christi paul. let's get started. recovery crews in west virginia now have the grim task of recovering the nine remaining bodies inside the upper big branch mine. two separate crews made their way inside the mine this morning and a team of federal investigators is arriving today to try to start to figure out what in the world caused that deadly explosion last week. some of the 29 men killed in the blast have been buried. president obama ordered u.s. flags in west virginia to be flown at half staff in honor of those miners. and west virginia's governor is asking people from all across the country to observe a moment of silence today at 3:30 p.m. eastern time. in about two hours, we'll find out whether nfl star ben roethlisberger will face charges in an alleged sexual assault. last month, a 20-year-old college student accused him of sexually assaulting her at a nightclub in millageville, georgia. "in session's" jean casarez joins us with all the latest. you've been following all the angles, making as many phone calls. what do you know about this? >> this all alleged to have happened in the early morning hours of march 5th. and ben roethlisberger was in georgia because he has a home near millageville, which is where this all is alleged to have happened. it's a small town, college town. he was seen in the local bars that night and had a female companion with him. witnesses say they went from one bar to the other. well, then what we know is in the early morning hours, this alleged female sexual assault victim went to a local downtown police officer and said i've been sexually assaulted. and she went to a hospital after that. she was subsequently released. then she went to the police or they came to her, a criminal complaint was filed by her and thus began a georgia bureau of investigation. this is a law enforcement investigation. they look at the facts. they interviewed countless witnesses. they started a defense investigation before charges were even filed. it went into the hands of the d.a. last week and we expect in just a couple of hours, richelle, the district attorney will announce if there are going to be charges in this case. >> jean, does part of the investigation, one would assume, means you talk to the accused. do you know whether or not that happened? >> yes. they have spoken with the accused. they have spoken with other countless witnesses. i think today at 2:00, they'll see how much they say. but she went to a hospital. that means a sexual assault kit was taken, where there can be forensics involved. what we do know is that roethlisberger did not submit any dna at all. he had ed garland as an attorney. by not submitting dna, might you say there was no dna to test on? could that be one issue right there? i can confirm with you also that he never did speak with his police. but that is common sense. he got a defense lawyer right away and that defense lawyer then took care of things for him and he did not give a statement himself. >> so the accuser did speak with police. when i say the accused, ben roethlisberger actually did not speak with police. >> yes, you are correct. >> this may be going out on a limb, jean, but does that also mean in a case like this, you or i wouldn't have to speak to police either? >> i think what this -- the lesson to be learned at this point is, get yourself an attorney and get yourself the best attorney you can and they began a defense investigation. they had an investigator that went out and interviewed witnesses at the very same time that the georgia bureau of investigation was doing it. they then had their results and they must have submitted them to police and investigators also at the same time. that's the moral of the story here. >> jean, thank you for the wrap-up and the look ahead. we'll know more at 2:00. thank you, richelle. well, leaders from 46 different countries are joining president obama in washington today kicking off a two-day nuclear security summit. they're going to discuss what president obama calls the biggest concern for the world and u.s. security. of course, that is keeping nuclear weapons out of the hands of terrorists and rogue nations like iran and north carolina. that's what the president says. this comes one week after president obama and russia's president agreed to cut the number of nuclear weapons in both countries by about one-third. the two-day summit is the biggest assembly of world leaders hosted by an american president since 1945. one of the main points of the nuclear summit making sure terrorists like osama bin laden don't get nuclear weapons. how big of a threat do you think the al qaeda leader is? we hit the streets to get your views on bin laden. >> i'm joe carter. and this is hln's views from the streets. osama bin laden. it's been nearly nine years since the september 11th attacks. how important is it that we still catch him? >> let me show you some video of osama bin laden. >> uh-oh. >> remember this guy? >> osama bin laden. >> yeah, the most notorious terrorist. >> he's an idiot. what can i tell you. his beard is too long and it's too gray. >> do we still need to capture this guy? is that important? >> yes. i think so. >> i say financially, no. i am just done with it. >> it's good if we can capture him but spending billions of dollars to capture