the court. good evening, parts of new england are staggering from the punishing blow of another blizzard. the fourth major snowstorm in three weeks. this one leaving as much as 20 inches of snow in some places. enough fell to make this the snowiest month on record in the city of boston where there is plenty to shovel just no good place to put it. snow driven by gusty winds caused whiteout conditions collapsed roofs and paralyzed travel. now the arctic cold dangerous below zero windchills extend from the midwest across much of the northeast. our team remains in place, miguel almaguer leads us off from boston. >> reporter: this is what many boston neighborhoods look like tonight. snow piles are on every street corner in this city.

to give you some perspective, this one is 15 20 feet in the air, at the level of streetlights. for now, the snow has finally stopped falling, this frigid cold is far from over. this was the triple threat nearly 100 million braced for, the blinding snow whipping winds and bitter cold. >> miserable. it's just getting really bold. getting depressing. >> much of new england blasted with whiteout conditions from sunrise to sundown. boston buried again. today 13 inches of powder on top of six feet that's fallen over the last month. the city getting more snow in three weeks than chicago has ever seen in an entire winter. >> this is storms of historic proportion. i know that people are frustrated people just want this to end. >> the region paralyzed in this blizzard blast. train, bus and ferry service all shut down. power knocked out to at least 6,000. at least four roofs crushed in

after relentless heavy snowfall. >> it's amazing this is even worse than the blizzard of '78 and i was here for that blizzard. >> reporter: along the coast, it was wicked winds doing the damage. the surging surf pounding threatening to flood marshfield massachusetts again. in plymouth, rare blasts of thunder snow. jim cantore there for the wild ride. >> we are in the full force of this blizzard no question about it. winds are gusting over 50 miles per hour we have -- we can't even see the water. >> reporter: similar conditions turn the roads deadly. this weekend, well over 100 accidents from buffalo to toledo. at least six killed including a pregnant mother on the ohio turnpike. tonight the snow has flowed but the arctic cold is just blasting in. in some regions it will feel like negative 25. >> insane more snow than i've ever seen. we're both transplants from

iowa and i've never sino like this. >> reporter: while they're bundling up for what could be record snow overnight. cities are scrambling to heat up the cleanup. this walk is extremely clean. snow mounds like this are common this one 10 15 feet high. come tomorrow morning this will be a solid block of ice. >> it's really remarkable miguel thanks very much. for more on what we can expect in the coming days let's bring in dylan dreyer who is in boston. dillon, good evening to you. >> good evening, lester the windchill is 10 degrees below zero it's only going to get colder through the night. by tomorrow morning, from the great lakes to the mid-atlantic up to new england, we are looking at windchills to be 15 to 25 degrees below zero and as we go into monday afternoon, it's never going to feel like it's above zero at all across new england. now, we've got another storm to talk about, this time around it's going to affect the midwest and eventually spread to the east into the carolinas, that's where we have our winter weather

advisories and winter storm warnings in effect. this could be a major ice event. that's where we will see a long duration ice storm, all throughout the day on monday we'll see snow move into washington, d.c. by tuesday morning, even up into new york city and possibly grazing southern new england as we go into tuesday afternoon, as for snowfall totals kentucky will be the hardest hit, that's where we could see a foot or more of snow. washington, d.c. 4 to 8 inches possible. maybe even another four inches across southeastern massachusetts, as for ice, a half inch of ice is possible from little rock to memphis, where that ice accumulates, we are looking at power outages likely, and dangerous root conditions throughout the entire day on monday. >> dylan, thanks. tonight the suspect is dead and officials are investigating what led him to open fire. first at a free speech event and later at a synagogue, the entire city of copenhagen remains on

high alert. that's where we get our report from keir simmons. hi keir. >> reporter: good evening, lester tonight a report of arrests, the detectives have not found evidence yet that their suspects worked with anyone else. candles on a cold night in denmark. for two more victims, of two more attacks in another european city. as detectives investigating the killings raided an internet cafe, searching for clues. this morning amid panic, they confronted the 22-year-old lone suspect and shot him dead. after he opened fire on them. his body lying in the streets. just over 12 hours earlier, the shooter had burst into a cafe firing 30 times. leaving more than 20 bullet holes in just the front window. there he left one dead and

