difference. "nightly news" begins now. good evening. brian has the night off. i'm leston holt. it's the technology empire built on the willingness of people around the world, 900 million active users at last count, to share the details of their lives. and finally today, after much hype, facebook is sharing its fortunes. it went public today in one of the most apted public offerings in years, opening on the nasdic under the symbol fb, but despite soaring expectations and liked among eager investors, facebook shares this afternoon closed barely above their opening close. it was a rough opening day in more ways than one for the giant, and maria is here with more. good evening. >> good evening, thank you so much. it's just eight years after computer hacker mark zuckerberg

sat in his dorm room in harvard university and created what is now knoep as facebook. he took the company public, and day one oza bit of a bumpy ride. facebook barely managed to meet its ipo price. >> let's do this. >> it started with 28-year-old ceo mark zuckerberg ceremonially ringing the opening bell after staying up all night with employees at the company's menlo park headquarters. but the first trade scheduled for 11:00 a.m. was delayed by overwhelming trading volume that also swamped sites like etrade. >> nasdaq had tested all week long, but obviously, it still overwhelmed the system. >> finally, at 11:30 -- >> now it is officially a public company available for everybody to by shares should they desire. >> the first trade at $42.05, up

nearly 11% from the ipo price. on facebook's website, this update from the ceo. mark zuckerberg listed a company on nasdaq, but the stock dropped quickly soon after, trading well below expectations and the volume continued to cause problems with communications. >> what went wrong today is when people put in buy orders and other people put in sell orders, they never got the word or confirmation on whether the order went through. >> they were working to deliver pending trade execution status messages from the facebook ipo. once those confirmations started coming in around 2:00 p.m., the stock started closing again, closing just 23 cents above the ipo price. what went wrong? many analysts believe it was overvalued from the get go. it is valued at $104 billion.

making it bigger than companies like mcdonald's or visa. carly was ceo of lucent when it went public in 1996, the largest ipo in history at that time. she said it's now up to facebook from here? >> can the company monetize the 900 million relations. >> now, let's not forget, with all of the noise around the deal and the sloppy trading, facebook was still able to raise $16 billion on a day that the mockt was weak and the down has din down. it's a tough time, so not as strong as expected, but a strong capital raise nonetheless. huge numbers. >> watching it play off, i'm left waondering who had the wore day, facebook or nasdaq? >> nasdaq. they fought to get the listing on facebook. they got it and then they were overwhelmed by the volume and the trouble executing today. a lot of people never even got

their confirmation reports. they thought they bought at $40. it was actually $42. >> it comes alt the end of another dismal day on wall street. the dow was down 73 point today. that's the longest losing streak since 1974. the nasdaq was down, just under 35 points, and the s & p 500 fell more than 9, wrapping up their worst weekly lossoffs the year. >> in north carolina, the jurs in the john edwards campaign corruption trial have gone home. they're rezul their deliberations on monday. every 17 days of testimony, most of it emotional, focusing on edwards' secret affair with rielle hunter and the anguish of his wife, elizabeth edwards. they deliberated for about five hours before the judge sent them home for the weekend. now to florida and the newly released documents, audio recordings, and photos in the

trayvon martin case. new images showing us what trayvon martin looked like just before the fatal shooting and what george zimmerman looked like afterwards. plus, we're hearing what some of the witnesses saw that night. kerry sanders reports now from sanford, florida. >> these are the last known images of trayvon martin, moments before his death. the 17-year-old captured on surveillance tape at a nearby 7-eleven, picking up skittles and an iced tea. until now, many pictures of the victim have shown him as a yo g youngster, but the day he died, he was 5'11", 158 pounds. the case now centers on what happened next. was neighborhood watch captain george zimmerman, pictured here after the shooting, aggressive or defensive? was the shooting with his cal tech 9 millimeter justified or second degree murder? at 5'7", zimmerman was four

inches shotter than martin but 42 pounds heavier. in the police photos, zimmerman is clearly bloodied and according to his doctor, likely suffered a broken nose. >> tell we what you heard or winlzed. >> we heard someone yelling outside. >> there are 22 witnesses, most of their police interviews recorded. >> i looked and didn't see anything. >> not one actually saw what or who initiated the fight. wince number six saw martin on top of zimmerman. >> the guy on top in the black hoodie was pretty much throwing down blees on the guy kind of mma style. >> one caller picked up this cry for help. >> so you think he's yelling help? >> yes. >> it's been unclear whose voice that was. martin's mother said it was her son, but when his father listened to the tape, an investigator writes, mr. martin clearly emotionally impacted by the recording, quietly responded, no.

>> in a recorded interview, zimmerman's father told blees the cry for help was from his son. >> that is absolutely positively george zimmerman. myself, my wife, family members, and friends, know that that is george zimmerman. there is no doubt who is yelling for help. >> in the 183 pages of documents, one lead detective writes the encounter between george zimmerman and trayvon martin was ultimately avoidable by zimmerman. if zimmerman had remained in his vehicle and awaited the arrival of law enforcement. the mountain of evidence released so far does not include the text messages from trayvon martin's phone nor does it include the police interrogation of accused murderer, george zimmerman. sdwr thanks, kerry. >> health news tonight and a sweeping new proposal aimed at america's baby boomers. the cdc wants all boomers to be tested for a dangerous viral

intection many don't know they have. hepatitis c. >> under the proposed cdc guidelines, those in their 40s, 50s, and 60s should get a hepatitis c test at least once. more than 3 million americans already have hepatitis c, transmitted by contaminated needles, blood transfusions prior to 1992, and possibly sexual contact, and 75% of those are baby boomers, born between 1945 and 1965. according to the cdc, 1en 30 boomers has been inficted with hepatitis c and most do not know it. the virus can cause serious liver ediseases. still, people can remain without symptoms for decades. cdc officials estimate that the new recommendations for testing could detect hundreds of thousands of new cases. the need for testing is becoming
