0 many years and it will continue in capable and familiar hands. for all of my gratitude that work behind the scenes that make a show that helps you and thanks to you for watching. your comments over the years have made me better, the good ones and the critical ones. i will miss you more than you know. until we meet again, i am ali velshi. have a great weekend. >> a look at the temperature stories. north korea may have two missiles loaded on launchers after a week of threats getting more and more intense. what the white house is doing as it keeps a close eye on this. a small town sheriff gunned down just steps from the courthouse. i am talking to his daughter in a cnn exclusive interview. does she think her dad was targeted because he is a law man? it symbolizes a city jail in need of serious reform. inside prison, an inmate fooling around with a gun and this is just the beginning. we'll take you inside. north korea is taking aggressive action putting missles in place for a possible launch. it may just be a test or is it something more? north korea's al lies and enemies are watching closely. elise is joining me from washington. how is the white house responding to north korea's latest moves? >> well, fred, they're really trying to dial back the rhetoric, tone things down, and you have been seeing this the last few days. john kerry, the state department spokesman saying this does not need to get any hotter. at the same time what the u.s. expects is that north krooe can awill take some kind of action, fred. the white house said it wouldn't be surprised if north korea launched those missiles. they're hoping that these action that they're expecting from north korea won't be so dramatic that they can't find a way back to the table with north korea and that's what secretary kerry will talk about when he goes to asia later this week. south korea, japan, china, talking about a diplomatic way forward, how can they entice north korea to stop these threats curve the nuclear program. >> chien is one of the few allies. what kind of reaction is coming from beijing or directive is coming from beijing. >> it is interesting. they have been kind of quiet. you have them moving stealth bombers and you really haven't heard anything from china. china is really concerned about the u.s. exerting its influence in asia over the last couple years but i think it reflects a growing frustration on the rt pa of the chinese. they're north korea's biggest economic and diplomatic backer and they really don't seem to have a lot of influence on north korea at this time. we understand there is little communication between north korea and china and i think there is a growing debate right now officials and experts are pointing to in china about whether it is time to abandon its unequivocal support for north korea that perhaps this unabashed support for north korea is ant thet call to its interesting. >> elise, thanks so much from washington. in texas now police are taking every threat seriously following the killings of two state prosecutors and the wife of one. someone called in a bomb threat the night before hundreds gathered for a funeral of mike mclelland and his wife cynthia. so far police arrested two men for threatening public officials. martin savage is in texas following the case. martin, are the men arrested being further investigated for any possible links to the murders? >> no, fred, according to authorities they say they have been taken into custody because of the threats they made. one did it over a telephone and the other over the internet. the charge is pretty serious, making a terrorist dl ic threat and currently being held in jail on a $1 million bond each and likely they could be there for a while. it shows you they take it very seriously here and obviously so. they have this three people, two official from this county murdered in the last two months. as for the investigation, it is pushing forward but so far no arrests directly tied to the murders have occurred. fredricka. >> and, martin, any more from officials whether they're looking at this spate of violence involving law enforcement officials, any connections being made directly between texas, colorado, and now west virginia? >> reporter: right. we do know at least in the cases of colorado and the shoot willing of prison chief and with the investigation going on here that the investigators in both states have communicated. it is not like they talk every day and isn't necessarily suggesting there is a link. it just suggests it is probably pretty smart police work that the two departments with these kind of murders on their hands dealing with officials would communicate. right now they have not drawn a direct link to any of those three that you outline. that said, the investigation here is sort of going in multiple directions. there are a lot of people working the case. have you local, state, and federal help as well. they're looking at the possibility of maybe it was white supremacist group involved because there is a prosecution going on in this region involving such a group. it could be that it is something to do with drug trafficking cartels. there is a lot of that going on in north texas or could be just somebody who acted on their own, that had a beef with the officials. they don't know. they aren't saying. quite frankly, authorities are very tight lipped on this, fredricka. >> thank you so much from kaufman county, texas. all right. time for some final four action right here in atlanta. four hours from now the first semifinal game of the ncaa tournament kicks off. number one seed louisville against ninth seed wichita state. live pictures of a huge free concert under way at centennial park just step as way from the georgia dome and in fact right outside the george dome where we find joe carter. joe, soon all of the people at the stage will be heading your way for the game this evening. louisville is a clear favorite, at least a sentimental favorite to win the final four and tug at america's heartstrings this week with kevin ware. so what is the feeling in terms of how these teams are getting themselves ready to really come out on top? >> in that first game as you said you have the number one overall seed in louisville. a lot of people feel like they could win the championship, the sentimental favorite because of kevin ware and some say the cinderella, that flew under the radar thanks to florida gulf coast university and here is wichita state, the shocker not so being showing because of how they got here beating teams like gonzaga and number two seeded ohio state and we have really seen a lot of these majors or small schools make their way into the final four over the last few years. you have george mason, vcu, butler and now it is time the feeling is to get over the hump and finally win a championship for these mid-majors or smaller cools and louisville, of course, vega says is the big favorite, the 10-point favorite. back in the final four. they have the great coach and the great potential nba flairs on the roster so in a sense it is david versus goliath in the first game just after 6:00 eastern time >> and second game michigan versus syracuse. all eyes i guess folks really want to see syracuse come out on top. >> i think a lot of people are speculating that this could be head coach jim's last hurrah at this. he has been at this for 37 years. he has won over 900 games with syracuse. they have that really suffocating zone defense. they make it boring for the viewer to watch because they don't allow the other people to score many points. they held indiana to 50 points and marquette to 39 points. there is 40 minutes in a college basketball game. syracuse definitely great defense and you have michigan, finally back to dominance in college basketball. remember, 20 years ago the fab five, the infamous time-out, the shorts, the attitude, the program took a dip for a while and now they're back. here is michigan. a lot of people looking at that game, the michigan-syracuse game as being really even and even battle between the two teams, very competitive, so it should be great, again, 6:09 the tip-off between louisville and wichita state and follows with michigan and syracuse. we're going to get into it. we'll go all access before we hit the games tonight. 3 p.m. eastern. we'll show you the emotion. we'll go into the pregame speeching and the victory celebrations, the tears when the teams lose. hosted by rachel nichols and hall of fame basketball player reggie miller, 3 p.m. eastern on cnn, so we'll see you, fredricka, in just a few minutes with that. >> that's right. less than -- just over 50 minutes away. thanks so much, joe carter, appreciate that. so what are the thousands upon thousands of people here in atlanta doing before and after the game? how about going to free sting or dave matthews band concerts, the party is only beginning. nischelle turner has details now. >> reporter: hey, there, fred. greeting from centennial park where me and a few thousand of my closest friends are here enjoying the big dance concert series. take a look at the crowd. everybody is out here having a really good time. it is a beautiful saturday. there is a lot of final four fans. there is a lot of just music fans. have you a big smile. having a good time. >> great time. >> i don't have to ask you who are you going to. >> the cuse, baby. this guy is going for syracuse today. a lot of people out here listening to great music. listen to who is in the lineup. flo rida going to be on stage, ludacris going to be on stage and muse will take the stage. they have the anthem that fits the final four and the music that gets you pumping. that will be a lot of if unto see and the biggest thing about the concert, three days of the biggest name in music free. yes, i said it, free. i will spell it f-r-e-e, free. tomorrow there will be more great music. sting, dave matthews band, grace potter, and centennial park will be the place to be. all of this is free. yeah, i see folks walking behind me. that's what happens when you do shots out here. they dance and they -- do you want to dance?
