and all passengers were off loaded by 7:21. i would say it was a full six- car train so there were just under 1,000 passengers on board the train. >> reporter: the trains kept running, looked pretty full, but single tracking to get around the derailment caused some delays. >> i had to wait for the orange train to go by, because of the single track, and then wait for the orange train to unload before we could move to the next stop. >> you know, i didn't wait but about 15 minutes. it wasn't too bad, and the train wasn't too crowded, but it was sufficiently late to make me wait for something i wanted to do. to get to the hardware store before it closed. and delays on the platform. >> probably 20 minutes. the train just came, i'm happy, it's all good. >> but what about morning rush? >> crews are going to be working throughout the night and as long as they need to do our best to ensure morning rush hour will not be affected by this. >> reporter: a few moments ago, she seemed optimistic, but remember what she said. 1,000 passengers on that one

train alone. if this thing isn't out of the way by morning, it could affect tens of thousands of commuters here. my bosses would want me to tell you this. we're on the air at 4:25. 9 news now begins at 4:25. they'll have that current information up-to-the-minute. check it out then. if anything happens between now then, we'll tell you. >> great advice, gary nurenberg, thank you for that. new at 11:00, police on the scene of a homicide investigation. this one in district heights maryland. sky 9 out over the scene just awhile ago. detectives say an adult male was shot to death. we don't have any word on a motive. and police also out there on the scene of a homicide investigation in northwest d.c. this body was found at 800 emerson street, but police are not releasing any other information. five people are dead tonight, poise oned by -- poisoned by carbon monoxide. investigators say a broken exhaust pipe in a furnace allowed the carbon monoxide to

escape into the home. >> we had a heating system that had a very little piping system. it obviously had not been maintained. >> prince georges fire chief, mike brady, says the amount of carbon monoxide found in the home could have proven fatal in just an hour or two. an 85-year-old woman dies in police custody and now detectives are trying to figure out what happened to her. it started early this morning. the woman apparently had been acting irrationally at the hospital. police were called in. they placed mary gene martin in the back of a patrol car andattempted to take her to a mental facility for evaluation. that's when martin went into some sort of melodies trees and a-- medical distress and attempts to save here were unsuccessful. this woman was caught trying to smuggle cocaine. but she isn't facing charges. she arrived on a flight from el salvador. customs found six chocolate bars with a cocaine center as

well as six small drink boxes with cocaine inside. this woman was identified as a quote, unquote, legitimate currier. she was not criminally charged. instead she faces a five-year ban from entering the united states. five states held their republicans and mitt romney poised to make a clean sweep. cbs's danielle nottingham with more from the white house.

[ cheers and applause ] >> reporter: romney thanked supporters in a speech titled a better america begins tonight,

in which he focused his criticism on president obama. >> four years ago, barack obama dazzled us in front of greek columns with sweeping promises of hope and change. but after we came down-to- earth, after all the celebration andthe parades, what do we have to show for 3 1/2 years of president obama? >> reporter: president obama's re-election campaign has been ramping up for months. while his republican rival hadn't been named officially, the president is getting more comfortable talking about mitt romney. he joked about him with late night talk show host jimmy fallon. >> do you know mitt romney? >> i've met him, but we're not friends. >> reporter: newt gingrich was counting on a win in delaware to keep his campaign alive. >> we have, i think, 23 events all together here in north carolina this week. we are going to be at 23 events here in north carolina this week. >> reporter: he is vowing to

back to their hotel rooms, secret service director mark sullivan was on capitol hill today trying to ensure congress that the matter was being dealt with swiftly, fairly and comprehensively. >> i give mark solomon a tremendous amount of credit. >> reporter: he said he believes the secret service's internal investigation has been handled well so far, but he's still staggered by the reckless behavior of the 12 agents in question. >> this could have involved national security, it could have compromised national security. why these men put the president potentially at risk, put their careers at risk is absolutely beyond me. >> reporter: while congressman king expressed full confidence in the secret service's internal investigation, he said he had serious questions about the white house's investigation of the possible involvement of white house staffers in the prostitution scandal. >> the white house counsel's office has conducted a review. >> reporter: according to white house press secretary jay carney that review is now

complete and no white house staffers were found to have done anything wrong. >> i would have thought that since anything could have happened down there, that before the white house come out and so categorically said there was no involvement, i'm really wondering what the extent of their investigation was. >> reporter: keep in mind, there's still a third investigation into the prostitution scandal. the u.s. defense department is now looking into the possible role of about a dozen members of the military. derek? >> matt jablow, thank you. a warning tonight about crooks on the prowl trying to take advantage of unsuspecting home owners. the frederick county sheriff's office is reminding people be on the lookout for scammers looking to do home improvement work like driveway sealing, chill my repair or hot tar roofing. that warning after three reports of crooks offering to seal driveways at a discounted price, but the price much higher than what a normal contractor would charge. investigators say the scammers were most likely ask to be paid in advance in cash and may be

hesitant to offer any credentials. alarming, yes, but no need to panic say government officials who are confirming the first case of mad cow disease since 2006. our ken molestina explains how it was picked up and why the usda says humans are not in danger. >> reporter: the disease was found in a dead 5-year-old cow taken here to a plant in california. it was about to be ground into pet food when a random test discovered the illness. officials are sure there was never a danger to humans from the cow's meat or milk because according to veterinarian john clifford, no dead cow is ever slaughtered for human consumption. >> this particular animal did not enter the food supply at any time, so there is no concern about that. >> reporter: the diagnosis is bovine spongy form, spontaneous and not known to be contagious to humans or animals. atypical means it did not get

sick from other cows or eating feed composed of other animals. >> it is not likely to be attributable to infected feed, which is the method in which normally bse would be spread from cow to cow. >> reporter: three americans are thought to have died from mad cow disease, a brain- wasting infection with no cure. but all three spent many years eating beef overseas. no american has been known to die from consuming u.s. beef since increased testing was begun. two concerns tonight. beef exporters in the u.s. are worried that consumers in asia are going to hear the term mad cow and become scared and therefore the purchase of u.s. beef will be slowed. and the second one is although the atypical form of this disease is not going to be a problem, we still don't know what causes it. we're in the satellite center, ken molestina, 9 news now. new tonight, the alzheimer's association presents one of its major
