>> and i'm jim vance. those arrests stem from that disturbance after a maryland basketball game a couple months ago. and it comes after intense analysis of pictures from dozens of securities cameras. jackie benson is on the campus now with more on this. jackie? >> reporter: jim, six more university of maryland students are now facing charges, months after the event occurred. university of maryland students described it as the rowdy celebration of a basketball victory. police called it a riot. some students have claimed they were beaten without prove sahratian by prince george's county police. but with graduation just one week away, university of maryland police announced six new arrests following their own investigation into what happened the night of march 4th. the students and the charges, 22-year-old john felmer, trespassing, destruction of property, riot. 22-year-old joseph michael mcellan, trespassing, riot. 19-year-old john michael winters, destruction of property. 20-year-old joseph margeaux, destruction of property. 20-year-old omar ali, destruction of property. and 19-year-old alex mccain phoenix, malicious burning, trespassing, riot. investigators spent months combing through images from dozens of security cameras. some students accused university police of being overzealous in their investigation. >> it's showing how the culture right now is so anti-police and nobody knows who to trust anymore, what to trust. there is a lot of people who, you know, are -- since the arrest, oh, the cops must have done something to force them into, you know, into confession of some kind. >> some people are definitely concerned about it. but i think it sort of died down a little bit. >> reporter: university of maryland police spokesman suspends the investigators, if convicted, the students face a possibility of fines, jail time, and expulsion. jim, back to you. >> jackie benson, thank you. ambulances were called to west springfield high school in west fairfax county after three students got sick in school. in an em to parents, the principal says the kids algdzly smoked something before school that made them ill. a fourth student who was with them was taken to the hospital as a precaution. neither school officials nor the police oifd the substance that was smoked. the students are all expected to be okay. but they could probably face punishment. the fbi raided several houses in the northeast today as it followed the money trail from a failed attempt to bomb times square. three people were taken into custody, two of the suspects were arrested in the boston area, the third was arrested in maine. all of them were arrested on immigration violations and not criminal charges. federal authorities think the men provided funds to faisal shahzad, the pakistani born u.s. citizen accused of leaving a vehicle full of explosives in times square two weeks ago. >> one of the things that they did is to provide him with funds. and so we're trying to trace back to see exactly what was the nature of the transactions, what the purpose of the sharing of debt of those moneys. >> faisal shahzad told authorities he got money for the plot through a system and an informal currency exchange system used among muslim immigrants. it's possible they had no knowledge of shahzad's plan. president obama visited times square this evening to personally thank the officers who have responded to the bomb scare. at a command center, the president praised the new york police department's coordination with state and federal law enforcement on counter-terrorism efforts. stop a massive oil leak involves a pipe only half a foot in width. tonight crews are trying to thread that pipe in a larger tube that's leaking on the ocean floor. once attached, it is supposed to suck the oil to a tanker at the surface. bp, british petroleum, that is, says if thissen does the work they'll try to use a small containment box. meantime, the owner of the oil trig, transocean, asked a federal court today to limit its liability to $27 million. one of the major draws for people living in montgomery county is the park system there. there are thousands of acres of parks. but if some proposed budget cuts go through, the policing of all that land will fall on the shoulders of a few dozen officers. darcy spencer has our report. >> reporter: 18 of the 88 officers in the maryland national capital park police force could lose their jobs because of a budget short fall. >> you know, the parks will not be safe. again, like i'm saying, you're taking 20% of the workforce and firing them. >> reporter: the police union says the proposed reduction in force the risk cuts that will take us back to september if they recruit. it's one proposal to deal with the county's billion dollar deficit. >> these are real people, real families, real homes, real mortgages. >> they're fighting a battle for the future of park police on two fronts. the first, the risk. second, fighting the county executive's recommend togs eliminate the department and mercy officers into the county police department. >> sometimes call for tough measures. however, by eliminating the park police, you're creating a safety iss issue. >> reporter: a decrease in police president koens mean an increase in crime and that includes gang activity. a spokesman for county executive says that public safety were to be jeopardize, the county would not consider merging the departments. but supporters of the plan say there are some duplications including dispatch and that a merge makes sense in tight budget times. >> is there a better way to take that specialty that our park police have in patrolling our parks and make that more decentralized and part of montgomery county police? by so doing, can we achieve efficiency and savings? >> park users were against cutting officers and merging the forces. >> i think it's the worst thing they could do, especially in where it's become so popular in merging the departments. >> reporter: darcy spencer, news 4. still ahead on news 4 at 11:00, holland mourns to kill those killed in a plane crash. a lawsuit calls into question the legitimacy of online reviews and whether they're manipulated. liz crenshaw has that report. a college graduation speech ends with a unique marriage proposal. plenty warm tomorrow and still a risk of

