12-year-old joi coleman was there with her. >> when she asked, help me, i couldn't help her because i knew i was going to be shot, too, because he didn't stop shooting. couldn't. >> reporter: roughly four hours after this first shooting, investigators say dalton killed 53-year-old richard smith and his 17-year-old son tyler, a high school senior, who were looking at cars at a kalamazoo dealership eight miles away. fired. >> reporter: less than 20 minutes later, authorities say dalton showed up at a cracker barrel restaurant and shot five more people in the parking lot. four women died, 60-year-old mary jo nye, a retired high school teacher, and her sister-in-law, 62-year-old mary lou nye nigh, a retired mother of two. 68-year-old barbara hawthorne, who retired from the kellogg's food company after 22 years, and 74-year-old dorothy brown, who was retired and helped seniors

matt mellen was one of the least passengers dalton picked up that night before his arrest. >> we were driving through median, driving through the lawn, speeding along, an then finally once he came to a stop, i jumped out of the car and ran away. >> reporter: uber confirms to cbs news that some passengers called the company on saturday night complaining about dalton's erratic behavior. james block is dalton's neighbor and friend of 17 years. >> the guy, friendly, family man. he loved his kids. >> reporter: well, that friend was also surprised to hear that police found a large group of weapons at dalton's home and an tonight. the prosecutor tells us a 14-year-old girl who was shot and is in critical condition in the hospital tonight was originally declared dead. she was on life support awaiting organ donation when suddenly, scott, she squeezed her mother's hand. >> pelley: anna werner with the story for us tonight in kalamazoo.

to presidential politics now. republican donald trump fresh off a victory in south carolina on saturday has a big lead heading into tomorrow's caucuses in nevada. rival ted cruz had to put ort a fire today after a top aide violated the commandment against bearing false witness. here's dean reynolds. >> reporter: after weeks of accusations that hs running a deceitful campaign, the texas senator fired the man in charge of his communications and messaging. >> i have made clear in this campaign that we will conduct this campaign with the very highest standards of integrity. that has been how we've conducted it from day one. >> reporter: rick tyler's departure was triggered by a video of marco rubio walking by a cruz campaign worker reading the bible. but tyler posted an article on social media that said rubio

answers in it," which the rubio took as a dig at the senator's religion. an apology followed. cruz dismissed tyler anyway and called out their rivals. >> if other candidates choose to go into the gutter, we will not do the same. >> reporter: the republican field has narrowed and the stakes have risen. the bitterness among the three leading campaigns has deepened. rubio new york a bid to consolidate mainstream republican support, called the cruz campaign absolutely deceptive and a super pac supporting the senator lumped cruz together with trump and found both unacceptable. >> trump: erratic, unreliable. cruz: calculated, underhanded. >> reporter: trump drained all of his fire on cruz, unleashing a storm that called the texas senator "the biggest liar in politics" who should be disqualified as the winner of the iowa caucuses. but late today the cruz campaign released a defiant memo that shed some light on the campaign's thinking going forward.

marco rubio cannot defeat donald trump, that rubio has yet to win any state anywhere and that ted cruz has more money in the bank, scott, to continue to fight. >> pelley: dean reynolds covering the campaign in las vegas. dean, thanks very much. polling shows that hillary clinton is leading bernie sanders nearly two to one in next saturday's primary in south carolina. she won nevada over the weekend by five points, bug her back on track after her drubbing in new hampshire. here's nancy cordes. >> reporter: yes, that is former president clinton bouncing for joy with campaign staffers in nevada. after his wife stormed the vegas strip for two days and then won the state's most populace county by ten points. do you think secretary clinton just outhustled you a little bit at the end? >> no, i don't, as a matter of fact. look, i'm very proud of what we

is a blow for sanders, who is tied with clinton in the tell gatson count until you factor in superdelegates, top party officials who are tree to back either candidate. that gap will grow if clinton prevails, as expected new york south carolina. in texas this weekend, she accused sanders of misleading voters about his plans. >> i don't think it's right to look a person in the eye who is hurting and needs help and tell them that if they vote for you, you will get $5,000 in health care but only have to pay $500 for it. >> reporter: sanders stands by his math. >> that's not misleading. those are the facts. >> reporter: as you know, some liberal economists... >> check out who these liberal economists are and you'll find out who funded them. >> >> reporter: the economist argue that his "extreme" claims about the benefit of his proposals could undermine the

none of them are paid by the clinton campaign, though a couple did work for former president bill clinton. they say many economists share their concerns but sanders told us they didn't take the time to crunch the numbers themselves and that plenty of experts side with him, scott. >> pelley: nancy cordes, thanks. well, curving the delegate numbers for us is john dickerson, our cbs news political director and anchor of "face the nation." john, huge primary nights coming on march 1st and march 15th. can anyone catch trump? >>. >> reporter: well, marco rubio's strategy is he's trying the claim he's the one mainstream alternative to donald trump, but he still hasn't won a contest and his best shot for a decisive win may in the happen until march 15th when the more moderate electorate in ohio and florida vote. before that rubio has to beat back a challenge from john kasich for the mainstream title, and do well enough to survive on super tuesday, march 1st, when