him may not be worth it. i'd rather spend it on something useful. >> it's very important. you cut the head off the snake, then the rest of them know that we mean business. >> a hunt going on for so long. we need to finally put it to rest. do our power to bring him to justice. >> i'd like to catch him but, hey, i'm not worried about him. he's not part of my life. >> really would be more symbolic than anything else. i don't think it would matter too much. >> i don't think it's real important in terms of the war on terror that it would make up much safer. >> how important is osama bin laden to al qaeda? >> i feel like he's less important now because you have so many other cells in different countries. >> i don't think he's very important to al qaeda. >> i think he's a major influence to people that believe in him. >> do you finishing we do capture him we'll capture him alive? >> no. i don't think. >> i don't really think they would allow that, but i think that's the way that the government might want it to seem. >> i think he'll be captured dead or just be missing altogether. i don't think they're going to drag him out of a hole like you did hussein. >> killing him is not going to stop terrorism. >> i am joe carter. i'll see you on the street. president obama says intelligence suggests bin laden's associates are still trying to get materials to build a secret nuclear bomb. two people are in critical condition after a massive fire ripped through an apartment building in manhattan's chi chinatown. 30 firefighters were also injured in this fire. it was a seven-alarm fire. it broke out at about 10:15. it took hours for crews to get that fire under control. the fire spread to other buildings. a fire department spokesperson says three of the four buildings that caught fire are gone. still trying to figure out what caused the fire. a famous celebrity biographer claims she knows more about oprah winfrey than oprah knows about herself. why the author is refusing to divulge what she knows about the queen of talk's biological father. anti-government protesters in thailand carried their dead comrades through the streets of bangkok today. the redshirts, as these protesters are known, want the prime minister to resign. 21 people were killed this weekend in clashes with thai security forces. 17 of the dead are civilians. four are military personnel. more than 800 others were hurt. the country's election commission said today the ruling party must be dissolved for misuse of donations. at least 11 people were killed today when a landslide in the alps caused a train to derail in northern italy. five people are seriously injured and italian officials say the death toll could rise. mud from the landslide got into the train's cars and suffocated the passengers. we don't know how many people were actually on board. this is a small, local train. poland's president will be buried on saturday. lech kaczynski and 95 other people were killed in that plane crash on saturday. russian investigators say there were no technical problems with the soviet-made plane. they are suggesting human error caused the plane to go down during a landing attempt in dense fog in western russia. dozens of polish political, military and religious leaders were all on that plane that is owned by the polish government. only 14 bodies have been identified so far, including the president and his wife. kaczynski's body was returned to poland yesterday afternoon. you can see it there. americans with ties to poland packed churches in chicago and new york to remember poland's president and the others who were killed in that crash. outside of poland, chicago has the largest concentration of people of polish decent. >> all we can do is just stand before god, counting on his mercy. >> poles are known for their courage, for their survival skills, and they are also known for their freedom-loving aspirations. so poland will be fine. >> a massive crowd. look at that. flocked to the presidential palace in poland yesterday leaving all those candles. what a picture there. a week-long period of mourning there. the crash also killed the polish first lady and many top officials. it is still not clear what caused it but investigators have found the plane's flight data recorder. an american family put their adopted 7-year-old son on a plane to russia. that has touched off a major international conflict. top state officials will go to moscow to try to restore diplomatic relations and smooth things over. a tennessee woman adopted the boy from russia last year and renamed him justin. last week she said she simply had enough with him and sent him back. his adoptive grandmother said no one warned the family about the boy's violent tendencies. she says the boy is out of control. she claims he had a hit list of people he was targeting for attacks, including his adoptive mother. she also claims he tried to burn down the family home. the family says the russian orphanage where he lived never told them about his problems. the russian orphanage is outraged and his canceled all russian adoptons of children. american diplomats will try to get that reversed. in general, the question we're posing to you, not necessarily the way this woman handled it, but should you be able to return a child you have adopted?

