in the house the night of the murder and saw her boss, nightclub owner, patrick lumumba and meredith kercherith's room and she heard screams. her statement adds i am very confused, i imagine what could have happened. police apparently didn't bother to check the facts about lumumba. they immediately arrested amanda knox, rafaelle sollecito and patrick lumumba for the murder of meredith kercher. police announcing to the public, case solved. mignini admitted to us, even without any evidence, he knew almost the moment he arrived and laid eyes on amanda knox and raffaele sollecito, they were involved in the murder. >> prior to the forensic investigation, prior to everything really, your intuition or your detective knowledge led you to amanda knox and rafaelle sollecito? >> translator: after the first few weeks we were convinced because of the behavior of the two people and especially amanda that they were both involved in a crime. >> reporter: but almost immediately after the arrests, mignini had a problem. the third suspect patrick lumumba had an airtight alibi. he was in his crowded bar that ni

rudy guede, a local drifter, and the third person convicted for the murder of meredith kercher. guede's bloody hasn't print, seen here on the wall of the crime scene. his fingerprints on her bra. >> there is lots of dna and there are fingerprints from rudy. there is none from amanda knox. >> reporter: guede admitted himself he was in the cottage, but did not participate in the crime. this week, he took the stand, and toddress claims by follow inmate that he told them knox and sollecito were not in the house that night. he said that is not true. >> i was hoping rudy would own up to his responsibility and essentially tell the court that amanda had nothing to do with it. >> reporter: ultimately, the truth may simply come down to science. >> i think the story of how this crime was committed doesn't fit the evidence collected. >> please, please, you guys. >> reporter: knox's family has defended her and visited her in prison since day one. this isn't going to be over any time soon. how do you continue on through -- >> you have to. you stay focused on amanda. and making sure that that

in addition to knox and her ex-boyfriend, guede is the third person found guilty of murdering meredith kerchert the italian house she shared with knox in 2007. now fast-forward to today, knox still insists she's innocent. i spoke with her father earlier. we'll hear from him in just a moment. but first, let's get straight to our dan rivers who is inside the courtroom in italy. he joins us now. guede was called as a witness to talk about something that he told another inmate that knox and her boyfriend were not involved in this murder. but that isn't exactly what happened. >> reporter: that's right. just to put viewers in the picture, rudy guede has already been convicted of killing meredith kercher, along with the other two. his appeal process has been exhausted and he's now being called as a witness by defense lawyers for amanda knox and rafaelle sollecito to try to overturn their convictions. they were hoping undhe would cr and say that amanda knox had nothing to do with it. the exact opposite happened. rudy guede said that he always thought that amanda knox and sollecito were guilty and that

he is also convicted of meredith kercher's killing. and this man insists that guede told him neither amanda knox or her then boyfriend had anything to do with kercher's murder. several other prison inmates were called to try and support that story. and then the final witnesses of the day, yet another prison inmate, told a completely different story altogether. this was a man who was serving 16 years for mafia-related crimes. he says his own brother, and another man, were responsible for killing meredith kercher. he says he doesn't know where his brother is or who the other man was. if you don't give a clear explanation about why he was coming forward with this information at this time. >> phil black, thanks so much, for that update. >>> it is a simple idea. making sure people everywhere have soap. the problem is 2 million children die every year because of poor sanitation problems. idns drifting into the other lane.

meredith kercher was found dead.lian court convicted knocks' boyfriend and in a separate trial, another man named rudy guede who knocks and her family said she was railroaded into hoping the appeal would set her free and most experts think the appeal hinges on the forensic evidence. independents are looking at it again. today, amanda knox' defense team took another crack at this guy rudy guede. dan rivers is there and i spoke with him earlier. dan, how was amanda knox' defense different in this appeal than the first trial. >> this appeal differs in two crucial ways. firstly, they were able to question new witnesses, requested by the defense that they were unable to question the first time around. now, these are people, prisoners, that rudy guede has supposedly confessed to inside prison, saying that he thought amanda knox and her then-boyfriend rafael sollecito were innocent. since he's coming in and given evidence, he's flatly denied talk about the case at all in prison. the second important strand that's different

village of perugia, was found guilty, along with her former boyfriend, of killing her roommate meredith kercher after a wild night of alleged drugs and sex. she fought the charges, her family arguing that rumors in the italian press about her sex life had tainted the jury, that there was no evidence linking their daughter to the scene of meredith's death. nowhere in meredith's room, where the murder took place and where meredith's body was found, is there a single fingerprint from amanda, a single piece of dna from amanda, a hair. >> nothing. >> nothing. >> absolutely nothing. >> reporter: knox has already spent nearly four years in prison. >> i am definitely more hopeful that, when this is all over, that here in septptber, that she will be coming home with us. absolutely. >> reporter: the experts findings will be considered in court next month, late july, with amanda knox once again making the case that she is innocent. then, september, george, is when the court is expected to make a ruling. they may overturn her conviction and possibly set her free. >> this could happen quickly. >> reporter:

