Nbcs mike taibbi has been gathering details for us and joins us from our los angeles newsroom with the latest. Mike . Reporter good evening, lester. While the investigation continues, the incident itself is over. A Police Spokesperson telling us there is no longer any danger to the public. Police say it happened around 11 30 a. M. Two Las Vegas MetroPolice Officers were sitting down to lunch at a pizza restaurant on the north side of town when two suspects, a man and a woman, walked in and shot them at pointblank range. A witness shouted this is the start of the revolution, and then both suspects left the restaurant, crossed the street to a Walmart Store and shot and killed a civilian they confronted by the entrance. Police say the two suspects then entered the store where they turned their guns on themselves in an apparent suicide pact. As the drama was unfolding, there was panic in the store said reporter elizabeth donatelli. One woman said she dropped to the floor when the shooter ran by her and texted her son i love you. Reporter the store was evacuated, employees bussed to a secure location where according to one twitter posting they will be evaluated for stress. A walmart statement called the shootings a senseless act of violence, adding that the store will remain closed during what is still an active investigation. So on what the sheriff called a truly tragic day, five dead, both officers, both with young families, dead tonight. Mike taibbi, thank you. Were following an unfolding situation tonight in karachi, pakistan, where gunmen stormed a terminal at the airport in that city. At least five people were killed, although some reports put the death toll at many more. A major fire was also reported. The police and Army Commandos were fighting the attackers.

Eight days after his release in that controversial Prisoner Exchange with the taliban, were learning much more about Sergeant Bowe bergdahls condition and how he was treated during his years of captivity. Nbcs Kristen Welker is at the white house with more on that. Kristen . Reporter good evening. Sergeant bergdahl is in good enough physical condition right now to return to the United States but they also say he is not ready emotionally or psychologically. And as he continues to recover, the debate over his release rages on here in washington. Recovering at a u. S. Military hospital in germany, Sergeant Bowe bergdahl is describing harsh treatment at the hands of his captors. U. S. Officials tell nbcs Jim Miklaszewski bergdahl tried to escape and when caught was confined to a small boxlike space. He was clearly treated more harshly at sometimes but wouldnt say if that rose to the level of torture. Officials also say he hasnt yet chosen to call his parents, despite the fact his doctors have said he can. Meanwhile, back at his hometown hailey, idaho, some say they are stunned by the backlash against bergdahl, amidst allegations he may be a deserter for walking off his base, something defense officials are investigating. Its been very shocking, i think, how vicious the attacks have been. Reporter the fbi says it is investigating reports of Death Threats against the bergdahl family. We are aware of the threats to the bergdahl family, and we are working with our local Law Enforcement partners to investigate. As always, we take these types of threats very seriously. Reporter in washington, there was more bipartisan anger that lawmakers werent notified before the five taliban detainees were released from guantanamo. Its hard to be comfortable when you really havent been briefed on the intricacies of carrying out this agreement. Reporter the republican chairman of the house op;bg Intelligence Committee says he believes at least three of the released taliban will ultimately return to the battlefield after they leave qatar in a year. We have made a serious, serious geopolitical mistake. Weve empowered the taliban. Reporter secretary of state john kerry said the United States is prepared to track the men and act if necessary and dismissed the notion that the prisoner swap might put u. S. Troops in afghanistan at increased risk. I just think thats a lot of baloney. Reporter secretary of defense chuck hagel will testify about bergdahl on capitol hill on wednesday, and Senior Administration officials head to the hill to brief all house members tomorrow night. Lester . All right, kristen, thank you. The driver of a tractortrailer truck involved in the deadly accident that also critically injured actor tracy morgan and two others was freed on bail today.

Kevin roper, 35, a truck driver for walmart did not see slow moving traffic ahead until it was too late. Thats an indication to me that he was either drowsy or asleep.

Reporter walmarts ceo saidy if its driver is to blame, the company will take full responsibility. Late this afternoon, morgans agent said he has been more responsive today, which is an incredibly encouraging sign, adding that morgan sustained a broken leg, femur, nose, and several broken ribs, and had surgery on his leg today.

In the southwest, a deepening crisis tonight involving thousands of children from Central America who have been crossing into this country alone.

