art. captioning sponsored by cbs this is the "cbs evening news." >> good evening i'm jim axelrod and this is a western edition of the broadcast. 10 people were killed when a fedex tractor trailer hit the bus carrying some remarkable high school kids from newer los angeles who were on their way to see the campus at california state humboldt. the cash occurred 100 miles north of california. five student, three chaperones and the drivers of both vehicles were killed. we have more from teri okita. >> reporter: on this stretch of interstate 5, the only reminders of thursday's horrifying crash is a memorial for the 10 who died and investigators looking for clues. a big clue may have come from this couple, joey and bonnie

durand. >> i looked over and saw the fedex truck coming straight for me, and he was in flames already. >> reporter: that would indicate that the fedex truck was already in trouble before it crossinto oncoming traffic, clipping the dirands' rental car and crashing head on into the chartered school bus. >> it was so scary. we were wondering if anyone was going to gets out of there alive. >> reporter: melvin harris was on board the bus. >> when it hit, i couldn't really hear anything for a few seconds, and then i looked up and i saw i was bleeding. >> reporter: he was among the group of high school seniors on a college recruitment trip to humboldt state university. >> i broke the window and i was-- i couldn't think straight. >> reporter: seconds after some of the students escaped, the bus burst into flames. in several southern california communities, the shock is settling in for the five students who died, and their adult chaperones. among the victims-- michael myvett and his fiance mattison haywood. debra lloyd is myvett's grandmother. >> two angels to be with his

love. >> yes. >> and to be with his number one angel. >> reporter: among the five students killed, marisa serrato, whose identical twin, marisol was on another bus and uninjured. authorities towed what the mangled wreckage of the bus. >> our job is not just to determine the probable cause but to issue safety recommendations so these type of accidents are prevented in the future. >> reporter: the n.t.s.b. is looking into whether a fire suppression system, one recommended but never mandated, could have made a difference. but first, he says, they need to answer the most basic question-- why? human error is just one possible factor. the n.t.s.b. is also looking into mechanical failures, road conditions, and, jim, they say this could take weeks, if not months to pinpoint a cause. >> axelrod: teri okita with

this heartbreaking story. ter, thank you. cruise ships a continent apart are dealing with the same problem tonight. the norovirus has sickened hundreds of passengers on both coasts and for one of the ships it was the second straight outbreak. mark albert is with that ship in baltimore. >> it's really very hard. >> reporter: wijdan traish drove up from virginia to be on the next cruise out of the port of baltimore. instead, she's thinking of turning around with her grandson and going home. >> how can i go on a ship when there is contagious sick innocence there. >> i heard over 100 people got sick, and i don't want to get sick. >> reporter: instead of a phone call or e-mail ahead of time, traish says she was handed this all right when she and her grandson shareef arrived telling passengers their boarding would be delayed. >> they didn't say what kind of virus or sickness. >> reporter: their ship, "grandeur of the seas," arrived early saturday morning, after 107 passengers and crew got six during a week-long crew to the

bahamas. crews scrambled to clean the 900-foot-long ship bow to stern so it could depart again on the next cruise. returning passenger kim serio said she didn't eat for three days. >> oh, my god, we got so sick, i mean, asome virus i never had before. >> you could smell a reeking smell. >> reporter: it's the second straight saturday the ship has arrived home with more than 100 people sick. norovirus is also suspected of making 150 people ill on a princess cruise ship now docked in los angeles c.d.c. experts boarded both ships on saturday. in balt sisters, both longtime cruisers, were not scared off. >> the sooner we can get going, i'm ready for my vacation. >> reporter: so is wijdan traish, who decided to take her grandson on the cruise after all to avoid the disappointment. >> and he is so excited about that trip he couldn't even sleep well last night. >> reporter: royal caribbean gave passengers a $20 credit to

cover the cost of lunch while the ship was cleaned and promised to rebook at no charge those customers who no longer felt comfortable going aboard. mark albert, cbs news, baltimore. >> axelrod: ukraine's acting president called an emergency national security meeting today after armed pro-russian militants seized government buildings in several cities in eastern crook. katie stallard is in donetsk. katy, what are the militants demanding? >> reporter: they're demanding a referendum on federalization, which would effectively mean the creation of an independent state within the state of ukraine. some of them want to go further. they want to break away from ukraine altogether and join russia, and tonight in donetsk, the city where i am, they claim that the police are with them, that they are standing behind the protesters here, and similarly, a small town which came under attack by armed masked men in combat fatigues this morning, they say they are

