you to a group of young scientists who lived through the flint water crisis taking steps into their hands >> i'm phillip mena. >> i'm frances rivera. police are investigating a mass shooting at a supermarket in boulder, colorado, where ten people were killed it happened around 2:30 p.m. local time a suspect injured at the scene was in custody no word yet at a possible motive one of the victims was an 11 year member of the force >> my heart goes out to the victims of this incident and i'm grateful for the police officers that responded and i am so sorry about the loss of officer talley police officer's actions fell

nothing short of hero ifk. >> gadi schwartz. >> reporter: good morning, phillip and frances. a long day of investigating for officers going into that king sup percent for this second day after that deadly shooting yesterday. we understand there were 10 victims, one of them was a boulder police officer by the name of eric talley, a 51-year-old veteran of that force. he had been with the force for about 10, 11 years he was one of the first people to respond to that shooting and in the minutes that followed those initial reports say he was unfortunately one of those ten victims. we understand the gunman has been taken into custody. we are told the gunman was the only one injured in the firefight. we saw a man who was handcuffed not wearing pants, not wearing a

shirt led out of the store bleeding from his leg. we don't know conclusively because police have not said whether that man was their suspect but they have said the only person injured was the suspect. we're waiting for more confirmation today so far, no motive at all of what would caution a man to walk into a supermarket during an afternoon in boulder, colorado, and open fire. again, ten people dead and one of them a boulder police officer. we'll have much more throughout the day. >> heartbreaking story still developing thanks. president biden takes his relief tour to ohio today. it comes on 191th anniversary of the affordable care act being signed into law. tracie potts joins us. grappling with the migrant surge at the border. >> reporter: they are. we now know that there are more than 15,000 migrant children unaccompanied minors in u.s.

custody. nearly 5,000 of them at the border and some of them being held in very crowded detention facilities that were not designed for long-term holding take a look at these pictures provided by congressman henry quair. he says they were taken last weekend. customers and border patrol and the government are not denying or disputing that these pictures are authentic although they did not provide comment. they appear to show the situation right now at the border, which the white house says is key to focus on getting those kids out of border patrol custody and into the hands of health and human services. >> our alternative is to send children back on this tresh royce journey. that is not in our view the right choice to make we want to move these kids as quickly as possible through

these facilities and into the shelters where there is safe spacing and then move them into homes where there is safe spacing and we are concerned about the public health impact that's why we're putting in place a number of policies to expedite these processes. >> reporter: today officials from the white house, national security council, the state department are headed to mexico and guatemala to discuss what is causing this massive influx of migrants at the southern border and how to slow it down. >> becoming more and more of a priority thank you. more support is pouring in for loved ones ken jeong donated $10,000 to each of the five go fund me pages set up for the victims as the investigation continues, calls are being made to do more. here' blayne alexander. >> reporter: in city after city

their message to the asian-american people is clear, we stand with you. >> we are all part of the human race and we need to treat each other with love and kindness. >> reporter: it's been almost a week since a gunman stormed into three area spas killing eight people, six asian women. for the families shattered only adding to the hurt, that the shootings have not been labeled a hate crime as of now there is more of an having which is in the early stages. >> ruling a hate crime almost causes you to get inside the head of the defendant and figure out why they did something so you're going to be looking for any evidence that, for example, they had prior believes or ideologies that went towards hate, white supremacy, targeting of asians, targeting of women. >> korea's consulate general

says he will wait for investigators to release their findings. >> we are strongly condemning any kind of hate crime. >> a community grieving desperate to know more blayne alexander, nbc news, atlanta. more states rolling back restrictions but covid cases are going up more than 20 states are reporting a rise in the number of covid cases with three vaccines in the market, the country could have a fourth vaccine in its arsenal. astrazeneca is next to be approved for use in the u.s. nbc's tom costello has the details. >> reporter: with a diverse 32,000 u.s. participants in the u.s. trial, astrazeneca said the vaccine was 79% effective in preventing covid illness, 100% effective in preventing hospitals and deaths while already approved, some paused the rollout after a small number of people reported blood

clots though the company and european medical authorities say there is no evidence of a connection to the vaccine. >> there was clearly no difference in the occurrence of blood clots between the vaccinated group and the placebo arm. >> reporter: and no reports of blood clots in the u.s. trial which the fda will soon review. >> you can rest assured that the fda will put a great deal of scrutiny in every aspect of this data. >> reporter: because it's cheap, the astrazeneca vaccine is appealing for a global rollout the u.s. has agreed to buy 300 million doses when it is authorized possibly in early may joining pfizer, moderna and j&j's vaccines with more than enough to vaccinate every adult by may, the u.s. is poised to have a large vaccine surplus even as many countries don't have any. the white house is planning to lend millions of doses to mexico and canada and may need to tap

for booster shots. >> the more we get confidence in our increased supply the more fliltbility that gives us for different events down the road, whether it's vaccinating adolescents, whether it is sharing that supply with other countries. >> meanwhile, 69% of seniors 65 and older have received at least one shot. >> one other note here, there's been a lot of talk if you need a second vaccine next year or maybe a booster shot later this year, should you get the same vaccine as your original shot? researchers say it's not yet clear but i talked to people at oxford university who say if you go to a second vaccine provider for your next round, you may get even more protection than if you stick with the vaccine that you got originally so more research to be done on that back to you, frances. >> good to be able to look that far ahead, tom thank you. israel, voters are headed to the polls for the fourth time in

two years. unlike during the last three elections, prime minister benjamin netanyahu has not been able to use his close relationship with the trump administration in his campaign we're joined from tel aviv ross, tell us more about the state of this race before it's won there. >> reporter: phillip, frances, benjamin netanyahu made his close relationship with donald trump a center piece that's not an option this time he's pointing instead to israel's lightning fast covid rollout. his campaign slogan, back to live as far as restaurants, movie theaters reopened. netanyahu made the deal with pfizer's ceo to bring millions of vaccines to israel, but his opponent's just as determined to drive him out. thousands of them protested against him over the weekend millions expected to vote against him today. they point out netanyahu is actually on trial for corruption charges right now, charges he

denies so throughout the day we're going see that right wing block of parties that support netanyahu and that antinetanyahu coalition, parties to the left and the right, trying to turn their voters out guys, we will see tonight if either side has a majority in the israeli parliament. >> it's a much different world than the last time thank you, raf. now to another day of ncaa tournament action. another day of upsets and bracket busters. the day of second round games capped off with a trojan horse sixth ranked usc took a 19 point lead into the half and they did not look back. the trojans were led with 17 combined points from evan and isaiah mogley. another pac-12 team busted