Reporter the unaccompanied children are being bussed to the u. S. Border patrol station in nogales, arizona, after overflowing detention facilities in south texas. More than 700 children from the Central American countries of el salvador, honduras, and guatemala are housed together vq now in a converted warehouse where they are screened by authorities. With even more kids en route, federal officials are scrambling to provide enough portable toilets, cots, water, food and showers as the state supplies vaccines for children, some very young, whove been through a rough ordeal even after they were caught. Children who have not taken a bath in nine days. Theyre still wearing the same clothes. Reporter since last october, more than 47,000 unaccompanied [ children, mostly from central 0y america, have been apprehended trying to enter the u. S. Illegally. Just this morning, this group from el salvador, ages 9 to 18, was picked up by texas police after crossing the rio grande in search of their parents already here. This girl saying of their journey, we all took care of each other. The little ones we would send up front. They are part of a surge in Central American immigration that began a few years ago, as many fled the violence, poverty, and drug gangs there. We perceive that the journey is frightening, traumatizing and probably will scar them for the rest of their lives. Reporter last week president obama declared a humanitarian crisis and ordered fema to care for the children. Moving kids to arizona, though, further strained relations with governor jan brewer, whos still angry over federal authorities dropping off undocumented families at bus stations in tucson and phoenix recently. She blames the current surge on Border Security lapses. And here in nogales, Central American consular Officials Say they believe the children are being treated well, given the circumstances, as u. S. Officials try to get ahead of this borderc crisis that shows no sign of letting up. Lester . All right, mark potter, thank you. Severe weather surprised many people in colorado today. At least five tornadoes were reported. One person was injured when a tornado hit a country club in aurora. Weather channel meteorologist Kim Cunningham is tracking all this for us. Kim . Reporter and lester, i think the surprise was actually that it happened before lunch. o 3 c1 i mean, there was a forecast for isolated tornadoes for that area, but it came a little bit earlier than forecast, the first one happening right before lunch and a couple of hours after that. Now the good news for that area, there is no more threat of Severe Weather. We do have tornado watch still in effect, though, for eastern colorado. Denver pretty much in clear at this time. All the storms now heading towards it looks like kansas into nebraska, possibly seeing some stronger ones coming into northwestern kansas in the next couple of hours. But denver proper, a few showers, a few storms, but overall the Severe Weather should diminish here. Now, were expecting more storms later on tonight for western parts of kansas and also into nebraska. Tomorrow were clear. So everything looks good in colorado for tomorrow. Back to you. Kim cunningham from the weather channel, thanks. This was a highly unusual day at the vatican where pope francis prayed for peace with none other than the israeli and palestinian president s. Nbcs Anne Thompson is in rome tonight with that story for us. Anne . Reporter lester, this Prayer Service was rich in symbolism that pope francis hopes will reignite the peace process. It began with a warm embrace between israeli president shimon peres and mahmoud abbas, the president of the palestinian authority. Then with the pope and the leader of the Orthodox Christian church bartholomew, they went to a carefully choreographed service in the garden where they heard prayers from the jewish, muslim and christian faiths. Each leader spoke, the pope saying peace calls for more courage than war. Peres told the group even when peace seems distant, we must choose to bring it closer. And abbas parade for safety and stability in the region. Then they all exchanged a sign of peace. This was broadcast live all around the world because the pope hopes it is these pictures that will push the people of the holy land to ask their leaders to end this conflict. Lester .

Around the country, drug courts have become a popular alternative for dealing with nonviolent drug offenders, offering them the help they need and a second chance. It is not, however, a get out of jail free card, especially for those who come before one detroit area judge, whose passion and temperament has left some defendants shaking in their boots, and earned her a nickname that says it all. You dont get a social life. I know. Reporter shes the ironfisted judge known as scary mary. Im not allowing it. Thats it. Reporter do you remember the first time you heard the term scary mary . It actually was something i had heard from a prisoner who k had said to my secretary, oh, you work for scary mary. Reporter as a Circuit Court judge in suburban detroit, Mary Chrzanowski keeps everyone on their toes. Youre going to leave this courtroom now and get on it now. Reporter did you want to be known as a tough judge . Tqel yes. I take the law seriously. I take my job seriously. And i wanted to be respected as being serious. Youre always going to have an addiction to drugs. Reporter but judge scary marys real passion is drug court, a volunteer job that occasionally shows her compassionate side. But youre doing this without using, which is great. Reporter but more often has her doling out tough love like a drill sergeant. Dont appease me, because i dont appease real easy. I want them all to think that somebody cared enough to finally slap them upside the head and say wake up. Reporter this Innovative Program gives nonviolent drug offenders a final chance to stay out of jail.

I am not your friend. I am your judge. I really am so sorry. You dont want to hear sorry, but i am sorry. The whole concept of a drug court is a favor to help you, to teach you humility, to teach you respect. Reporter statistics show that drug court graduates have 9 40 better chance of staying clean than addicts who go the traditional prisonprobation route. And since she has been presiding over drug court, judge mary hopes she is motivation enough for them to stay clean. I started to recognize how important treatment is for some people. I dont want to put people in jail. I want to try to help them through their problems. You can watch much more of judge marys story tonight on dateline at 7 00 6 00 eastern time.