that question prompted a number of nasa workers and contractors to hold a save space rally on the florida coast near kennedy space center. organizers claim the space agency's cutbacks could eliminate as many as 9,000 jobs in the area. >> we are very supportive of america's human space flight program and we want to retain leadership. we want to send a message all over the world that we want to continue our leadership by maintaining our own capability of putting astronauts into space. >> the agency could actually increase the number of its employees. nasa will be developing an entire new rocket technology, and that will increase its overall budget. we hear stories every day about people who become victims of identity theft. how do you protect yourself? clark howard tells us there's only one sure fire way to do it. >> want to give you a fair warning about a letter that may unfortunately show up in your mailbox. over 3 million to be exact -- 3.3 million people -- have had their information compromised. name, social security number, address and a bunch of other personal information was stolen from a student loan company's offices. now here's what you need to know. when you get that letter, they are going to offer you a credit monitoring service for free. credit monitoring, in my book, is a waste of your time. if you get one of these letters, the only true way for you to protect yourself is to lock down your credit, shut it down. and the way you do that is with a process that's little known but very easy to do called credit freeze. with a credit freeze, you are able to keep criminals even who have this information from opening accounts as if they are you. i'm clark howard. for more ways for you to protect your identity go to cnn.com/clarkhoward. >> what clark does so well, he'll teach you how to save more, spend less and avoid getting ripped off. catch him at noon eastern on saturday and sunday here on hln. a woman lost more than $200 and no idea where she left it. how it found its way to another state and right back to her. in about an hour and a half, the district attorney of mill edgeville, georgia is going to announce whether he's planning to file charges against nfl star ben roethlisberger. now how we got here is last month, a 20-year-old college student accused him of sexually assaulting her at a nightclub. this is actually the second time the pittsburgh steelers' quarterback has been accused of sexual misconduct. another woman is suing him saying he raped her in 2008. roethlisberger denies that allegation. let's talk about what could happen today. the d.a. has several options. b.j. bernstein is a defense attorney not connected to the roethlisberger case but is here to help us sort out everything. let's talk about what options the d.a. has. it's a little more complicated than people actually realize. >> his options are there could be an arrest warrant and ben is arrested. second choice is to actually present the case to a grand jury and let the grand jurors, which are 26 people from the community decide if there's probable cause to arrest or the third choice would be just to dismiss it outright. and based on how the prosecutor is doing this, which is by a press conference at 2:00 it was announced last week, i really doubt that he is sending it to a grand jury because that could actually influence a grand jury. and it sound like to me he's made a decision and we're going to hear that decision today. we haven't heard any rumors of ben being arrested. i think it's most likely a dismissal. >> how do you get to a dismissal or deciding whether or not to press charges without talking to the accused. what we're hearing is that it doesn't seem that ben roethlisberger ever gave any dna or ever talked to police. from the outside looking in, that seems like that's something that happens when you have rich attorneys. but you are telling me that's not always the case. >> remember, he hasn't even been arrested yet. and you have the right to remain silent. and that's a very important right. not because you are guilty and trying to get away from something. but because you want the police to focus on the state's evidence, which is what can they prove in this case. do they even have probable cause? and if this prosecutor says he's dismissing it, he is saying i don't even have enough to even arrest him, much less get a conviction down the road. and in so far as what i understand, apparently the officers briefly spoke to ben that evening so apparently they have something that he said. and that would have been the most recent thing -- time to whatever. and truthfully, no good lawyer and no one should really talk to the police without an attorney. that's the ideal. really, this is going to be based on what is the evidence or lack of evidence that the state has? >> okay. the charges and the allegations are sexual assault. without going into too much detail, b.j., people automatically assume that that means one specific thing. but sexual assault is a big term. >> yeah. and it's not actually a legal term. there's all different types of crimes in georgia. it could have been anything from as low as a misdemeanor such as simple battery or sexual battery, improper touching, to something far more serious such as rape or aggravated sodomy charges or something like that which would carry 25 years in prison. so that's why everybody getting excited about, well, what about the dna. where is the dna? most sexual assault cases you don't have dna evidence. it's certain types of sexual acts may not leave dna. and dna is really used in a case where you don't know the person involved as opposed to here where they are saying it was two people in a bar who were seen together that evening. the question really is what happened, if anything. >> okay. b.j., stick around. we certainly need your expertise on this. defense attorney b.j. bernstein. 2:00 is when we're going to have some answers. >> absolutely. moving on with the rest of the day's news. recovery crews in west virginia have the grim task of recovering the nine bodies inside the upper big branch mine. two separate crews made their way inside the mine this morning. a team of investigators is going to be arriving today to start to figure out what in the world caused that deadly explosion last week. some of the 29 men killed have already been buried. president obama ordered flags at federal facilities flown at half staff. the governor is asking people all across the country to observe a moment of silence today at 3:30 in the afternoon eastern. leaders from 46 different countries are joining president obama in washington today, kicking off a two-day nuclear security summit. they are going to discuss what president obama calls the biggest concern for the country and u.s. security. that is keeping nuclear weapons out of the hands of terrorists and rogue nations like iran a
