that could do to a mother's head. jeanne moos, cnn, new york. >> thank you for starting your day with us. we've got so much more ahead here on "cnn saturday morning," which starts right now. good morning, everyone. i'm brianna keilar in cleveland. it is 7:00. thank you so much for joining us. we may know who, but of course we're struggling with why. an fbi profiler and a psychologist piece together what we know about alleged kidnapper ariel castro and what perhaps may have driven him to the heinous crimes that he is charged with committing. plus the texas explosion that was at first thought to be an accident, but new information there may tell us that a crime has been involved. we have the details about what investigators are uncovering. and later we are taking you live to space. an ammonia leak at the international space station is prompting a very urgent space walk. we'll tell you what is at risk

and how astronauts there are preparing. the cleveland man accused of holding three women'ative f atc almost a decade is held in a 9 by 9 foot cell. dna tests of ariel castro confirm he is the father of the 6-year-old girl born to kidnapping survivor amanda berry. meantime, the prosecutor handling the case says he plans to charge castro for, quote, each and every act of sexual violence that he carried out. castro also could face murder charges related to claims he starved and punched michelle knight to induce at least five miscarriages. and this morning, while relatives of berry and gina dejesus continue to celebrate their safe return, knight's family doesn't know where she is. the 32-year-old woman has been released from the hospital, but a family spokesman says police

won't tell them where she went. let's bring in cnn's pam brown. what happened here? do we know where she is? do we know why perhaps she may not or authorities may not want her in touch with her family? >> we don't know where she is right now, brianna. i spoke to the stepbrother of michelle knight, and he says that police knows where she is, and he said, we want police to tell us where she is. we don't know. we've been looking for her. he said michelle knight's mom barbara has been trying to make contact with her and hasn't spoken to her. she went to the hospital to see her. she's been trying to reach her after she's released and still no luck on that front. the stepbrother says the mom loves her, misses her, wants to see her, and hopes to get a call from michelle knight on mother's day, which is, of course, tomorrow. the grandmother went to the house of gina dejesus yesterday thinking michelle would go there after the hospital. she showed up with balloons. the grandmother thought she would probably be there and was disappointed to learn that

michelle wasn't there and still doesn't know where she is. here's what the grandmother had to say. >> we were told she had been released and that she was coming over here. so we wanted to come over here and show our support for her. we haven't seen her. plus gina's parents have been wanting to meet us. >> so barbara knight is the grandmother, and we know she is in cleveland still trying to make contact with her. >> the other thing we learned is that cleveland police brought off or sort of didn't reinforce having michelle knight's name on the fbi's missing persons list. is that right? was that maybe an oversight? is was that on purpose? do we know what happened? >> it's not an oversight according to cleveland police. basically, they're saying, they just followed protocol. according to their orders, a

name must be removed from the fbi missing persons database if a family member is not able to give a definitive answer if a person is missing. what's interesting here, brianna, is that the case still remained open with cleveland police, and, in fact, we have the missing persons report, and it shows police tried contacting family at least 12 times as early -- as recently as last november. but then last january, we noticed on this missing persons report, it says validated. so we're trying to find out, does that mean they did reach a family member and they did learn she was still missing? if so, why wasn't she put back on the missing persons database? we know that michelle knight's disappearance did not garner as much attention as the other two, gina dejesus and amanda berry. the family says they're upset to learn about this. michelle knight's brother saying we want to know more about this. we want to see the missing persons report. in west, texas, in other news we're following, that investigation into the

fertilizer plant explosion has taken a bit of a different turn. investigators say they're now launching a criminal probe into last month's fire and blast that left 14 people dead. they've made an arrest of one of the first responders to the tragedy for having materials used to make a pipe bomb. it's far from clear whether there is a link between the two. cnn's david mattingly is in west, texas, for us. david, do we know anything about this arrest? what can you tell us? >> one of the people involved with the emergency medical services at the time, responding to the explosion that rocked west, texas, several weeks ago. what we're being told, according to what happened in federal court on friday, he was arrested for possession of materials to make a bomb. authorities were tipped off to this by a resident of the area who was described as having unwittingly taken possession of these materials from bryce reed.

now, these materials included a small pipe, caps, a fuse, also some powder chemicals that are used to make a bomb. officials at this point are not saying if there's any connection between this arrest and the explosion at the plant. reed was a very high profile figure in the days after the explosion, speaking to cnn, giving a nationally televised interview talking about how upset everyone was in the community, how devastated everyone was by this disaster. he was also a very high profile, delivering a eulogy for one of the fallen firemen. at this point, authorities are not speculating on any link whatsoever between this arrest and that explosion, but very serious charges here. they could carry up to ten years in prison if he is convicted. >> obviously, very serious potential charges there, david.