wounded three police officers. inside an event was promoting free speech. >> i could hear the gunshots approaching, i could hear arabic shouts. >> reporter: the possible target one of the event promoters, lars hillings. last month, charlie hebdo was targeted. it printed similar cartoons. >> it's possible this individual was a copycat. >> you knew how to handle a weapon knew how to kill. we don't know if there are other people behind him. >> reporter: like in paris, the next target was copenhagen's jewish community. a 37-year-old guarding a bar mitzvah celebration was fatally shot. jews here say they will not be frightened. >> i'm born here and i will stay

here all of my life. >> our thoughts go to the whole of the jewish community today. they belong in zendenmark, they are a strong part of our community. >> reporter: jews have been murdered again on european soil. israel is your home, he told them. while in france outside the danish embassy in paris, another vigil was held today. their suspect -- there is no indication he travelled to iraq or syria to fight as a jihadist as the paris killers did. >> keir simmons, thank you. isis has released a chilling new video purportedly showing the beheading of 21 egyptian christians kidnapped in libya. it's the first time they've released such a video outside the territory it controls in syria and iraq. a masked fighter delivers a message threatening christian

populations making the war more religiously driven than political. the faa unveiled a proposal to unmanned commercial drones. dozens of industries have been pushing for permission to fly drones from movie studios to oil exploration firms. currently banned they're one step closer to getting permission to fly now. here's tom costello. >> it's the beginning of what may turn out to be something of a drone invasion from realtors hoping to sell million dollar properties to farmland surveys, tv tower inspections news gathering and movie chase scenes. the faa released its proposed rules for drones 55 pounds or lighter. they would only be permitted to fly during daylight hours. under 500 feet at 100 miles per hour or less and five miles away from airports. pilots would have to maintain constant visual contact with their drones and be required to

hold a new faa flight certificate. >> we have a responsibility to ensure that the national airspace system is safe for all users, as well as for people on the ground. >> already the nation's top aviation schools are teaching a new generation of pilots starting small -- >> we're about two miles south -- >> then getting military sized drones. >> when you're first learning how to fly this thing what is the biggest challenge? >> the biggest challenge is the positional awareness of the aircraft. whether it's flying toward you or away from you. >> the faa is also concerned about the number of close calls between drones and passenger planes. including this one last weekend at lax. >> one of those radio control helicopter things went right over the top of us at 4,000. >> over the top of you at 4,000? >> yes. >> just last month an unmanned drone crashed on to the white house lawn. today the unmanned aircraft industry said the faa's proposed rules make sense. >> we're going to keep them under 500 feet we're going to

keep them line of sight, we're going to keep them away from airports and essentially away from people. there's a lot of value that can be created with that alone, we think this is a good way to get started. >> all these proposed rules would apply to commercially flown drones. also to the president obama issue, he issued new rules how and when government agencies can use drones. >> tom costello in washington tonight. thanks. to a problem hitting home for many of the men and women who served our country. on any given night, nearly 50,000 vet rans find themselves homeless on the streets of america. now, the secretary of the va is taking a new proactive approach in dealing with the issue. tom brokaw has that story for us tonight from southern california. >> reporter: every two years an army of volunteers fan across greater los angeles. >> we're out doing the count tonight. >> to count the homeless. >> more than one in ten is a

veteran. los angeles long has had the largest population of homeless veterans in the country, even though many get a cool reception. it wasn't always that way. in 1888 300 acres of land were given to the federal government to be permanently maintained as a national home for volunteer 108diers. it was released to outside interests having nothing to do with the veterans. the land became some of the priciest and most coveted in california neighborhoods such as brentwood and westwood closed in. veterans like james carr see a raw deal. >> they don't care about any of this. they want to take this property and turn it into what they want. >> in 2011 a class action lawsuit was filed to force the government to honor the original deed. the vets had a powerful ally and attorney ron olson. >> when you have politicians

going around the country saying it's not right for these young men and women to go abroad and fight for their country, and then have to come home and fight for a roof over their head and yet these same politicians don't make something happen that's hypocrisy. >> reporter: olson and his coalition felt they had a slam dunk case the department of justice disagreed. arguing the agency was within its rights to release the land meant for the veterans. bobby shriver found many of his wealthy and powerful neighbors turned against him when he advocated housing homeless persons here. >> i thought, these are empty buildings, let's put them in empty buildings. who could be against that. >> reporter: just two weeks ago, a breakthrough. >> we're moving forward together designing a plan to end homelessness among veterans in los angeles county.