holding two key buildings in that town, and with russian forces continuing to mass on the borders here, there are real fears this could be the next domino in this situation to. >> axelrod: so let me follow up on the fears this could be another crimea. how legitimate are those fears? >> reporter: well, the parallels are very striking. what you had there were armed masked mensing key strategic buildings. then a referendum, which became a question on joining the russian federation. and we know how that ended up. so there are real fears here that this could be another crimean scenario as the government in kiev are pushing it. they are conveeng a meeting of the national security council to try to deal with this, but the situation they are facing here in the east is very serious and very real, indeed. >> reporter: katie stallard reporting for us tonight from eastern ukraine. thank you. late today, the white house announced vice president joe biden will be traveling to kiev, the ukrainian capital, later this month in a show of support for the ukrainian government. severe weather in this country

is slamming the midwest tonight. powerful thunderstorms plowed through grand rapids, michigan, with winds approaching 85 miles per hour. the national weather system called it an extremely dangerous situation. heavy rain could cause flooding in the midwest tomorrow. the federal government is now stopped rounding up cablgths grazing on government land north of las vegas. cliveen bundy's family owes more than $1 million in grazing fees. the family scuffled with officers when they started to round up the cattle last week. armed protesters then showed up to support the bundies so the roundup is on hold for now. tuesday will mark one year since the boston marathon bombings. runners injured in the attacks, those who helped the injured, and law enforcement officers who chased down the bombers gathered undefor a huge group photo todao show their city is still boston strong. >> let's go, boston! >> axelrod: they came from all corners of the city, survivors, first responders, politicians, and well wishers.

they all gathered today on boston's boylston street as the anniversary approaches of the bombing that tore a hole through the city of boston and the nation as well. they gathered to show their strength. >> ready, folks? >> reporter: the "sports illustrated" cover shoot was held at the marathon finish line where hundreds had gathered last april 15 to cheer on the runners. it was just before 3:00 p.m. when two explosions seconds apart killed three people and injured 264 others. 35-year-old mark was one of those rooting on the runners at the finishthe finish roofer fro, massachusetts, lost a leg in the t. thst survivor to leave the hospital, he was at today's photo shoot. >> you know, it means a lot for all the people supporting us, you know, and it's a good day. >> reporter: carlos arredondo was also there today, the man in cowboy hat. he was giving out flags at the finish line last year in honor

of war veterans when the bombs detonated, arredondo, who lost a son in the iraq war, rushed to help a man lying on the sidewalk missing his legs. new cameras installed this week will monitor each stage of the race. security is, obviously, the top concern in boston for both runners anrunners and spectator. the race will be run a week from monday, but today, they came out to get their picture taken and let everyone know that boston strong is more than just a slogan. >> really, it shows you how strong we are as a city and how much we're actually feeding off of the survivors. ( cheers ) >> axelrod: a million people, twice the usual number, are expected to gather along the route this year to cheer the runners on. up next, the latest on protecting yourself from bleerk an internet security threat when the cbs evening news continues.

>> axelrod: reports about the so-called bly bug have rattled many intirnltd use. it's the name of a flaw in a security system that could put credit card numbers and pass words at risk. >> reporter: any web site with this little pad lock uses a security program called open ssl. it protects two-third of the internet. this week, researchers realize it's been vulnerable to hackers for close to two years because of a hole in the software. when you log on to one of those web sites, your computer communicates with the site's server on a secure, encrypted line. it's like a pulse constantly identifying your identity. what bly does is allow a hacker to break in and hunt around for your information, like user names and pass word. a server can't tell the

difference between you and the hacker so the hacker gets anything you have written on that web site and disappears without a trace. >> they're basically looking over your shoulder and witnessing all the information you're giving. >> reporter: alyssa bereznak is a columnist for "yahoo! tech." how do you fix it if it affects two-third of all web sites. >> users need to replace their password because during this two-year span they could have been eaves dropped on or an attacker could have seen their log-in information because the software was vulnerable to attacks. >> reporter: it's not clear how much information, if any, has been compromised, but major web sites like instagram, facebook, and google say they detected the flaw and have now fixed it. what was stolen is unknown. >> that's the scary thing about this is how much we don't be, and there's no way of being able to track this because it existed for two years heartbleed could be one of the biggest holes in the internet's history because every user was vulnerable and no

one even knew it existed. vinita nair, cbs news, new york. >> axelrod: some questions as we look ahead to tax day. who cheat and why? o'donnell

>> >> axelrod: just in case you've lost complete track of the calendar, we have a reminder-- tuesday is the deadline to file your income tax returns. the i.r.s. estimates $270 billion in revenue will be lost due to unreported income, this despite polls showing 90% of americans think cheating on taxes is wrong. our business analyst jill schlesinger joins us. the numbers don't seem to square. who is cheating? >> according to the i.r.s. it is the small business owners who are under-reporting their income by 43%, a big number. now, i don't want to suggest small business owners are bad guys and gals. it's just that they have an opportunity to report. remember, most of us are w2 employees. our companies are reporting what

