tonight on "nightline," murder trail. eight suspects now under arrest for the shocking double murder of a florida couple. and as 15 children grieve, new evidence from the crime scene and a new warning from the sheriff. this is one very disturbing story. struck down. a pregnant woman's sore throat turns into a fight for her life and her baby's. a 6-year-old girl dies just days after feeling ill. swine flu is claiming victims around the world, but just how dangerous could it become? and moon struck. 40 years after the lunar landing we get to see that historic first step like never before.

so will the doubters finally accept that we really did land on the moon? captions paid for by abc, inc. good evening. exactly a week ago, a team of masked men entered large home in florida. within the space of four minutes, they'd murdered a husband and his wife. a couple who dedicated their lives to fostering children, many of whom are disabled. since then, seven men and a woman have been charged in connection with the murders and today authorities announced the recovery of the murder weapon and a safe that was likely the target. but while investigators have made sound program with their inquiries the sheriff says there remains something about this crime that when revealed will shock us all. jeffrey kofman sat down with him today.

>> they are still reeling from the news of the murders in cold blood. but tonight, friends and neighbors of byrd and melanie billings came together to pay their respects to the surviving family members of the couple that cared for nine adopted children. all disabled. investigators believe this was the get away vehicle. it was used they say to transport several guns including the murder weapon. and under that sheet, the safe stolen from the billings' home. the van belonged to this woman, pamela wiggins charged overnight. she has been released on bond but the seven main suspects are in custody, each facing two counts of murder. >> we believe that this concludes the major part of our investigation and in our opinion, this was a home invasion/robbery where the people stole a safe and we think it is as simple as that.

>> you're heading down now to our investigative session. >> well, maybe not so quite simple. david morgan says there's a lot more to this case, he just can't talk about it. i think you have used the word in the past a humdinger. is there a hum dinger you can't tell us? >> yes that is a true statement. >> this is a robbery/home invasion, but it's something much more? >> much, much more. >> is this a -- wouldn't believe what's really gone on here? >> that's true. if i was a scriptwriter i would write about this. when the case comes to trial, and the information becomes open to the public, how they managed to come together and the plan was formulated and all of those intricate things become a matter of public record i think everyone will be amazed. >> that is all the sheriff would say that on that topic.

>> these are the interview rooms right here. these are a couple that are exterior and this is a holding area. >> this is videotape at the billings home that allowed investigators to crack this case so quickly. within a day, police identified one of the vehicles. that led them to the suspects. the sheriff says he is not sure he'd even have a suspect today were it not for this video. are you convinced that these men knew that there was a surveillance system? >> yes. i believe that we did have an individual that stated that there was a surveillance system. >> which is what has investigators confused. how well organized was this? >> very well organized. they trained for 30 days for this operation to include the their -- to practice th assaults. again, the one gaming -- gaping hole in their plan, less than ten minutes on the billings compound from the time they entered until they left, a little over four minutes while in the house, the two front

doors on the eastside and the one rear door on the northside very precise, a great amount of precision, and again, the one gaping hole was the alarm system and the video system. that was not disabled. >> why do you think that happened? >> we believe -- and again this is one of the areas that we're not satisfied with that -- with the investigation at this point, that there may have been another participant that that was their job, was to disable that. because it's the only thing that fits. everything was precise and precision driven to that point. yet, you leave on an alarm system that captures on video the time you enter the compound and the time that you're in the house. and again, that just makes no sense. >> that is one of the loose ends that investigators still have to follow, but sheriff morgan believes a week after the murders the most important part of this investigation is done. >> we are confident as a law enforcement agency that the violent offenders, those that, again, the seven that entered the billings compound and did this horrible thing to this

family are incarcerated. i feel confident our community is safe. we're doing the peripheral things, we're working the concentric circles and moving out. so i think it's time to do that. >> pull back a bit? >> to pull back a bit and give the team a little bit of a rest. >> but there are larger questions about this case that the investigators may never be able to answer. the billings had nine adopted children at home with them. all disabled, five with down's syndrome. the perpetrators knew the billings were wealthy, but they also must have known about the children. do you believe that they set out to murder the billings? >> i can't speak to that issue, but i would say off hand, edon't -- i don't believe so. >> clearly any murder is a cold blooded act but to murder the parents of adopted, disabled children, that's something that elevates it to another level here. do you have any sense that the defendants comprehend that? >> no. but again, i've been subject to this many times.

we have people who are asocial, that are sociopaths that have no conscience. >> you mean they simply don't care? >> they care about themselves only. it is about me. it is about my own personal wants and needs. >> the sheriff says when all the details of the case are finally known, it may be well be remembered in the same breath as the murders committed by charles manson and his followers. when you look at the acts, can you understand it? >> no. i cannot understand it. i can tell you that the images will be with me for the rest of my life. >> byrd and melanie billings will be buried tomorrow. i'm jeffrey kofman for "nightline" in pensacola. >> our condolences to them and the children they leave behind. our thanks to jeffrey kofman. when we come back, a pregnant woman's personal battle against swine flu. and new worries about exactly how widespread this pandemic may be.