>> reporter: the new va secretary announced an agreement to settle the lawsuit. the two sides moving from adversaries to potential partners in a matter of weeks. veterans like robert malone formerly homeless himself saying it's about time. >> for crying out loud we're americans, let's help our guys since the minutemen, we've been protecting our country. let's protect them now. >> that was tom brokaw reporting from los angeles. when "nbc nightly news" continues on this sunday. how one state leads the way in so what about that stock? sure thing, right? actually, knowing the kind of risk that you're comfortable with i'd steer clear. really? really. straight talk. now based on your strategy i do have some other thoughts... multiplied by 13,000 financial advisors it's a big deal. and it's how edward jones makes sense of investing.

[announcer:] what if one stalk of broccoli could protect you from cancer? what if one push up could prevent heart disease? [man grunts] one wishful thinking, right? but there is one step you can take to help prevent another serious disease- pneumococcal pneumonia. one dose of the prevnar 13® vaccine can help protect you ... from pneumococcal pneumonia, an illness that can cause coughing, chest pain difficulty breathing and may even put you in the hospital. prevnar 13 ® is used in adults 50 and older to help prevent infections from 13 strains of the bacteria that cause pneumococcal pneumonia. you should not receive prevnar 13 ® if you've had a severe allergic reaction to the vaccine or its ingredients if you have a weakened immune system, you may have a lower response to the vaccine. common side effects were pain, redness, or swelling at the injection site. limited arm movement, fatigue, head ache muscle or joint pain less appetite, chills, or rash. even if you've already been vaccinated with another pneumonia vaccine, prevnar 13® may help provide additional protection. get this one done. ask your healthcare professional

about prevnar 13® today. ah! come on! let's hide in the attic. no. in the basement. why can't we just get in the running car? are you crazy? let's hide behind the chainsaws. smart. yeah. ok. if you're in a horror movie, you make poor decisions. it's what you do. this was a good idea. shhhh. be quiet. i'm being quiet. you're breathing on me! if you want to save fifteen percent or more on car insurance you switch to geico. it's what you do. head for the cemetery! we're back now with a growing concern over measles. the outbreak has spread to at least 18 states.

one corner of the country usually considered among the least healthy, has led the way in fighting measles, mumps and rubella. we get our report tonight from gabe gutierrez. >> reporter: despite 1-year-old's skylar thompson's protests her mom says she knew what she had to do. how important was it to bring her for these shots today? >> it's very important, i don't want her to be sick. >> reporter: here in mississippi, they have the nation's highest infant mortality rate. when it comes to vaccines for school aged children. the state leads the nation. and so far, not a single case of measles. >> i'm grateful really grateful that we have it and hope it can continue. >> reporter: last year 99.7% of kindergartners here were fully vaccinated. compare that to some other states pennsylvania just 85%, and california, 92%.

what's mississippi's secret? decades ago, the legislature passed a strict mandatory vaccination law for kids without some of the loopholes found in other states. here there are no exemptions for religious or philosophical reasons. >> if we don't vaccinate our children we stand the potential for public health crisis. >> reporter: not everyone believes the state is taking the best approach. mary jo perry is not against immunizations. she argues government mandates in mississippi go too far. >> we feel like parents should be able to do the research on vaccines and be able to discuss these things with their doctors, and they ought to have the liberty to have vaccine choice. >> reporter: she wants to make it easier for doctors to grant exceptions. >> this choice of not vaccinating your children actually affects the people around your child, not just your

child. >> reporter: she's a trooper. skylar's mom considers it an easy choice. >> i do whatever i have to do to make sure she's okay. >> reporter: to stop the measles outbreak, before it hits home. gabe gutierrez, nbc news, jackson, mississippi. when we come back in a moment some of the biggest names in comedy together for one night only. sometimes the present looked bright. sometimes romantic. there were tears in my eyes. and tears in my eyes. and so many little things that we learned were really the biggest things. through it all, we saved and had a retirement plan. and someone who listened and helped us along the way. because we always knew that someday the future would be the present. every someday needs a plan. talk with us about your retirement today. you know, just because your bladder is changing, it doesn't mean you have to. with tena,
