tennessee. some of the victims are related. police also found another crime scene linked to those deaths on the same street. a sixth victim was found across the state line in huntsville, alabama. police identified the suspect as jacob lee schafer, murder charges are pending. >> this is one of the worst crimes in lincoln county. it is a tremendous crime scene. we've never had a situation like this, but in a serious situation, once we determine exactly what it is, we back out and then start processing the scene from the outside in and that's what's taking place. >> well, so far we don't know the identity of the victims and don't know the cause of death or a motive. it is supposed to be a place for kidding to find a safe haven, in a industry grappling with a wave of violence but last night in chicago, a frightening reminder that no place is truly safe. two teens shot and wounded outside a church. aaron mendez of wgn joins me now from chicago with an update on that. >> reporter: good evening, don. interesting because the priest of this church st. sabina has been a longtime gun control advocate so this became a personal one for him last night when these two were shot on the front steps of st. sabina. >> so father michael pfleger was at a press conference. he has been extremely touched by this not in a good way. it has affected him coming out actually crying on camera. have you been able to talk to him about what his next move is? is he challenging police or investigators to try to do more when it comes to these types of crimes. >> reporter: they feeled calls last night and received ray number of tip, some they believe to be solid and had a message for the shooter. he was very furious and he pointed directly at these cameras and said you guys came to the wrong door and this is a personal fight for father pfleger because he lost his own adoptive son back in 1998 to stray gunfire so there's that personal thread too. >> talk to us about the other -- cnn has been investigating. i would imagine there are other news organizations in the area investigating all of these shootings and especially young people, teens being killed in chicago. i know the mayor addressed it recently. so did the police commissioner jody weist. what is going on there on the ground when it comes to investigating these shootings? >> reporter: you know, it's a huge problem. you know, they had 36 school-age children in chicago and this is just a tote aal up to june that were killed this year alone and they can't seem to get it under control and father pfleger is really taking the battle to the front lines and flying the american flag upside down like you do when there is a crisis outside the church to make a statement and say, hey, this is a major crisis in the city of chicago. we need to draw attention to it and it's beyond just, you know, enforcing it out on the streets. we need stronger gun control and pointing a finger at springfield and at washington right now. >> thanks, erin mendez of wgn in chicago with an update for us on the shooting from last night. we appreciate it, erin. getting word that father michael pfleger will join us at 10:00 p.m. eastern to talk about what happened right at his church. meantime, to pensacola, florida, a small safe haven from the deadly home invasion of byrd and melanie billings recovered buried in the backyard of pamela long wiggins, just one of the strange twists and turns in a baffling double killing. i should say a safe was found. susan candiotti takes a look at the lone woman suspect in the case. >> reporter: charged as an accessory after the fact to murder, pamela long wiggins smiles as the camera catches her under police escort. she's the only woman among seven men accused in connection with the shooting deaths of byrd and melinda billings. police say cameras that captured the suspects were also rolling inside the home. >> it's an incredible odd mix of people and an incredibly interesting and sad story. >> reporter: wiggins wasn't there but her minivan was, used as a getaway car. important evidence was found on her property. a safe allegedly stolen from the billings' home containing jewelry, passports and children's medication was buried in wiggins' back yard. a pile of bricks covering the spot. police say her husband was the one who tipped them off to the safe. a source involved in the investigation says wiggins kept it to himself until police found the couple on a 47-foot boat called "the classy lady." police say her husband cooperated. he is not charged. she is. she's a woman with at least six aliases including pamela link and pamela coco all of them apparently from former marriages. she's a real estate agent who also owns this waterfront home currently under foreclosure and well-known antique mall in the area. wiggins has ties to the suspected ringleader in the billings case, leonard patrick gonzalez jr. investigators say she rents a home to him. records show he witnessed one of her marriage certificates. how does a businesswoman wind up allegedly linked to the brutal murder of a couple that adopted and cared for more than a dozen special needs children at their spacious home? it's a crime that has pensacola's gulf coast reeling. >> all of us in this community are giving that second look now over the shoulder because here's a family that opened their home to children with special needs and because they had this casual relationship with the wrong people sadly they were targeted. >> reporter: wiggins remains free after posting a $10,000 bond. she is scheduled for a court date in a few weeks. in the thick of a still mysterious home invasion robbery investigation. susan candiotti, cnn, pensacola, florida. >> all right. the investigation into this crime has revealed some very unsavory characters with strange connections. escambia county sheriff david morgan joins us with the latest. they came out and said there are so many rumors about this

