towards the back here of this area. like i said, police haven't confirmed what happened here yet. no word on suspects. no word on victims. but we have talked to a few witnesses who say they heard some gunshots. take a listen. >> i heard a bang, so i went out my door and i heard three or four more gunshots, and somebody jumped overred the fence and when i came out there was cops and police everywhere, the fire truck was here, the k9's. and i guess they're still looking for the individual. >> reporter: police still on scene here in lowell on pine hill street. still an active investigation. as soon as we get information we'll make sure to bring it right to you. >> anchor: thanks. also breaking, officials say north korea has launched a long-range rocket. north korea says that rocket is only carrying a satellite. the countryes it plans to launch more satellite. this launch comes a month after north korea claimed that it

the u.s. says it will investigate what happened. canton. a second person killed after getting hit by a fall branch, thoad. >> anchor: that accident happening just hours after this little girl, just 6 years old, was hit and killed by a fall limb during the storm. and tonight that community is searching for answers. >> anchor: police are warning people about the danger from above. the night team's killry o'hara in canton. >> reporter: two freak accidents within hours have many in this community asking why and police warning everyone to watch out. >> last night obviously everybody knew why we were grieving, for the young child in our community that we lost. we had another tragic accident. >> reporter: two tragic accidents in 24 hours. canton residents all mourning

off the loss of 6-year-old came can see kaylee, shocked to learn there was another accident, this time a 48-year-old married father of three lost his life. >> the tree limb was approximately 40 to 50 feet above him, directly above him. he did not hear and it had no time to react, and it struck him on the head, causing obviously very traumatic injuries. >> awful, just absolutely horrendous, the poor guy went out to clean up a little bit. >> reporter: neighbors say the aftermath of this storm has been dangerous. >> the branches are falling every 15 minutes. >> reporter: town officials devastated by what happened. >> it difficult to understand how and why these things happen, it's so random and coincidental. it's hard to figure out. and i don't know that we will. >> reporter: police are withholding the name of that father of three, all they'll say is that he's a beloved member of the community. they are asking to you pray for

that little girl. >> anchor: speaking of the snow and weather, now turning to the forecast, we're tracking more winter weather that could be heading our way, as the snow continues to melt. we could be dealt with another snow situation here, bri. what do we have in store this week? >> as we head through the next few days a good shot at snow monday tuesday, but also again wednesday and thursday, this is an unsettled pattern we're getting into. the cold air is setting in for us after tomorrow, so here we go with the timeline, the storm system that forms to the south of us near the north carolina coast and then it comes up the coastline through the day tomorrow, and in the wee hours of monday morning. now, this storm system in and of itself is well off shore, but it is a big storm system, and so it's throwing some of its snow shield in our direction. we also have very gusty winds that will be with us, and cold wind that are coming over relatively warm ocean waters, which could give us some ocean effect enhancement with that snow expected on monday.

and then we continue that with a second system on tuesday, and a third one on wednesday. so here's what we know at this point, breaking it down in bullet points for you. it is come politicked with those three systems i just mentioned, on and off snow showers for the better part of next week with that steadiest snow on monday and also the strong northeasterly winds, leading to possible coastal concerns. a winter storm watch has been issued for the south shore, plymouth county, cape and islands for all day monday. so how much snow are we expecting? we'll break it down in a few minutes. >> anchor: it may be cold outside, but things are heating up in new hampshire ahead of the primary. candidates are throwing punches at their oh opponents, it was a war of word on the debate stage, some candidates making a strong impression with just days before voters take to the polls. from the g.o.p. debate stage to the final push for democrats, 7 news has you covered. dan hausle with more on the republican debate.

the frontrunner is trying to stay at the top of the pack. you found the governors are trying to catch up with them, knock them off. and so you had had john kasich trying to do it by being the nice guy. you had had chris christie trying to knock off marco rubio. and jeb bush trying to do it by taking on donald trump. >> when you've never been responsible for that in your entire life. >> reporter: debate watchers looking for fireworks got them. >> this notion that barack obama doesn't know what he's doing is just not true. he knows exactly what he's doing. >> reporter: new jersey governor christie and senator rubio tangle over leadership and whether rubio ran from his own immigration reforms. >> i think the experience is not just what you did but how it worked out, new jersey has been downgraded nine times. >> that's what washington d.c. does, the drive by with incomplete information and the

mem ridessed 25-second speech that is actually what his advisors gave him. >> reporter: bush took on trump overle nebl domain and how trump used it for a private casino project. >> how tough is it to take property from an elderly woman? >> let me talk. >> reporter: kasich tried to be the nice guy. >> after being here, every one of my 100 town hall meetings in new hampshire were a lot more fun than what i saw here today, were so much more positive. >> reporter: the debate got off to a rocky start when ben carson was left in the wings, when ted cruz staffers counted him out. when i wasn't introduced number two as was the plan, i thought maybe he thought i already had dropped out. >> reporter: cruz apologized to carson and generally tried to stay out of the candidate crossfire. >> senator cruz, you said mr. trump doesn't have the temperament to be commander in chief. do you stand by those words? >> i think that is an assessment the voters will make. >> reporter: trump found that unpresidential.

