered her as a daughter . Concluding an emotional appearance , he appealed to the jury to put themselves in the shoes of Knox 's family -- a counterpoise to the words of appeals court prosecutor Giancarlo Costagliola , who asked the jury to put themselves in the shoes of Kercher 's family at the start of the closing arguments a week ago . The `` clan Knox '' -- as Knox 's family have been referred to -- are not part of some rumored U.S. conspiracy to put pressure on the Italian courts to release her , Ghirga said . Rather , `` they are parents and they deserve respect . '' The lawyer also praised the court 's work , saying he felt Knox 's rights had finally been respected . Urging the jury not to let innocent people stay in jail , Vedova earlier detailed what he called many `` mistakes '' made in the investigation into Kercher 's death . When Knox was arrested and interrogated , she was not allowed a translator and was discouraged from getting a lawyer , Vedova said . `` 'That night Amanda Knox 's right to defend herself was denied , '' he said . `` She was just a young girl , first time out of the country . She did n't speak Italian . '' Vedova argued that some of the DNA evidence presented by the prosecution should be thrown out . He said some material was contaminated as a result of poor practice by police , including supposed traces of mixed blood in the bathroom sink shared by the two girls . The prosecution 's use of alleged bloody footprints in their case was also wrong , he said . As for the knife used to kill Kercher , a key piece of evidence , Vedova told the court there was a `` concentration of nothingness , a fantasy '' in the prosecution 's arguments . He ridiculed a theory that Sollecito had not disposed of the knife because he was concerned his landlady would notice it was missing , asking : `` What kind of a killer would think about this after committing a murder ? '' Knox and Sollecito were convicted in 2009 . Knox was sentenced to 26 years in prison , while Sollecito got 25 . CNN 's Hada Messia contributed to this report .
