before he died. abc's matt gutman has more. >> reporter: a trove of never before seen evidence collected by police. that fateful night. here, clear pictures of george zimmerman taken at the police station just hours after he shot trayvon martin. you can see what appears to be a swollen nose. the back of his head cut and bleeding. and in this newly released document, an officer on the scene notes zimmerman's nose appeared to be broken. and look at this grainy photo taken as zimmerman was sitting in the police car just moments after the shooting. there, too, his nose seems swollen. a doctor report first obtained by abc news reveals it was broken. also released, a chilling image of a gun zimmerman used to kill the unarmed trayvon martin. this document shows a police officer called the shooting, quote, avoidable, had zimmerman, quote, remaind in his vehicle and awaited the arrival of law enforcement. >> are you following him? >> yeah. >> okay. we don't need you to do that. >> okay. >> it's one reason a source tells abc news police doubted zimmerman's claim of self-defense that night and filed this recommendation for his arrest. what remains a black hole here is what triggers that conflict between trayvon martin and zimmerman that night. of course, that will be much debated in the courtroom when this trial finally gets under way. matt gutman, abc news, sanford. and that has to be key in this investigation. and once it eventually gets to trial, police told him to stay where he was. stay in your car. don't follow this child. >> that's been a key sound bite since this started. also included in the witness interviews were accounts by an acquaintance of george zimmerman's who said zimmerman is a racist. also a co-worker who said zimmerman bullied him and mocked him using an exaggerated middle eastern accent. so if that stuff is coming out in his behavior, that lends creedence to the idea this was perhaps racially motivated. still some rough altercation took place. the key question, what triggered it and who jumped first. >> and what's also actually really tragic about this and it becomes more and more trag sick one of the witnesses, the eyewitnesses told police that officers arrived five seconds after that shot. the fatal shot that killed him. >> so far away from trial. lots of miles to go. a downtown louisville neighborhood has been rocked by an outbreak of vilent gunfire. when that scene was over, three people were dead. two others hospitalized after two shootings. for now, police are still trying to sort out what happened and why saying only that the two incidents appear at this point to be unrelated. >> scary scenes. jury deliberations are getting under way in north carolina today in the john edwards campaign corruption trial. >> closing arguments, the two sides painting two very different pictures of what was really going on with all that donated money. abc's scott goldberg has more. good morning to you, scott. >> reporter: good morning, rob and diana. it is now up to the jury to decide if john edwards is guilty of the six charges against him, and if he is he could be headed to prison for up to 30 years. as a presidential candidate, john edwards talked famously about the two americas. one rich, one poor. but as a defendant charged with using campaign money to cover up the sex scandal that threatened his candidacy, he heard his own slogan used against him. campaign finance laws are designed to bring the two americas together, prosecutor bobby higdon said in his closing arguments and, quote, john edwards forgot his own rhetoric. the government argues edwards masterminded the plan to have fred baron and bunny mellon pay more than $1 million, far beyond the personal limit for campaign contributions to hide his mistress rielle hunter from the public. the prosecution called it a full rescue operation for a teetering campaign. but the defense argued the money came from a series of personal gifts to hunter. it never went into a campaign account, and edwards was most concerned about hiding the affair from his dying wife, elizabeth. john edwards has confessed his sins, defense lawyer abby lowell told the jury and, quote, he will serve a life sentence for those. but he has pleaded not guilty to violating the law. the jury now decides if edwards really was trying to protect his family or if he also was trying to protect his campaign. the jury begins deliberating later this morning. rob and diana?