arrived at the hospital in tripoli today. he greeted them with a smile. 24 hours after a terrible crash in maryland, police are looking at alcohol and excessive speed as potential factors. 2-year-old camaro brown of landover, maryland sh was killed in that wreck. police say she was thrown from the car that was driven by her mother after that car veered off bright seat road near fedex field and then hit a tree. the impact split the car into pieces and indecreed blit girl's mother escaped with only minor injuries. one of the biggest fare hikes in metro history is coming. the trans it system is still working out the details. people who take metro rail could see fares rise nearly $1 a ride depending on the time of day and the distance traveled. bus riders pay an extra quarter per trip as fare goes from $1.25 to $1.50. the fare increases would take effect in july which is the start of metro's new fiscal year. the agency has to close a nearly $200 million budget deficit. coming up tonight, the legitimacy of online reviews. i'm liz crenshaw. a closer look at online reviews. who's behind them and can you trust what you read? my story is coming up. veronica will show whus storms could develop tomorrow. and the washington humane tow site gave a cat the gift of visi we could all use a recommendation on where to eat or where to find the best deal. bhaut about the advice of a complete stranger? millions of americans rely on online reviews. but how trustworthy are they? liz crenshaw is here with more. hi, liz. a lot of people wondered about this. >> we all do. we all turn to the internet for a wealth of information including shopping advice. but a recent lawsuit filed against the popular website yelp has some consumers and business owners second guessing the legitimacy of some of those reviews. >> i wrote the review. i posted it. but when i went back on to yelp to see if it was published by the site, it wasn't there. >> reporter: debbie has been going to xyz salon since it opened ten years ago. she posted a review on yelp, a social networking review site after noticing a negative review posted that was dated a few years ago. she says there were no recent reviews posted, not even her own. >> which i thought was odd. i thought i never posted a review, maybe i did something wrong. i tried it again. posted my review. i looked on yelp and once again, no review. >> reporter: she told the salon's owner and part time stylist for nbc about yelp's site and negative review that stands. >> did you ever contact them and say what happened? >> several times. they say they have a filter in place. if they believe i paid for a good review, they would back off again. i said so you believe that everybody that's ever said anything nice about me for four years i paid them? you know? that doesn't make sense. >> reporter: several business owners are accusing yelp of manipulating the site's content. 11 businesses are part of a class action lawsuit against yelp including this d.c. restaurant. the lawsuit alleges yelp sells advertising to business owners in exchange provides favors such as removing or relocating negative reviews. creating and posting positive reviews and insuring negative reviews will not appear in google or other search engine results. this woman, a facial spa owner in california, says yelp sales people called her repeatedly and asked her to buy advertising in exchange for more exposure and better "control of her reviews." what does that mean? >> this is probably that you can remove the negative reviews and, you know, carry on with your good reviews. that was very fishy answer. >> reporter: yelp tells us the lawsuit claims lack merit and fight the suit vigorously. it does not remove or move reviews in exchange for advertising or response yourship. it does use a filter system to fight shilz and malicious content and treats advertisers and nonadvertisers equally. allegations against yelp bring up a valid question, can you trust online reviews and the opinions of complete strangers regardless of what site you use? >> everyone in the online space is a researcher and not just a reader. and so you have to always be a qualified reader. you have to gauge credibility. >> reporter: yelp reports more than 30 million monthly visitors. in a study done by opinion research corporation, 84% of americans say online reviews influence their purchasing behavior. how do you feel about online reviews in general? >> i think that's fair enough if you're allowing everything out there. >> reporter: now yelp says it recently made changes to its website. it now allows business owners and customers to read the filtered reviews. so admitting that there are filters and also remembering that we have to be thoughtful when we read these things from people we don't know. >> how long will people keep using them? >> it's extremely popular. people say they actually read the stuff out there. >> but if we can't trust them, how long will that continue? >> another question asked. i have never read one of those things in my life. i couldn't care what somebody else says. >> because you only care about -- >> yeah, i trust you. >> all right. >> thanks, liz. >> you're welcome. >> things are going to get a little crazy tomorrow afteren into and early evening. >> crazier? >> crazy with thunderstorms. we had one batch that came through yesterday. didn't have the warnings out for the area. but tomorrow could be a different story for us between 4:00 and 8:00. so let's take a look outside now. i guess this is the lonely guitar