was a long-time secret service supervisor because they had been interviewed by the agency when his security clearance was updated now and again. that's why news of this scandal comes as such a shock here. the secret service scandal involving agents partying with alleged prostitutes and a dispute over money at a hotel in colombia is hitting home. here in ashburn, virginia 48-year-old david chaney is not answering his door one day after he resigned under pressure as a secret service supervisor. he reportedly posted on his facebook page a picture of himself on duty behind then vice presidential candidate sarah palin with a comment "i was really checking her out" if you know what i mean. palin responded on tv saying, well, check this out, bodyguard. you're fired. neighbors along hay road in ashburn say this is not the david chaney they know. >> i'm surprised. i'm shocked.

he seemed like a very nice person, so seeing his name on that scandal surprised me a lot. >> i don't believe he is involved, but realistically i don't really have any proof or guidelines so whatever the governments decide will be based on what they judge him. >> reporter: television news crews have staked out the neighborhood waiting for any comment from david chaney or any development in the investigation. one house has a sign on the door that says, don't knock or ring the bell. we have no information. news crews that were staked out here all day told me that chaney asked the loudoun county sheriff's department to arrest anyone trespassing on his property. he obviously does not welcome this attention. reporting from ashburn, chris gordon, news 4. back to you. >> thank you. now our weekend weather. get ready for a tale of two different days this weekend. >> it's about to take a wild

turn. storm 4 meteorologist veronica johnson has your first forecast. veronica? >> this is going to be pretty crazy. this is something i haven't seen in a while over our weekend where you've got split personalities and big changes taking place during the weekend. out there right now, it's nice and quiet. and it doesn't look like anything is going to be happening. right? but it is. as far as the pollen goes, that's been creeping up. we've had two dry days. it's at 134 grains per cubic meter. yes it's still tree pollen but is at least on the decline. grass pollen coming along now. it's low today but we'll see it climb especially through the month of may. the storms that we're talking about for the weekend, we have one area of low pressure just west of detroit, another one north and east of dallas, texas. those are big ls on the map that will be affecting our weather this weekend. we're in the 70s now. it's again delightful out there. no problems whatsoever but we've got storms to talk about. the possibility of severe storms with hail, high winds, and we've

got winter to talk about, too, believe it or not, coming up for the weekend. i know. really crazy. so we'll talk temperatures so that you can plan accordingly. if there is going to be any dry hours where you can get anything squeezed in this weekend. >> thanks, veronica. a prince george's county volunteer firefighter made a big milestone today in recovering from serious burns he got battling a house fire. kevin o'toole was discharged from the burn unit at med star washington hospital center this afternoon. on february 24th he was burned over half of his body while fighting a fire in riverdale, maryland. as he left the hospital today, the 21-year-old was greeted by family and fellow firefighters. he described what this day means to him after undergoing so many painful treatments. >> i'm feeling pretty good. it's a great accomplishment from being so badly injured to walking out of here in two months. it's a great privilege to walk out and see everybody. every day is a good day from now on. >> after leaving the hospital o'toole boarded his fire truck and headed back to visit his

fire station. his next step in recovery is physical therapy. he'll be getting treatment in his parents' hometown of beth page, new york. three judges will decide whether to reduce the sentence of a rockville man who was the driver in a deadly crash back in may in olney. kevin coffey pleaded guilty to drunk driving and was sentenced to 20 years behind bars. news 4's richard jordan is live at the montgomery county courthouse in rockville with the story. >> reporter: jim, that three-judge panel is now considering their options whether or not they would like to change the sentence that was handed down earlier this year for 21-year-old kevin coffey. he was just 20 years old at the time back in may when he was drinking and driving. he had four friends in his car. he crashed. three of those passengers were killed. the friends and family of those victims were here in court today. many of them were wearing bright yellow t-shirts that say, think before you drink and drive. now, coffey did have a moment to speak before the court. he showed some remorse.

he says he asked himself often why he was saved and why his friends were killed. his mother and sister also spoke. they say they feel that this 20-year sentence is nothing more than revenge and the judge who imposed the sentence acted hastily mostly because of the ainge inner the community. on the other side you had the parents of these three young victims. they all said that they feel the sentence is appropriate. in fact the father of one of the boys killed, the father of spencer dat, said he would be okay if these three judges decided to increase the sentence. that is an option the judges could consider. but right now they are behind closed doors discussing this. the arguments are over so simply now just waiting for these judges to come back and of course no one wants to know more what's going to happen, what their decision will be as much as coffey, his family, and then the family of these three victims. so we'll be watching it. if there is a development today, i'm not sure if a decision will come down today but if there is one we'll keep you posted on

mother was too ill to dictate that will. in the youtube video peebles says he will hold services this weekend for his supporters. >> it hurts my spirit to know that this building that has been opened to the community for the last 15 years is locked down. it does hurt a little bit that there is police presence and those that are prohibiting people from entering into the house of worship. guess what? the house of worship is wherever you are. >> services will be held this sunday at 10:00 a.m. at the metro points hotel on annapolis road in new carrollton. today the public got the first chance to see the space shuttle discovery at its new home. it was an overwhelming response at the smithsonian in chantilly, virginia. our photo journalist chester panzer captured the sights and sounds on opening day. >> the stick and the throttle. when we're flying up in space