do we have a sense of what caused the fire? are we any closer to learning the cause? >> reporter: we've got a couple of investigations going on now. state officials launching a new criminal investigation yesterday. they're saying they want to leave no stone unturned. in fact, the county sheriff also saying this is a matter of public confidence. they want to make sure that everyone knows that they're asking all the questions, that they're looking at every possible angle. as far as the investigation and the cause of the fire itself, we were hearing from state fire officials about that earlier in the week, saying they're going to have to push back a couple of weeks. they had originally expected to soon be able to determine what the cause of that was, but they're saying they're going to have to push that back a couple of weeks because they're saying they're going to continue to look into every possible cause. they were able to rule out several factors here, including natural causes and weather, things like that, but they have not been able to rule out the

possibility this was a deliberate act or caused by some sort of human factor. that investigation pushed back a couple of weeks. on top of that, we now have the criminal investigation by state and county officials. >> david mattingly for us in west, texas. thank you for that report. next hour we'll speak to the landlord of arrested first responder bryce reed. he'll be sharing with us some of the details about reed's past. you may be surprised by what we learn. and the white house is defending itself against accusations that it tried to cover up key details of last year's deadly assault on the u.s. diplomatic compound in benghazi, libya. ambassador chris stevens and three other americans died in that attack on september 11th. a source tells cnn that in the days following the assault, administration officials agreed to remove from government talking points an initial cia assessment that a group with links to al qaeda was involved in the attack. the house committee held hearings on the benghazi attack this week, and the e-mails have

been turned over to congress as well. republicans want them to be made available to the public. the white house, though, insists there has been no cover-up. >> the white house changed the intelligence community's assessment of what happened. did the white house tell the intelligence community to say that there were demonstrations? the underreported fact of all the revelations today is do the documents bear out what we've said all along? the answer is no. >> we call on the president to release these unclassified, interagency e-mails, so that the american people can see them. >> we've heard from the administration and also republican leaders there. so far, though, the cia is not commenting. in other story, the irs admits mistakes were made in the handling of tax requests from conservative groups. but a director for the service

denies the, quote, political bias, unquote, played a role. several tea party groups accuse the irs of discrimination when they face delays in requesting tax exempt status. the director said of the 300 groups singled out for review, 75 were picked because they had the words tea party or patriot in their name. on friday the white house called those actions by the irs, quote, inappropriate. at least one law maker says russia dropped the ball on the boston bombing suspect, the handling of the suspect, we should say. a law enforcement source tells cnn that moscow withheld key details about tamerlan tsarnaev, like texts he sent his mother telling her he wanted to join a militant group. a member of the house intelligence committee told "the wall street journal" that that intel could have changed everything. but sources tell the paper the u.s. probably would have withheld that information too. and let's head back to atlanta now for victor blackwell, telling us a little

bit about something going on a little farther away from earth, victor. the international space station, brianna. in about an hour, astronauts will start an emergency space walk to fix the ammonia leak on the iss. i think we have video of the ammonia leak. see the little specks at the bottom of the screen. that's the ammonia. in that environment, it falls like snow. cnn's john zarrella is covering this from miami. just how big of a problem is this leak, and is it a safety concern for the crew at the iss? >> reporter: no, it's not. first thing we have to say is the crew was never in any danger with this. it is not a safety issue for the crew. but it's certainly a critical system issue they want to get fixed. you don't want ammonia coolant leaking out of the space station. they've had a similar problem in this very same area not long ago, but they weren't able to actually identify where it was exactly coming from or to be

able to fix it. as you mentioned, they had been able to eyeball it this time, and they can see those tiny white flakes, which is ammonia, leaking from what they believe is around a pump area on the space station. what they decided to do was go out right away, very quickly get to the space walk. the reason they're doing it so quickly is because, once the ammonia leaks out from that area where it is, they won't be able to find it again because the pinprick hole, the size is so small. they want to be able to go out there and hopefully be able to identify it, find it. they may even replace a pump while they're out there, if it's determined that the leak is coming from that pump. so right now tom marshburn and chris cassidy, the two u.s. astronauts, are in the quest air lock. they're doing the prebreathing, cleansing their bodies of nitrogen so they can get out there, and in just about an hour from now, they should be

egressing the hatch there and beginning what is expected to be, victor, a 6 1/2 hour space walk to try to isolate, find the problem, and hopefully to fix it. victor? >> john zarrella for us in miami. following the commander chris hatchell on line. "vital day at the space station as chris and tom go out to fix the ammonia leak." the emergency spacewalk is scheduled for the next hour, 8:15 eastern. we'll bring that to you when it happens. and another amazing story. a courageous young woman's battle to live. she survived for more than two weeks in the rubble of a nine-story building that collapsed on top of her. this is in bangladesh. from her hospital bed, she is now describing what she did to survive. that's ahead. all stations come over to mission a for a final go. this is for real this time.