with a knife, he forced the victim, meredith kercher to have sex before he killed her. that is potentially going to be challenged, though, by another convict, matia turncoat who says his brother who's still on the run killed meredith on a break and enter. that brother cannot be found. so very, very confusing but simple casts some doubts. >> jeffrey, is amanda relying solely on the testimony of these five prisoners or is there something else to use to appeal her conviction? >> reporter: for her sake, you got to hope not because these guys really do not have much credibility. no. there's something much more important that we're waiting for, and that's the dna. she and her ex-boyfriend were convicted based on dna samples found on a knife and the bra clasp. they were very small samples. the bra was found a long time after the murder. now, they're being re-examened. what we're waiting for, and what amanda is waiting for, are the results of the dna evaluation. is it credible? does it hold up in court? because if it falls apart, the case goodness her could fall apart, and that

they are all expected to testify that a fellow prisoner also convicted in connection with meredith kercher's murder told them knox had nothing to do with it. that prisoner through his attorney denies saying anything of the sort. >>> and a fix to a computer problem that grounded united airlines flights across the u.s. but the airline says passengers could still experience delays throughout the weekend. the airline blames a network connection malfunction for freezing up the system that schedules departures, reservations and processes passengers. the glitch left thousands of people stranded and very frustrated. >>> an american eagle flight attendant is accused of stealing another man's identity to get a job that allowed him to fly all over the world. police say this man assumed the identity of a new york man and had several documents in that man's name including a passport. porter, who's reportedly an illegal immigrant from guyana, was arrested in miami yesterday. >>> and there is talk of a diplomatic breakthrough in afghanistan. afghan president hamid karzai told a youth group today the united

at amanda knox and her then boyfriend raphael sollecito and said he always felt they killed meredith kerchers allowed to dramatically speak in this hearing. one of the rare occasions. she has been able to speak in this appeal process. she said as you said, she was shocked by what guede said. she said he knew we weren't in the house at the murder. the only time the three of us have been together is in court. i don't know what happened. i'm sorry, i didn't have the opportunity to talk to him myself. and sollecito spoke and said their lives have been ruined, been in jail for four years and he guede knew what happened and by implication they've been convicted only on his evidence and supposition and that the rest of the case was weak. >> dan, this case has taken on so many twists and turns, stretched across four years now. there is any time frame for a ruling on this appeal? >> well, this will all now shift towards the forensic evidence. the hope for defense players here is that rudy gau day would sort of collapse and basically admit that he did it on his own, that seems to have evaporated. they

, serving 26 years in an italian prison in for the killing of her roommate, british student, meredith kercherfter. knox and her ex-boyfriend are hoping that this appeal will clear their names. the defense has called five witnesses. all claiming to have information that will do just that. but all serving time in prison for an assortment for ugly crimes. mario alesi, a convicted child murderer, told the court that that drifter, gede, was the only one involved in kercher's murder. that would be key evidence for knox and her family. >> rudy has said, as he has said in the past, that amanda and raphaelle weren't involved in the crime. >> reporter: another convict, a former mafia member, told the appeal a completely different story. the mobster said it was his own brother who murdered kercher, during a robbery that went bad. that brother is nowhere to be found. amanda an her ex-boyfriend, meanwhile, are back in prison. fortunately for knox, she may have new evidence that is a lot more credible than those guys. the key evidence in the appeal is the tests being done on the tiny amount of dna that hel

convicted and sentenced to 26 years in prison for the 2007 killing of her british roommate, meredith kercherto sit through testimony from the man who helped convict her and her former boyfriend, rafael sollecito. rudy guede has never denied he was in knox's apartment the night kercher was killed. investigators found his dna all over the crime scene, including bloody hand prints on the wall. he was sentenced to 16 years in this case. last week his cell mate mario alessi testified guede told him knox and sollecito were not involved. guede denied those claims and maintained the two were responsible. knox later told the court "he knows we were not there. i'm shocked and anguished by his statements." knox's mother was present at the hearing. >> it's unfortunate that he refused to answer questions. that would have been nice if he'd just gotten up and told the truth but that didn't happen. >> reporter: the court will be reviewing a report by independent forensics investigators on dna collected from the scene. evidence that could prove knox was not involved.ç >> you know, we're really hopeful. becau