president barack obama today designated nearly $2 billion to fight the h1n1 swine flu. the emergency funds he said required to address critical needs. it's been four months now since the first diagnosis in mexico and while for in the initial alarm over a global pandemic has subsided, the reality is that people continue to die and everyone is at risk. as nick watt now reports. >> brian and aubrey were mauried in florida. aubrey is now 27 weeks pregnant, everything was going well. >> she got a little bit of a sore throat on the 28th of june. and then she started to get a bit of a fever the next day.

>> tonight, aubrey is in the hospital, fighting for her life. she has swine flu. aubrey a 27-year-old waitress is the third pregnant woman in florida to catch the virus. >> when they tell you, you know, your wife is the third, and the other two didn't make it, i mean, it's a bleak picture, you know what i mean? you wonder, you know? she's fighting, she's strong and she's stubborn. i told her this is one time to use her stubbornness. >> our interview was interrupted by a call from the hospital. >> hello? this is brian. >> aubrey was just taken out of the medically induced coma. doctors are trying to keep her alive at least another week. at 28 weeks, if necessary, an emergency cesarean to save her baby. >> all right. thank you. um, her lung collapsed. so they have to put a tube in. so they need me to -- yeah, they need me to get to the hospital.

>> swine flu -- >> the pandemic is imminent. >> rapidly evolving situation. >> we don't know how bad the pandemic flu will be. >> swine flu -- >> on june 11, the world health organization declared h1n1 a global pandemic. the first flu pandemic for 41 years. >> once a fully virus emerges, the further spread is unstoppable. >> theory 40 thousand -- nearly 40,000 americans have been diagnosed with swine flu, more than 200 have died already. it is going to get worse. >> there are many aspects of the u.s. system that is clearly not ready for a major biological catastrophic event. we actually don't have enough beds or surgeon capacity or mechanical ventilator, so we can

end up in a big problem in a hurry. >> back in march, 5-year-old edgar hernandez was apparently the first human infected. the virus has now spread from mexico to 120 countries. it's spreading in the summertime in the northern hemisphere which isn't supposed to happen. it's spreading because h1n1 is totally immune -- a totally new strain. no one has had it before, so no one has built up an immunity. >> every single contact of an infected person is likely to lead to transmission. >> here in london, khloe buckley, an otherwise healthy 6-year-old girl died two days after falling sick. initially, doctors said she just had strep throat. parents across britain panicked, khloe's school closed early for the summer vacation. come the fall, the temperature

will drop. humidity will rise and we'll be back huddled indoors, breathing on each other. >> then it will start to take off with a vengeance when you have the reassembly of kids to schools. >> britain and the u.s. right now have similar infection rates and britain is now expecting 100,000 new cases every day. come september. we are already being told to stay away from the doctor's office. we can now be diagnosed with swine flu over the internet. today in britain, the government launched a national pandemic flu service. they're trying to maintain calm, but clearly, preparing for trouble. the government estimates one in three people in britain will contract the virus. today, one police chief said that the threat from swine flu is worse than the threat from terrorism. a little bit alarmist perhaps, but some very level-headed economists are predicting economic chaos. the government expects 12% of

british workers will be off sick every day. those level headed economists predict a painful 3% drop in britain's gdp. the u.s. could take an even bigger hit. >> workers in other vital or critical infrastructure sectors, transportation, communication, manufacturing, so forth, a lot of people would be too sick to go to work. so we could have a very diminished capacity of our ability to sustain some of the vital functions. >> president obama has announced the u.s. will begin mass vaccination in october. >> i think our best hope, this is again for the u.s. and for the world, is that we'll be able to gear up our ability to manufacture vaccine very rapidly. but the need will greatly overwhelm the availability of the vaccine. >> h1n1 spreads like wildfire, but there is a silver lining.

it's not highly pathogenic. it's weak. a lot of people will probably get sick, that might create a lot of chaos, but unless the virus mutates, the death rate will not come close to say the spanish flu of 1918 that killed 50 million worldwide. >> we don't need to be alarmist about this. we're just say that we need to be in the situation where we're preparing for the worst and hoping for the best. >> this pandemic might be a wake-up call. a lesson in how to handle disease in the modern world. but for the individuals like the updikes, it will be traumatic and potentially tragic. >> i just miss having her around, you know? you know, she's everything i have. >> tonight, we hear that aubrey is stable, but critical. the doctor described this as a bad day. aubrey's chances of survival are fading. i'm nick watt for "nightline" in london. >> defending against a public

health crisis of global proportions. our thanks to nick watt. when we come back, as we celebrate the 40th anniversary of a giant step for mankind, the original moonwalk as you have never seen it before. ñññññññññññ hi, may i help you? yeah, i'm looking for car insurance that isn't going to break the bank. you're in the right place. only progressive gives you the option to name your price. here. a price gun? mm-hmm. so, i tell you what i want to pay. and we build a policy to fit your budget. that's cool. uh...