boston bombing suspect tamerlan tsarnaev is now buried in a rural cemetery between richmond and washington. officials and residents in caroline county, virginia, are asking why here? cnn's paula newton is in boston with more details on that. this is sort of almost, paula, maybe a random place for the bombing suspect to be. >> reporter: absolutely. i'm speaking to tamerlan tsarnaev's uncle. they tried everything. the problem was no cemetery, no community wanted to take him. what happened here is very strange in the sense that a woman by the name of martha miller, who is a christian, decided that this was not right and everyone deserves a burial.

she got together with what they're calling an interfaith coalition in her community in rural virginia, and they offered the plot. the uncle, who was desperate at this point to find a place to bury his nephew, said that he was very grateful that he could be buried there. as you say, brianna, it was inevitable. any place he was buried was going to cause some controversy. the sheriff in the community was very blunt. if i'd known this was going to happen, i would have done something to try to stop it. if i could undo it, i would. he said he had absolutely no prior notice. brianna, this entire situation has been a bit of a circus, and for the victims and the their families, it's not a welcome distraction. they have mixed feelings about how he was buried, where he was buried, but at the end of the day, it takes away energy, and it's too much of a distraction when they're still trying to recover. >> is anyone concerned about the fact there is a physical plot of

land where this many booing -- where the alleged bomber, where the boston bomber is buried. i know this has been a concern in other cases where we've seen terrorists and them having a physical burial plot, that there may be a concern this could cause attention, that people may show up and deface the area. has anyone raised that concern? >> reporter: many have raised that concern. of course, everyone is hoping it doesn't happen. the bottom line is the family of mr. tsarnaev have said, look, we are muslim. cremation is forbidden. we wanted the traditional muslim burial. i asked tamerlan's uncle about that as well, and he said, look, if anyone does that, what can i do? what can i say? but at this point we wanted this kind of burial. i think that many here in massachusetts, many here in the virginia community are hoping that he has now been laid to rest and everyone can move on from recovering from the terror attack and that hopefully many will forget where he's buried.

some have pointed out that adam lanza, the shooter in newtown, is buried somewhere and not much was made of where he was buried or how it happened. again, to try and move on with focusing on the victims and their recovery and the city's recovery and not focusing on the bombing suspect himself. >> paula newton on the phone for us. thank you, paula. meantime, rescuers searching through a crumbled building had almost given up hope. then they heard the cries of a woman. she was buried alive for more than two weeks. her incredible rescue next. capella university understands businesses are trying to come back from rough economic times. employees are being forced to do more with less. and the need for capable leaders is greater than ever. when you see these problems do you take a step back, or do you want to dive right in? with a degree in business from capella university, you'll have

23 minutes after the hour now. listen, with all of the tragedy that we're following in boston and cleveland and the factory in west, texas, this is a story about survival. this is a story about optimism, and it almost seems too incredible to believe. for more than two weeks, a young woman was buried alive in the rubble of a factory that had crumbled around her. this is in bangladesh. she had nothing to live on but biscuits and water and there wasn't much of that. cnn's mary snow is following her remarkable story. mary? >> reporter: victor, it's a rescue that no one expected. the woman who survived is a garment worker, a wife and mother. she was able to attract attention by moving a stick through a hole in the debris. when a rescue workers reached her, she said, please save me. her name is reshma, and her story is extraordinary. 16 days after a building collapse in bangladesh that

killed at least 1,000 people, rescuers who long gave up hope of finding any signs of life discovered her in the rubble. not only did she survive, but she is talking. the 19-year-old woman says she rationed two bottles of water, according to reports, and obtained the water and some dry food thrown into the debris by rescuers after the collapse. there was also an air pocket. cnn's dr. sanjay gupta says a lack of major injuries also helped save her life. >> no crushed bones or broken bones or deep gashes. that's important because the energy to heal those wounds can sometimes take away from your overall survival. >> reporter: the lack of major injuries has also been seen in other remarkable rescues, like the one after the 2011 earthquake in turkey when an 18-year-old man survived in the rubble of his crushed apartment complex for four days. in haiti, there were a number of rescues called miracles. this man survived in the rubble

of a hotel for 11 days. >> the body will do a lot to try and survive. it will literally start to digest itself. it's tough to think about, but your muscle, other sources of calories in the body, they all start to make themselves available. you hear about people who lose incredible amounts of weight in a situation like this. it's because the body will seek out energy anywhere it can find it. >> reporter: and there was the case in haiti of edwin muncie who was believed to have survived for nearly four weeks in the debris. >> is the medical doctors, i remember when i was down in haiti, they were calling them miracles. when you think miracle, you think this is one of the most rare things obviously that we've ever heard of. every time we hear about this in the medical community, it is a single, usually anecdotal story. they're very, very rare. >> reporter: the young woman reportedly told doctors she ran out of food and water two days before her rescue. the dark space where she was trapped was said to give her enough room to sit and stand, but not enough room to lie down.