>> if you notice, he didn't answer your question, that's what's going to happen with our enemies. we're going to win with trump, we're going to win. >> reporter: trump reminded us he thinks he only lost in iowa because ted cruz stole votes from ben carson the governor has their voices heard tonight, the question is how are the voters listening and will it make a difference. ben carson's message was simply i'm still here. we're live at the republican debate, dan hausle. >> anchor: another debate in the books, but will it impact tuesday's primary? andy hiller has his take on tonight's bin winners and losers >> reporter: there were seven republicans on the stage, but this was the 3d debate. the desperate demolition derby. and when all the collisions were finished a few looked ready to rumble some more, but others were totaled. drp donald trump was the biggest winner. you like the donald, you got

him, a lot of him. he may have even increased his support, thanks to a strong defense of his temperament and the harshest criticism of president obama. and another winner, chris christie, he needed a powerful debate performance to turn his campaign around and i think he got it. he's always loud, but tonight he was more, and found his voice. he was tough, aggressive, clear and compelling. you all know this. there were some big losers too. given the stakes, there had to be. the biggest loser was marco rubio. this was his worst debate. he didn't sound or look confident. he repeated himself and when he was directly attacked by chris christie, he withered. ted cruz lost, too, given a chance to challenge trump's - fitness for the white house and personal makeup, he stood down. and he could only aapologize to ben carson, after suggesting wrongly that carson was quitting the race after iowa. if you have a picture of all the republicans who debated tonight,

save it. because i don't think they'll be together again. new hampshire voters are about to do what they always do, turbo charge some candidates on the road to the white house and leave others as road kill. live in new hampshire, i'm andy hiller. and that's my instinct. >> anchor: the republicans wrapped up their night to the debate stage, bernie sanders is getting ready to take center stage, you're looking at the "saturday night live" set, the democratic candidate hosting right after 7 news at 11. meanwhile, hillary clinton focusing on her primary push facing an uphill battle in new hampshire. and getting a little help from a few familiar faces. to more on how the democrats are spending their final days in the granite state, byron barnett is live in portsmouth tonight. >> reporter: the two democratic candidates of course are battling very hard. bernie sanders trying to hang onto his lead, hillary clinton

today she brought in some heavy hitters for help, including some from massachusetts. >> that's why we want hillary clinton as our president. >> reporter: minnesota senator al franken with hillary clinton, trying to keep her supporters fired up and ready to go, as primary day draws near. >> i hope you will believe that we can wage and win the fight for the future, because i sure do! and i need your help on tuesday. >> reporter: clinton was joined by former secretary of state madeline albright who spoke to women without mincing words. >> just remember, there's a special place in hell for women who don't help each other. >> reporter: clinton went door to door in manchester, campaigning for votes, and she stopped in at a diner where she chatted with voters one on one. clinton also got help from across the border. >> you can make the difference in this election. >> reporter: a delegation of massachusetts elected officials came north to canvas for her. >> we have to be here to fight, because this is going to decide who the most powerful person in

america and the world is going to be, and hillary clinton is the best prepared. >> because hillary should be our next president, i mean hands down, there's no question for me. >> reporter: and clinton's democratic rival, bernie sanders, still leading in the polls, focused on his base which includes young voters by campaigning at franklin pierce college. >> if we can win here in new hampshire, the eyes of the world will know that this country is about to move in a new direction. >> reporter: in just a few minutes you'll be able to see bernie sanders again, he will be appearing on "saturday night live," later on tonight. i'll byron barnett, 7 news night feel. >> anchor: now on just one station we've seen a few days of swings in the numbers. >> anchor: but things are starting to settle down a built in our exclusive 7 news u. mass lowell poll. let's take a look at the numbers

right now. bernie sanders stays steady at 55%. hillary clinton gained a point. she has 41%. undecideds remain at 4%. and take a look now at our tracking poll, you can see bernie has stopped his downward trend. hilly is still ticking upward but tat a slower pace. >> anchor: here's a look at the republicans, donald trump up went up to 35%, marco rubio lost a point. ted cruz also lost a point. he has 13. jeb bush and john kasich both 10. the other republicans, chris christie, downone to 4%. ben carson also down one with 3%. and carly fiorina at 3% as well. undecided up one at 9. the tracking poll here, donald