player, right? for your weather enjoyment. the high temperature today only 63 degrees. and tomorrow we're talking about temperatures off to the races. the mercury is going to rise. it was on the 1st that we got up to 88 degrees. tomorrow, i think we'll hit 87. maybe 88 for the year. april 6th and 7th whether we got up to 90. those back to back 90-degree days. 61 degrees is the temperature right now. the dew point is at 52 degrees. we have a wind right now that's out of the south and southeast. generally through the area. not a huge range at all or spread in temperatures anywhere from the east and now 59. mart inzburg, 57. winchester, 57. high pressure off the coast. now we have a south easterly wind. this is the warm front that's going to move through and really warm things up in a hurry. we'll start out at 60. by 9:00, we'll hit 70. by 80 degrees by noon time tomorrow. and with enough breaks in the cloud cover, we'll be looking at storms across the area. storms in western new york right down through missouri where there's been some heavy rain today. heavy rain in michigan. primarily the reports on storm damage, wind damage throughout kentucky and wind damage around missouri. that's what i think we could see here. our main threat of the storm system is tomorrow. high winds, possibly some hail. and some havy rain. brief heavy rain with that storm system coming through and frequent lightning. 70 right now in raleigh. 67 and close to 80. that warmth spreads over us quickly tomorrow. we'll get sunshine in here by about noon time tomorrow. and, again with, heating and the moisture and the powerful weather system coming in on us, storms by about 4:00 p.m. tomorrow. and some rough weather until 8:00 until that storm system crosses the area and makes its way on down to the south. once it does, that will be the setup for a pretty fantastic weekend coming our way. with maybe some sunshine and some breezy conditions for the weekend. this is the whole area here under a slight risk of severe thunderstorms for tomorrow. so, again, high winds, some possible hail. philadelphia all the way down to paducah, kentucky, nashville and certainly across our area. so tomorrow morning, patchy fog. dampness again. 59 to 63. south and a southwesterly wind that will be picking up throughout the day tomorrow, especially with any of those storms. some gusty storms for us. the high anywhere between 85 and 88 degrees. so isolated severe weather is on tap for your friday afternoon and early evening. a beautiful weekend. 76 on saturday with sunshine. 73 on sunday. breezy both days. rain returns by about late tomorrow -- late on monday evening and through tuesday. and, of course, you can always check your forecast by tuning into the weather channel. >> and did i hear you say before you were ready for the weekend? >> definitely ready for the weekend. >> all right. that's good. >> still ahead tonight, a student comes to the rescue of his spanish teacher when she starts to choke. and sports, the celtics and cavaliers, did you see it? can you believe it? the nats are out west tonight where the air is thin. >> air is thin, weather is chilly. it is 45 degrees and it is drizzly everywhere. really rainy night in denver. nats and rockies finally got going after a 45-minute rain delay. john landon on the bump after missing the last start. and the weather didn't phase the nats' opening day starter one bit. at least not yet. still going on. the nationals are in control. the nats fans out there in denver. and they had to like this. top of the first. ryan zimmerman with a big fly in the mile high. and this one is of the two-run variety. puts the nationals on top 2-0 early in the ball game. how about this? mike rizzo bramiving the elemen. a hoody and can you survive anything. first start, pretty solid. he goes four and two-thirds. didn't give up a run until the fifth. fifth inning, two on, two out. and zimmerman said get out. career home run number 99. this one a three-run shot. it gives the nationals a 6-0 lead. right now in the sixth, the nationals up 5-4. talking hoops now. this is a game that is shaking the nba. could make some serious plays. the cavaliers knocked out of the playoffs about it celtics. now the wait is on to see if lebron james will stay with his team or run to new york, chicago or miami. king james played more like a princess in game five. tonight, though, he almost had a quadruple double, 27 points, 19 rebounds, 10 assists, and nine turnovers. the last stat very ugly. we're going to get things started. here is king james. desperately needed a win. ray allen driving and dishing to tony allen. look out below! dunks over antoine jamieson. antoine, by the way, five points in the game. celtics up 51-49 at halftime. third quarter, celtics on the break. the pass broken up. lebron gets it. he is going the distance. the hoop and the harm for lebron james. fast forward to the fourth quarter. cavaliers down by four. trying to make it a ball game. lebron, off his foot. rondo picks it up. swoops up and in. rondo, another stiff contest for him, 21 points and 12 assists. later in the fourth, celtics run ago way with it. mo williams, loses the ball. tony allen gets it up to rondo. drops it off to kg. and the big ticket zundunks it home. wallace said here we go. there you can see kevin garnet. 94-85 is the final. so what exactly did garnett say to lebron? >> i just told him keep your head up, man. i've been there. and you have a very, very, very bright future. make decisions based on you and your family. best advice i can give him. >> you know, you saw that video at the very end. lebron stripped off the jersey before he got off the court. you have to wonder if it's the last time that he could be wearing that cleveland cavaliers jersey. we'll be talking about this for months. i don't think lebron knows what's going to happen. >> he has time. >> he has plenty of time. he's going fishing. >>