to break up a demonstration allegedly beating and arresting at least 40 people. witnesses say the demonstrators were hauled away in unmarked cars including a human rights lawyer. the crackdown came as ralliers and a powerful cleric called for the release of prisoners arrested last month during the fallout. they believe more than 2,000 people are still behind bars after the highly contested vote that gave mahmoud ahmadinejad a landslide victory. searchers in jakarta discovered a ninth body while sifting through the damage at two bombed hotels. here's what we know, surveillance video from the marriott shows a man culling a suitcase before a blinding blast you see right there. moments later another bomb rips through part of the ritz carlton. there's no claim of responsibility but suspicions are rising that the blasts were masterminded by a militant malaysian fugitive. he was a consummate journalist. veteran newsman walter cronkite died last night after a long illness. he was 92 years old. for decades he was the face of cbs news. he wasn't an old-school newsman, he was the cool and tonight former colleagues are remembering him. >> good evening, from the cbs news control center in new york, this is walter cronkite reporting. >> in the day when we were kids and starting under walter, walter embodied kind of the best of everything and the best you would aspire to. there were three networks at that point and walter was the most important man. you lived and died by what he said, how he wanted pieces to be told. you were answerable to walter when walter picked up the phone. you were scared to death. but on the other hand, there was a core value in what we did and, you know, it was a time when one voice mattered. >> from dallas, texas, the flash apparently official, president kennedy died at 1 p.m. central standard time. :00 eastern standard time. some 38 minutes ago. >> i remember that moment where he took off his glasses and he looked at the clock and he said that president kennedy has died, and i -- you know, that was one of earliest moments that you i can remember that i wanted to pursue a career in news and watched walter all through the days of the apollo space program and i remember him saying on july 20th, 1969 that man has landed on the moon. >> the eagle has landed. >> oh, boy. >> thank you. >> whew. oh, boy. >> we're going to be busy for a minute. >> i'm speechless. >> to say he was the most trusted man in america is an understatement. at that time anything that bad happened the world turned to him not only for the news but reassurance and he was -- he was not just an icon but he was, you know, almost like a member of your family. and to think that he is gone now is just such a sad occasion. >> he was the consummate television newsman. he had all the credentials to be a writer, an editor, a broadcast er. there was only one walter cronkite and there may never be another one. being friends with walter cronkite was about as high as you could rise in our business. to be his colleague and his friend was a double blessing. >> we'll have more reaction to the death of walter cronkite throughout the evening coming up in the

florida. police made eight arrests within days. now they are moving slowly and deliberately to ensure they don't jeopardize the prosecution of this case. escambia county sheriff david morgan has been the most visible voice of this investigation. he joins us tonight from pensacola, florida. thank you, sir, for joining us tonight. real quickly, i have to ask you, you know, there are so many -- you guys came out. there were so many rumors floating around about this case. why did you feel the need to hold a press conference to talk point rumors? >> well, because twopole, number one, to ex-pain a little bit about the procedure that we go through because we're trying to be as transparent and open as possible with the public and to be very frank with you, we did this for you, for the media. your assistant in this case has been pivotal and invaluable and i -- i as a sheriff and also the state attorney was very concerned that we come with a full disclosure to the press because you folks have just been there at a moment's notice when we needed you and so we wanted to confirm from again a state authority and not a civilian or excuse me a civil lawyer that, yes, in fact, this is what we have found in the safe. these are the documents recovered and those sorts of things. >> can you -- what did you find in the safe? you said it was prescription medication for the kids. >> for the children. we have some documents. there are some adoption papers and passports and there were heirloom jewelry in the safe. as we stated at