>> it's amazing to see something from space. >> you see it on tv but when you get a chance to get up close to it and see an actual spacecraft that's been shot up into space and comes back down again you're actually right up close and you can almost touch it. >> the museum curators say they don't plan to clean up discovery and want it to look as much like a working shuttle as possible. you can see the shuttle during museum hours from 10:00 a.m. to 5:30 in the evening. yeah, it earned all those dings and wrinkles. >> it did. >> i want to go. >> amazing to see -- we all want to go inside. >> yeah. >> we're not invited yet. maybe. >> just the three of us. we'll be the first. >> a good time to step in. >> could be a good weekend to step inside a museum. huh? >> yeah. you have to get there but it is going to be -- we have a big storm, two storms, big rains for the weekend and big changes that are going to be taking place. a lot going on through the

pretty much all over the weekend. let's head over to the weather wall and i'll tell you all about it. it's really going to be two seasons for the weekend. we've got summer and we've got winter, truly, because it is going to feel a lot like february, early march, second half of the weekend. we get the upper 70s to around 80 degrees. first part of the weekend. and with that we'll get a pretty powerful system so some thunderstorms that could be producing with the colder air coming in. a little bit of small hail around the area and some strong winds. the wind out there now southwest at 12 miles per hour. 70 for your temperature. beautiful sky there. only a few high clouds. and some of the temperatures to our west, fairfax, virginia at 66. good afternoon. a stack of 74s college park and silver spring, maryland and 71 degrees currently folks down south, i-95 in fredericksburg, virginia. so a nice evening. 5:00 and 7:00 we drop to 69. then 67 to 64 degrees. you know what, folks? that is comfortable. it is going to be a very nice evening. even the start to the day

tomorrow is going to be not too cool at all. this, though, isn't cool. the big storms gathering down south. look at arkansas, west of memphis, tennessee and around houston. they're getting hammered, a couple severe thunderstorm warnings there. the front all the way up to the north in indiana just east of chicago, illinois right now. so one long front and a couple low pressure systems. the first low is with this cold front so for early tomorrow morning there is 10:00 a.m. we're cloudy. might be a few light showers around the area but the best bet of rain is afternoon time. you want to get anything in, do it before noon tomorrow. afterward, it's more showers that'll fill in and some thunderstorms, too. stormy again, could have high winds, lightning, brief, heavy rain. and then you've got the low pressure moving up the coast for sunday. you can see where most of the heavy rain is. it's going to be east of our area but i'm thinking, you know what? it depends on the exact track of the storm and the intensity by the time it gets close to us. so there could be a lot of rain,

a lot more coming in east of i-95. inch totals by the time we get to sunday morning at least close to that d.c. down to the south and then watch this thing wrapping up as the low moves up the coast. this is sunday, 3:00 p.m. still wet across the area. and there we are for monday, too, where enough cold air could move in to produce a little bit of snow out west. i said it. snow. light snow afrin a few flakes. your evening again gorgeous. 59 to 64 degrees. this is the evening when you really want to get out and make the most of your weekend. i'm going to just include it in the weekend. we're 54 to 60 to start your day. 74 to 79. so that's short sleeves and short pants type weather. then almost like winter type conditions for sunday. it is going to be breezy to windy. 55 the high with wet weather around. you know what? you have to go with a coat. >> all right. thanks. still ahead on news 4 at 5:00 police are desperate to find a witness who is key to

years for the terps and quarterback c.j. brown. you will know them both well by season's end, win or lose. >> come on. come on. >> reporter: after weeks of beating each other up, tomorrow's spring game will be the last chance before fall to put on the pads and let out a little aggression. with two new coordinators in the mix it's also a good time to earn a starting job. you might be surprised to know it's not perfection that coaches are after but a little consistency would be nice. >> offensively i'd like to see us get off to a little bit quicker start and i'd like to see the consistency, you know, throughout. that's the one thing we really haven't seen in the scrimmage. >> don't let it come down. >> i think the skill set is there. you know, with c.j., he's shown the leadership. he has the arm talent you want in the position. he can make plays with his feet. we have to get him to consistently do the things mechanically to ensure he is throwing the ball and getting us