have electorates that favor donald trump and ted cruz. >> pelley: trump might have a lot of mow -- momentum coming off of march 1st then? >> reporter: that's right. ted cruz hopes all his chips are riding on march 1st, as well, super tuesday. that's when his home state of texas votes, as well as other states like alabama, arkansas, oklahoma and tennessee, which have a large share of strong conserves and evenge cal voters, groups he does well with. but that strategy took a blow saturday in south carolina because it has an electorate with that same make-up and where cruz went head to head with donald trump and he still lost by 11 points. >> pelley: john dickerson, anchor of "face the nation," john, thank you for the insight. today the u.s. and russia agreed to a partial ceasefire in syria to start on saturday, but it won't stop the fighting. two important forces, isis and the al qaeda affiliate called al-nusra were not included in the agreement because they're terrorist groups, and about

isis. yesterday isis claimed responsibility for bombs that killed at least 100 in suburban damascus, and our elizabeth palmer is there. >> reporter: all day the men of sayeeda zainab carried blast victims to their graves. on the faces of the women, shock and grief. these friends are mourning 22 -year-old. "our hearts are broken," they say. "what did she do to deserve to die?" but there was anger and frustration, too. at the bombsite, local residents had pitched in to clean up and make the street safe again, but furious that isis had managed to smuggle three bombs into their tightly knit community. i'm standing just a couple yards from where the biggest bomb went off. it was a car bomb about 4:00 p.m. just as the kids were

the bulk of the damage is epic. the fronts of the buildings have been blown clear off. everybody that lives inside and the merchants who ran the shops on the ground floor, they're all dead. this video shows the frantic moments right after one of the explosions. survivors rushing to help the wounded. you might think people who have witnessed such carnage and who today are burying more than 100 family members and friends would welcome a pause in the violence. not so. are you optimistic that there will be some kind of truce? "no way," abu mahran tells me. and everyone in the crowd agrees. "we don't want a ceasefire until all the terrorists are out of our country." it's not a good sign for this proposed truce when even the citizens are not on side. and the people we spoke to today, scott, are very sceptical

they say in a war this complex and savage, there's just no way to coordinate all the factions laying down their arms. >> pelley: liz palmer with a rare report from inside syria. lids, thank you. well, today the u.s. supreme court met for the first time in 30 years without justice antonin scalia. his empty seat today was a reminder of the political battle over how to fill it. and here's our chief legal correspondent, jan crawford. >> reporter: justice scalia's seat on the bench now is draped with a black cloth as the justices return to work the first time any of the eight have served on the court without the larger-than-life scalia. chief justice john roberts started the morning session with a tribute. "we remember his incisive intellect, his agile wit and his captivating prose, but we cannot forget his irrepressible spirit. the 79-year-old scalia was laid to rest on saturday after a

paul, a catholic priest. now the fight over his successor begins in earnest. the president is reviewing files of possible nominees while republican leaders are vowing to block anyone the president sends up. democrats accuse republicans of being obstructionist, but when democrats controlled the senate and republican george h.w. bush was in the white house, then-judiciary committee chairman joe biden proposed the same thing republicans are doing now. >> once the political season is under way, and it is, action on a supreme court nomination must be put off until after the election campaign is over. >> reporter: current judiciary committee chairman chuck grassley, a republican, immediately agreed. >> in his heart of hearts, he understands why this senate must do what he said it must do in 1992. >> reporter: now in the past it's taken about a month for a nomination, but the president is likely the move more quickly than that.

court for us tonight. jan, thank you. fares as low as $1 have drawn mega-bus. well, yesterday one of its buses burned outside chicago. this has happened before, and we asked don dahler to take a look. >> reporter: sunday's mega-bus fire began with a blown tire. flames engulfed the bus. >> it was very horrifying. highway. it was official. >> reporter: this wasn't the new jersey-based company's first brush with tire-related disasters. in 2012, a 25-year-old graduate student in illinois was killed in this crash, allegedly caused by a blown tire. 47 passengers were hospitalized. there have been at least five other incidents involving blown tires on mega-buss, including this one in 2014 that caused the bus to slam enter a guardrail on i-95. at least one law enforcement has been filed claiming there is a problem with the buses carrying too much weight.

center for auto safety. how does weight affect tires and tire safety? >> if a bus is overweight, in the worst-case scenario, the tires can rub against the wheelwell, which generates friction, heat and ultimately a fire. >> reporter: in the last 24 months, safety inspectors found 29 maintenance violations considered an imminent hazard to mega-bus drivers or passengers. mega-bus says it carries ten million people a year in its fleet of 275 buses. and they released a statement saying, "safety continues to be our top priority and megab us.com is fully cooperating with authorities. the federal agency that oversees travel issued an advisory about overloaded buses in 2012, but ditlow says that's not enough. >> some of these buss have been in heavy traffic. if it couldn't pull off to the side of the road, there might have been a catastrophic fire before the peopleould get out

>> reporter: ditlow says the buses are weighed to make sure they comply with safety limit, but that happens before they're loaded with passengers and baggage. >> pelley: don dahler, thank you very much. breast cancer rates remain the same, so why is there a big increase in vasectomies. and a centenarian dances with joy after achihi

jon, what's going on? >> reporter: scott, cancer doctors have noticed this trend. the jump in the overall mastectomy rate is fueled by several things, including greater awareness generated by celebritiesike angelina jolie and rita wilson, who have gone public with their decision to have preventive mastectomy. also breast reconstructive surgery has gotten a lot better and the cosmetic result is usually excellent. in addition, we now emphasize genetic risk and family history, and with that information, many women just want to lower their risk as much as possible, and finally, many women want to be done with all the screening, which carries the risk of false positives, unnecessary biopsies and a lot of worry. scott, this is all part of what we're seeing more and more of these day, which is specialized and personalized medicine, which is giving women more choices in their own treatment decisions. >> pelley: dr. jon lapook. jon,ings that very -- thanks