that press conference, we knew from early on actually from the inception of this case after getting with the family and doing our first inventory of this house, we knew the contents of the safe but that's information you withhole as you bring people in for questioning. that's some of the things you use in leverage in the interviews to identify persons of interest versus suspects. >> real quickly because i want to get to a lot of things. nothing in that safe would lead most people to think why these people would be murdered. i mean there was nothing that valuable in the safe. there wasn't tons of cash or anything like that. >> that is correct. that is correct, sir. >> tell us about this woman. less a woman that has some involvement recently arrested. she was one of the owners of a van and that -- was this the red van we saw first or a second van we're talking about? >> there is a small maroon minivan that we have taken again as evidence. it's still currently being processed. her van was used for the transport of the safe and we believe the weapons. so, again, her involvement continues to come to the forefront on this and the public has sent us some e-mails and phone calls about the concern of her involvement and the charges that she had. i want to let everyone know that at no point in time do we stop this investigation and at no point in time will we continue to add charges to those when the evidence develops. >> sheriff, what about this unnamed teenager? >> no, sir, we don't -- we have not identified any ages of any individuals. i'm sorry. do you peen one of the seven? >> was there an unnamed teenager in all of this and what's the role that she has? >> no, sir. there's -- i'm unaware of that. >> i'm sorry. someone was talking to me. say again. i could not hear you. >> yes, sir, i'm unaware of that. we have some persons of interest we're still looking at but we have not released nor identified any teenagers in that mix. now we have a teenager in custody. >> go ahead. >> one of the original seven. >> one of the original seven. i just want to clear that up. i thought that was someone new -- we've been talking about a lot of rumors and wanted to get that cleared up, as well. let's talk about motive. everyone is trying to figure out motive. you guys know the motive, i'm sure. >> we do, sir. and, again, there is more than one motive. and, again, because we're in the game of high stakes poker at this point, the defense attorneys are coming on and interviewing their clients. we're being very, very careful in every move that we make to coordinate this with the state attorney's office to ensure that information that is released is released at the earliest opportunity but don't step forward and do a full disclosure which -- understand something, this is both for protection of the family for an embarrassment factor but the protection of the people under arrest and their rights. there are rules to the criminal justice system that we must all follow and i'm going to ensure that folks that are currently under arrest that we don't violate their civil rights. >> hey, listen, i'm up against -- i have a time issue here. when can we expect to hear something about motive? when might you say something? >> again, sir, we'll have to consult with the state attorney's office. i wouldn't expect anything until next week. >> escambia county sheriff david morgan, mr. morgan, i've seen you around the clock so i know you have been very busy. thanks for taking time for us on cnn. let's talk about nelson mandela. when mandela has a birthday party, everybody that's anybody shows up. we're taking

musicians paying homage honoring all the inspiration that nelson mandela has brought to our lives. spread around the world. still have them around and inspire us to continue to do good and support the less fortunate and the youth. >> you met him back in 2004. did you play for him in a concert? did you meet him then? >> we met -- i met nelson mandela in 2005 in south africa. went to his home and we did a concert, 40,000 people for the people in soweto. a free concert we did there. it was beautiful and he is just a great inspiration. >> tell us, did he inspire in my name by you and fergie? >> fergie wasn't on in my fame but it was me and apple and nelson mandela inspired it and mary ma keechlt iba, both in south africa and he's inspired a lot of our songs, union we did with sting was inspired by nelson mandela. filmed it in south africa and the new song on the end, called one tribe was inspired by nelson pan della, as well. >> i like that song. tell me about the pea pod foundation which again i'm sure was inspired in part by nelson mandela, as well. >> the pea pod foundation was started by the black-eyed peas back in 1998. one of our members, apple, was born and raised in the philippines and he was adopted and brought to america at 14. he met me and we started the black-eyed peas. when we became successful, we felt the strong urge to give back to kids orphans and foster kids and kids in inner cities and provide them the same tools that excelled our dreams, music, journalism, acting, dancing, editing, producing, directing and writing. so we built our first peapod academy in watts and equipped them with tools, high-definition camera. >> i can tell you, it's exactly part of the