we make to the i.r.s. we don't have a chance at doing it. but even in these small areas, tbhoaks have baby sitters or nannies, 90% of them are cheating on their taxes, just suggesting that perhaps we're not quite as against cheating as we say we are. >> axelrod: it seems to be a 87 opportunity. the i.r.s. also talks about something called the chump factor in explaining cheating. what is that? >> reporter: the i.r.s. found in a survey 73% of americans think that other wealthier americans are using tax loopholes that they don't get. so imagine if you think someone else is getting something, you tonight want to feel like a tax chump. you want to feel like you are exploiting the code to the best of your ability. of course, that can lead you to do some really dump things. when i was a financial planner for 14 years what, tended to happen is people would cheat on dumb, little things with such a big risk of an audit looming ahead of them, it seems crazy. >> axelrod: let me ask you about this other story going

around-- is the i.r.s. actually going after the adult children of dead people because the i.r.s. thinks those dead people owe backtaxes? >> reporter: well, there is some confusion. it is an i.r.s. social security problem but, yes, what seems to be happening is the government is saying if your parents got paid too much money-- maybe it was a tax refund, maybe too much in social security-- they can come back and take a portion of your tax refund to make up for your parents' generation. this is crazy-making, and is sort of impossible to fight it. only 10% of the folks trying to get that money released back to them are successful. they often have to hire eye lawyer to do it. so i think this is why senators barbara mikulski and barbara boxer are looking into it and saying this doesn't sound right. >> axelrod: and some legal challenges already under way. we'll see how those turn out. jill schlesinger, thank you. >> thank you. >> axelrod: it's one thing to get touched by an ankle but touched by a fan seemed to upset

an outfielder. curtis granderson caught a ball and was tapped on the back by a fan. he thought it crossed the line. they exchanged words and the fan was eject from the stadium. just ahead, take a look at this $120 million home and that is a mark-down. clb

>> prince william and kate, the duchess of cambridge, and baby prince george continued their royal tour. nearly 10,000 people greeted the couple. they laid flowers at a war memorial and the duchess of cambridge visited a children's hospice. when it comes to location, location, location, there's no more valuable location than greenwich, connecticut-- or at least that's the location of what's believed to be the most expensive private home ever sold in the united states. the 13,000 square foot mansion

sits on 50 acres of waterfront property and comes with a pool, tennis court, and two islands. this all went for $120 million, which may actually be a bit of a bargain because that is $70 million below asking. an extremely rare easter egg, and now pretty good nest egg, goes on display in london on monday. it's a golden fab jay easter egg worth about $33 million. a midwest scrap metal dealer bought it at a flea market for $14,000. he planned to sell it for scrap before founding out it was a lost piece of historic art. and it was a beautiful day for a parade in washington, d.c., which is exactly what they had planned there. the national cherry blossom festival parade, after a brutal winter, it is especially nice to see the blossoms in full bloom. and our own norah o'donnell was one of the parade's cohosts. coming up, the height of

artistry deep beneath new york city.

>> axelrod: weclose tonight with a story about sightseeing in new york city. it turns out it doesn't always involve looking up. as jill wagner shows us, in at least one case, it's all about looking down. >> reporter: one of the great architectural treasures of new york city is underneath this plaza. the old city hall subway station, shuttered for 70 years and left to collect dust in the dark, even with its majestic arches and shand leers that rival any cathedral. >> when it opened it was called the mona lisa of subway stations. >> reporter: it was one of many structures built by the guastavino family, now being celebrated in a wonderous exhibit at the museum of the city of new york "palaces for the people." john ochsendorf is a professor at the massachusetts institute of technology and curator of the exhibit. he's dazzled by the marriage of

beaut and function in guastavino's work. >> this particular staircase goes up for about 10 stories. this is absolutely awe-inspiring as a work of technol but also as a work of art. you know, i'm an engineer, but i struggle to explain how this stands up. >> reporter: the guastavinos were spanish immigrants who brought centuries-old mediterranean techniques to the united states in the late 1800s. they used the technique called thin-tile vaulting to create a signature and patented style. it was inexpensive, light weight, and strong. >> the mortar would set enough to hold the weight of a single tile. >> reporter: in all, their domes, arches, and vaulted ceilings grace more than 250 buildings in the new york city, like the ellis island registry room, and theica he'deral of st. john the divine in harlem. >> if anyone finds a guastavino billion i do not know about, i

will buy you lunch. >> john ochsendorf has been on a safenger hunt for these sites for years, and today the realization of a lifelong dream-- >> i have a dream some day it could be reopened either as a station or a museum. >> reporter: he traveled by train for a private tour of this underground treasure, hidden for decades in the heart of new york city. jill wagner, cbs news, new york. >> axelrod: gorgeous. and that's the cbs evening news for tonight. later on cbs, two editions of "48 hours." for now, i'm jim axelrod in new york. for all of us here at cbs news, thanks for joining us and good night. captioning sponsored by cbs captioned by media access group at wgbh access.wgbh.org cc california. the evasive