trump remains at the top, but he all the stopped dropping, so he has actually picked up a point there. you can see a slight uptick there. it gets crowded. marco rubio, ted cruz, both lost a point while john kasich and jeb bush both gained two points there. our tracking poll continues right up to the new hampshire primary. we'll have the latest results for you tomorrow morning, right here on 7 news today in new england, that starts at 7:30. >> anchor: still ahead, a rush to the rescue in north andover, a deadly fire that could have been much worse if it wasn't for one man's quick thinking. >> anchor: and a deadly discovery, police investigating a body found in the heart of the back bay. alright guys. i want to show you some cutting edge technology. this is a vhs tape. push that tape in and hit play. this is a flip phone. have you seen these before? it's called a compact disc. oh. looks like we're getting a facsimile. what year is it to you?

it's old. you'd rather use newer technology? definitely. well, i've got something to show you. this is the 2016 chevy volt. it uses extended range electric technology. the prius hybrid uses battery technology developed 15 years ago. chevy expects volt drivers to get over a thousand miles between fill ups. it's got every technology there is. the prius actually belongs on the table. now it's new hampshire's turn, see who we choose in this dangerous time. one man stands above. he's not flashy, not rude... he's steady, he's tested and proven. he's a president, which is what we need to make us strong and safe again. for america, jeb bush.

>> anchor: a son rushes to his parents' rescue when they get trapped inside their burning home in north andover. but not everyone inside made it

>> a lot of sun that we saw today and that's the case again tomorrow. current temperature 31 in boston. 25 in worcester. 23 in norwood. our temperatures will not plummet overnight tonight, and that's because we have a southwesterly flow right now that is going to usher in some milder air for tomorrow. so not as cold tomorrow more than as it was this morning, but we still need to watch for areas of ice. anything that is still wet will be refrozing overnight. tomorrow more melting in store as those temperatures are into the low and mid 40s. then beenter into next week and we have a good shot at some snow showers almost every day next week and here's why the first storm system well off shore, but it is going to throw some snow in our direction, that will bring us our steadiest snow for monday.

pressure could form just to the south of us to bring more snow on tuesday. and then more snow showers as we work into wednesday. this isn't a long duration event of steady snowfall, but on again, off again snow showers that we're expecting, monday through thursday a possibility. a closer look at the monday timeline, start to see a rain-snow mix for the killed, but then turning to snow as we work in to the morning commute. then the snow shield spreads across from southeast to northwest as we work through the day on monday. and we could get some ocean effect enhancement from in, bringing heavier amounts of snow to the south shore, cape and islands. winter storm watch in effect for those areas. we could see win gusts up to 50 miles per hour, so it is a windy blustery day on monday, as well as watching out for the potential for coastal flooding. so how much snow do we see, well, here's my snow map at this point, one to three inches as you take it outside of

middleboro, three to six inches metro west through cape cod and the islands, and the higher amounts will be focused along the south shore i believe. definitely some colder temperatures in store for us as

(group chatter) dude, dude, dude. i think we're going to have to talk to each other or something. nooo. i don't like this elevator. (group surprised and laughter) how did that feel? was it fun being stuck? i do not like getting stuck! gets 84 miles on a charge. but the 2016 chevy volt gets an on a full charge and a full tank of gas. how's that for

>> history one way or another

that's something the bruins will throok avoid one year after mitsing the playoffs for the first time in eight years. teetering right now on the line in 2015 they are pretty much in that exact same spot for 2016. jack eichel making his second appearance at the garden with the sabres, four points, two goals, back in his debut on december 26. but it's the bruins striking first tonight. check out the puck movement. pasternak to krejci. tuukka rask spectacular between the pipes, 37 saves, probably wishing he could get this one back though. the back hand off the rebound, tied at one. in overtime, brad marchand, gets hooked and that means the hottest bruins gets the penalty shot, eight goals in his last eight games, he can walk it off

>> the penalty shot, he scores. >> hero for the b's, his 24th goal on the year is the game winner. bruins with a big two points on their home ice, 2-1 the final. countdown to kickoff for super bowl 50 is about 20 hours away. cam newton the star of today, the most dynamic play maker in football and the runaway winner of the league mvp. one final moment. brett favre the only first ballot hall of fame inductee in the class. coming up tomorrow on the super bowl sunday edition of sports extra, fred and mark will be in the house talking football and the weekend in san francisco for tom brady, that's tomorrow night at 11:25.