but i think i might need more help. (announcer) approximately two out of three people being treated for depression still have depression symptoms. (man) i'm on an antidepressant, but i'm still not where i want to be with my symptoms. (announcer) if your antidepressant alone isn't enough, talk to your doctor. one option your doctor may consider is adding abilify. abilify is fda-approved to treat depression in adults when added to an antidepressant. learn more about abilify. call your doctor if your depression worsens or if you have unusual changes in mood, behavior, or thoughts of suicide. antidepressants can increase these in children, teens and young adults. elderly dementia patients taking abilify have an increased risk of death or stroke. call your doctor if you have high fever, stiff muscles and confusion on abilify, as these may be signs of a life-threatening reaction. or uncontrollable muscle movements, as these could become permanent. high blood sugar has been reported with abilify and medicines like it. in some cases, extreme high blood sugar can lead to coma or death. other risks include dizziness upon standing,

seizures, impaired judgment or motor skills, or trouble swallowing. adding abilify has made a difference for me. if an antidepressant alone isn't enough, talk to your doctor about the risks and benefits of adding abilify. the risks and benefits osow yyí

re;ñ oah whoah whoa! honey honey honey honey honey! okay... i mean... you can't... this isn't a stove, alright? i mean... what if i just walked into the kitchen and started making a salad? - that'd be weird. - right? i mean, look, there's a technique. - okay... - ( strikes match ) wow. it's okay, everyone. - thanks, hon. - you're welcome. announcer: yep, it's that easy, - with kingsford match light. - ( match strikes ) 40 years ago today, apollo

11 launched from florida on course for an historic lunar landing, and an american triumph in the space race. 600 million people watched neil armstrong's first step on television, but to don sirsy -- to conspiracy theorists the picture alone wasn't enough, and as we see it again, there's new fodder for skeptics. and for david wright, it's "a sign of the time". >> the camera wasn't there to capture cortez or columbus. >> and we're getting the picture on the tv. >> but armstrong, the day he first set foot on a new world, everyone on this world held their breath and marvelled. >> that's one small step for man, one giant leap for mankind. >> the images were grainy and ghostly, but that didn't matter. this was live tv from the moon. amazing we got to see it at all.

the nasa tv engineer that day was just 28 years old. >> you get one shot at live coverage of what's occurring. you get one shot. you get it live that what's we did. it was live to the world 600 million people. >> at least one of those 600 million was disappointed. the westinghouse engineer who designed the lunar camera expected better. >> we know what it should look like. and this was not what we -- what we had seen in simulation. and i didn't know -- i knew that something bad had happened. >> the men of capry -- >> that's where the conspiracy theorists come in. >> there's only one small catch. it never happened. it's all a live. >> like the post watergate movie, capricorn 1 alleging that a tv broadcast from a mission to mars was just an elaborate hoax. the developments nasa announced today won't exactly put those

theorys to rest. today, nasa confirmed that all 45 of the original tapes of the moon landing were accidentally erased. tapes that they say were better quality because they came from the original feed from the moon, not what was recorded off the air. >> it's sad that -- i mean, the loss of those is a tremendous loss. because the resolution and the quality of that was superb. >> today, nasa also gave a sneak peek at its effort to remaster the best recordings that do exist. this contracted the hollywood company that cleaned up casablanca. >> here's looking at you, kid. >> the company that gave bambi a fresh lease on life. to have a crack at the moon pictures and see what they could do. >> our goal is to provide the best possible quality out of that video source, that can be done without altering the historical context in which it was done. >> the results are impressive.

the details a little clearer, the noise greatly reduced. one small improvement for posterity, but still, one giant leap of faith for conspiracy theorists. >> these theories and -- i wouldn't call them annoyances, i find them entertaining. i was there. i know when tv comes down to my tracking site, when i'm looking at the moon, there's nothing at that site that's producing it. there's no tape play back. it's ludicrous. >> perhaps if nasa had done a better job of keeping track of the originals they'd have an easier time convincing the doubters. the rest of us, well, we get a little nostalgia trip, a fresh glimpse of an era when tv had rabbit ears, but man walked on the moon. i'm david wright for "nightline" in washington. >> i remember it well. i was just 6 years old. our thanks to david wright. when we come back, breaking news. several are dead, many more injured as explosions tear through two indonesian hotels.