experts reviewed what was collected from the scene of the murder of her roommate, british student meredith kerchertaminated and that they fell below international testing standards. it punctures a key argument that helped sway jurors, that both knox's dna and that of her roommate were found on the knife used to kill kercher. >> the report said exactly kind of what was our experts said all along, that correct procedures were not followed, that they can't rule out contamination. we can't really celebrate until amanda walks out of that prison. but this is just one big step in that direction. >> reporter: in 2009, knox was an exchange student from seattle studying in italy when she was arrested. knox and her then-boyfriend, rafael sollecito, were convicted in a trial that captured the nation. she was sentenced to 26 years. throughout it all, she has maintained her innocence. her family is hoping her appeal has a different outcome than her trial. >> i am definitely more hopeful that, you know, when this is all over, that here in september, that she will be coming home with us. absolutely. >> reporter:

the third person convicted of murdering meredith kercher in 2007. there has been little doubt about his guilt. unlike amanda knox and her former boyfriend, his dna is all over the crime scene. today, he'll deny reports that he told fellow inmates that knox and her boyfriend had nothing to do with the crime. guede has always admitted he was in the cottage knox shared with kercher the night she was killed, but did not arts pate in the crime, he said. instead he was listening to the ipod in the bathroom when intruders murdered meredith. amanda's mother, edda mellas is in court this morning to hear his testimony. guede's testimony is one of two key elements in this proceedings. the other independent review of crucial dna evidence. including trace evidence of kercher's dna in sollecito's apartment. and sollecito's own dna found on kercher's bra clapse. that wasn't enough evidence on the knife to be tested. the defense points out the absence of knox's dna from kercher's bedroom, where there is plenty of guede's dna, including bloody handprints on the wall

cross examination and would admit that it was he and he alone who murdered the british student meredith kercherr the first time, he said he explicitly thought that knox and sollecito were guilty of the murder, something he had only implied in testimony previously. there was also a dramatic moment when amanda knox herself made a statement to the court during the statement she said she was shocked by guede's evidence. she said he knew that we weren't in the house on the night of the murder. she said she didn't know what really happened, and she said she was sorry that she couldn't talk to guede direct to question him about the events. as well as her statement, raffaele sollecito spoke to the court and said that before guede had only mentioned a shadow he thought may have been amanda knox in the house that evening. now he seemed to be changing his story. he said that they had been in jail for four years and that their lives have been ruined, all on the evidence really of this one man, rudy guede. in the end, though, this defense attempt to try and get rudy guede to trip up in cross examination bac

new witnesses say she and former boyfriend raffaele sollecito are innocent of the murder of meredith kercherso been convicted of the murder. a third convicted child killer mario alessie. a fellow inmet who said rudy guede told him his friend killed kercher. >> we're hoping more truth comes out that these stories about rudy and him speaking while in prison to the fact that amanda had nothing to do with this, that it's proven in court. >> reporter: but that's just one version. a second witness convicted mobster lucian op. salievllo insists his mother murdered kercher during a botched break-in. today's testimonies are the latest twist in knox's lengthy and ongoing appeal process. the 24-year-old seattle student and her former boyfriend were convicted 18 months ago for the fatal stabbing of 21-year-old kercher in the bedroom of the house they shared in the italian mountain village of perugia. she's serving a 26-year jail sentence, but in recent months, there have been growing doubts over the strength of her conviction. a final decision in knox's appeal is expected in the fall, but key to the cas

sollecito, is appealing her conviction of murder and sexual assault of her british roommate meredith kercherone wrong. a third person, rudy guede, was also convicted of the murder. today's hearing focuses on the testimony of five convicts, all who claim knox and her ex-boyfriend are innocent. mario alessi, a convicted child murderer seen here speaking with sollecito's team said while sharing a cell with guede he was told the true story had not come out. three other prisoners are expected to claim they, too, heard the story and knox and sollecito were not involved. another prisoner, a convicted mobster, claims it was his brother who murdered kercher. he, to knox's defense, is the re-examination of forensic material, by an independent panel of scientists appointed by the appeals judge. leaks in the italian media so far suggest that the dna evidence used to convict knox could prove inconclusive. a bra clasp linking sollecito to the crime scene is said to be so badly rusted it cannot be retested. and a knife prosecutors claim was used to murder kercher appears not to have the dna of knox and the

for the first time, rudy guede, convicted with knox for the murder of her english roommate, meredith kercher, provided no help. last week another prisoner testified in court that guede told her amanda was not present at the killing. light at the end of the tunnel for amanda's family. >> it's huge. it would be the single biggest thing in the case. >> but today guede said it wasn't true, that he didn't tell alessi anything, that alessi had lied. but why would he lie? guede's lawyer put it down to simple prison gossip. >> in prison there is many, many, many, many, many people that know the mystery of every case. >> reporter: it may not be that simple. two other prison inmates also testified that guede told them amanda knox was not present at the murder. so who's lying? mario alessi or rudy guede? another critical question that could help determine the fate of amanda knox. the biggest question of all, though, is is the dna. >> i'm assuming that these people are professionals and that they're going to do a good job of relooking at this, and we know that amanda's innocent and so we can only hope a