before his death are released. >> along with new photographs of the suspect george zimmerman who was injured that night. it's friday, may 18th. >> announcer: from abc news, this is "world news now." >> good morning, everyone. thank you for joining us. i'm diana perez. paula faris is on assignment. >> you made it through your first week. congratulations. >> i made it. >> finish strong. you'll sleep well this weekend. trust me. >> can't wait. >> good morning, everybody. happy friday. i'm rob nelson. we'll explain the new developments in the trayvon martin case coming up. then we'll take you to california where a man who crashed his truck and was thrown from the wreckage was not found for more than a week. his relatives have tough questions for both police and paramedics. also, the life and death of donna summer. you couldn't help but get into a dancing mood when her music played. hear what she had to say about her own career. >> very interesting genesis to that famous song "she works hard for the money." and to hear it from donna herself. really cool insight into her career there. and later, al gore is back in the headlines, and not because of his politics or even his stance on the environment. those well known views. it has to do with his marriage. that is coming up in "the skinny." >> also very interesting. >> al could be back on the sce a little bit, looking for greener pastures, shall we say. >> maybe he already found it. >> you never know. but first, the more we learn about the terrible night trayvon martin died, the more tragic this becomes. we've learned a mountain of new details from nearly 200 pieces of evidence that prosecutors just released. >> among them, the last images of trayvon martin alive. surveillance video from the convenience store shows the teen buying the skittles and iced tea shortly before police found his body in sanford, florida. abc's t.j. winick has more. >> reporter: we now know that trayvon martin, the 17-year-old who was shot and killed by george zimmerman, had the marijuana component thc in his system the night of his death. zimmerman was charged with second-degree murder even though we now know one police investigator wanted him charged with manslaughter. the autopsy also revealed martin was shot from a distance between 1 inch and 18 inches away, bolstering zimmerman's claim he fired during a struggle that landed zimmerman on his back, martin straddling him and banging zimmerman's head on the ground. and pictures at the police station after the shooting show zimmerman's face which appears marked and the back of his head which is clearly lacerated. in this newly released document, an officer on the scene notes zimmerman's nose appeared to be broken. also released, a chilling image of the gun zimmerman used to kill the unarmed martin. documents show a police officer called the shooting, quote, avoidable had zimmerman remained in his vehicle and awaited the arrival of law enforcement. in a review of the cause, it was determined that george zimmerman yelled help or help me 14 times during approximately 38 seconds. trayvon's own father confirmed the voice on the recordings was not his son's, contradicting statements he would later make. t.j. winick, abc news, new york. >> a lot of new evidence coming out on this. obviously, 200 pieces. one investigator, to reiterate, said the whole thing could have been avoided if zimmerman had simply stayed in his car and waited for police to get there instead of taking matters into his own hands. again, the key question here is that -- still not clear who provoked what? >> what happened? >> that's the thing. >> as we've been saying, that is the black hole in the investigation. how did they end up where they were on the floor during this altercation? that's what everybody wants to know. why did he pull the trigger? >> also some discrepancies about the family saying about the voice calling out for help because there was a help or help me heard on the tape 14 times. the mom initially said, yes, i recognize my son's voice. dad said, no, it's not. now the lawyers say, no, the tapes have been cleaned up and dad saying, yes, that is our son's voice. a little back and forth. more evidence but with more evidence comes more questions. >> there are a lot of questions with this investigation. >> absolutely. also another major headline this morning. we are remembering donna summer, the queen of disco. she was the voice and the face of the '70s. and its glittery, exuberant dancing back then. her breathy and sexy "love to love you, baby" was the first of her 19 number one dance hits. that is second only to madonna. it's impossible to listen to any of them now and not still, even today, want to get up and dance. >> i think what donna brought to the world with her music was a lot of happiness to a lot of people. >> donna summer is definitely a giant in the music industry. she got a lot of people out of their chairs with all of her dance hits. >> according to reports, summer died of lung cancer at her home in florida. she was just 63 years old. her family released a statement saying they are at peace, and they are celebrating her extraordinary life. and also details being reported by tmz that there will be a public memorial that will take place in nashville this coming wednesday. our remembrance of donna summer does not end here. we want to hear what donna summer had to say herself about the music that kept so many of us dancing. that's coming up in her own words later in this half hour. >> it's pretty incredible. not only the back story about "she works hard for the money," but there are back stories to all of these songs. this "love to love you, baby," she recorded it laying on her back in the recording studio envisioning what marilyn monroe would coo and how she would say these words. that's how it became so breathy and sexy, which at the time -- >> it was raunchy for its day. it was like, whoa. people backed away from it. people wouldn't play it because it was that out there. funny that marilyn was the inspiration. that all-american icon of sexy. that's who she was emulating on the floor in the recording studio. it's still a sexy song. it still works today. >> oh, it does. >> miss summer knew what she was doing. she didn't want to be remembered for sexiness. she wanted to be remembered for making songs that would outlive her, which they will. >> and they will. that's exactly what she was able to do. moving on to north carolina where jurors will begin deliberations today in john edwards' conspiracy trial. in closing arguments, prosecutors said the one-time presidential candidate would, quote, deny, deceive and manipulate at every turn to protect his political career. his defense attorney said what he did was a sin, not a felony. edwards could go to prison for up to 30 years if he's found guilty. the key prosecution witness in the roger clemens perjury trial will testify for a fifth straight day today. in his latest round of cross-examination, clemens' former trainer brian mcnamee admitted he has mixed up some dates and some details and even embellished his story to investigators. but he is still sticking with his main story that he did inject clemens with steroids on several occasions starting back in 1998. and two former florida a&m band members have been sentenced to 30 days at a work camp on probation -- and probation for hazing a female clarinet player last fall. aaron golson and sean hobson pleaded no contest in the beating of freshman bria hunter. that incident took place just three weeks before the hazing death of drum major robert champion. golson is also 1 of 11 students charged in champion's death. a northern california man has been found alive, but critically injured a full week after his car rolled over into a wooded area near a busy highway. investigators found michael sanchez's pickup right away, but it took another seven days before they actually found sanchez himself under a bush unconscious. his family is understandably upset and also wondering what took so long. >> in hindsight, no, you know, it didn't work out the way it was supposed to work out. and nobody is happy about that. >> he's 25. he's young, and he's strong. and that's why he was able to survive. >> his prognosis is still unclear. for now, sanchez is hospitalized and is on life support. we are just hours away from a wall street frenzy like none other. one of the biggest public stock offerings in history. just eight years after mark zuckerberg launched facebook, stocks will start selling this morning at $38, valuing the company at a staggering $104 billion. about 90% of shares will be available only to the very wealthy. ordinary investors

thunderstorms from charlotte and atlanta down to miami. heating up across the plains. also stormy in the northern rockies and the dakotas. some gusty winds in the southwest. >> 97 in phoenix. 89 in

but this one kind of tops them all. >> oh, wow. a fisherman hooked a 1,360-pound kaluga sturgeon in a northeastern china river basin. enlisting some much-needed help, he turned this monster over to a breeding station. wow. it's a whale. >> shamu, what's up? it turned out to be a female carrying more than a million eggs. and that's good news since the kaluga is critically endangered. a big catch in many ways that can help the species. >> a million eggs. >> you got one and you know how that feels. >> a million eggs? >> can't get my mind around that. coming up next, the food flavor that could