in the right plays. >> the biggest thing was just getting consistent. taking a year off with, you know, the offense last year, we didn't do a lot of under center which is, you know, kind of a big thing. the foot work and play-action and just handing the ball off and just the little things. >> the terps will rely heavily on red shirt sophomore quarterback cj brown. there are still question marks surrounding his ability to lead the team but he is no spring chicken. >> people ask that a lot, you know, i've been preparing, you know, for this for a while. i got a little playing time last year and it's my opportunity. that's all you can ask. >> reporter: on the defensive side of the ball todd bradford is out and brian stewart is in. >> comes by way of houston where he was known for his three four defensive scheme which means there are changes on the way. >> for the most part everyone knows what to do and they're eager to learn how to do it correctly and fast. >> reporter: randy edsall remains and he is primed to win

some games. tomorrow's spring game will certainly begin to set the depth chart for fall season. but remember, these guys are in college, and there are added incentives at play. >> it'll be steak and lobster to the winners and beans and francs to the losers. i just want to see a continuation of guys getting better. >> there is a time when i thought beans and francs was a real treat. if that's what you get for losing must not be so bad. >> lobster. anything could happen. >> times have changed. >> a good point. we're softer now. >> yeah we are. coming up next on news 4 in our next half hour new details on what caused the dulles access road to be closed for five hours today. metro tries to fix its defibrillators after one of them didn't work during an emergency. a pig on the way to market ends up on a treadmill in a pool. the bizarre story you got to see.

says there are two general reasons for quick removal of dishes. one, a restaurant could be preparing for a second seating and, two, the server could be unskilled at reading the behavior of customers. for advice, let the server know when you sit down that you want to dine leisurely. we love it she says when people tell us what they want. at a crowded happy hour a couple spotted two free stools at the bar. one on either side of another couple. i asked if they could move over a seat a participant in my online discussion recalled the scene. they paused and started to pains takingly move their quack moleee. we left, frustrated our potential dining neighbors were reluctant to share the bar space. the questioner asked me for example the future, what is the correct way to handle this situation? well, don't give in so easily. anyone with any sense of propriety knows the gracious thing to do in such a situation is to just slide over to accommodate other customers. a bowl of guacamole isn't that hard to relocate. hesitant types might want to

>> our first question comes from sally in vienna, virginia. hey, sally says, liz, she plans to tackle piles of important papers for spring cleaning. which documents should she save and which can she toss? >> "consumer reports" helped us with this answer. it says to review anything from your bank immediately. hold on to anything needed for tax or financial reasons. you can toss your paid bills like credit card bills unless you need the bill to support a tax deduction. bank records that support your tax returns should be kept for seven years. that's because the government has up to six years to challenge your tax returns. you could be audited at any time if it suspects you of fraud. also, hold on to the essential records of course like birth certificates and social security cards. don't have to keep it all just so. no more excuses. >> next question from mike in winchester, virginia. >> okay. mike has heard that putting a small amount of acetone in your gas tank can increase your gas mileage. he wants to know if this is true. >> we contacted triple-a for the answer to this question. it does not recommend consumers

putting acetone in their gas tanks. sometimes the gas tank has a coating which acetone may be able to eat through which could cause serious problems for your car. instead, triple-a says do the simple stuff like making sure that your tires are properly inflated and keeping your trunk clear of unneeded items that weigh your car down. that will improve your gas mileage and keep the acetone for the nail polish remover. >> that's what it's for huh? okay. our last question comes through e-mail from a viewer named mary. mary wants to know why there are different colored lights on airplane wings. >> mary is paying attention. us airways helped us with the answer to this question and tells us that the lights on the wings of the airplane are simply called navigation lights from the pilot's perspective the red light is on the left wing tip. the green light is on the right one. the lights help outside observers determine which direction the plane is traveling. that makes sense. in addition those steady white lights by the tail of the plane simply help visibility from behind and the bright stroeb

light that constantly blinks helps the plane be more visible and attracts attention in the sky. if you have a question you'd like us to consider for ask liz send it to ask liz@nbc washington.com. connect with me on twitter and facebook by searching liz crenshaw and liz crenshaw's consumer watch. >> we want to know the direction the plane is going. >> what's on the left and what's on the right. is it going this way? >> have a great weekend. over to you. >> we take a look now at some of the stories trending online. doctors say too much coca-cola killed a new zealand mother of eight. 30-year-old natasha harris died in 2010. doctors say she regularly drank two gallons of coke every day. a hearing was held today in new zealand which is common for unexplained deaths. a doctor testified that she probably suffered from low potassium and toxic levels of caffeine. harris is also known for eating very little and for smoking 30 cigarettes a day.
