00:00:00Th adhd.
00:00:02Now up to nearly one in five high school-aged boys.
00:00:07Tonight a look at what might be driving these numbers.
00:00:09>>> High alert.
00:00:12As a chilling murder mystery unfolds in texas a top prosecutor and his wife targeted and killed in their home.
00:00:17Weeks after one of his top deputies was assassinated.
00:00:21>>> And in the driver's seat.
00:00:23For all those folks who want to keep driving and hang onto the car keys as late in life as possible, what doctors and scientists say you should be doing now to stay on the road later.
00:00:36>>> Also tonight, word that the most prominent living kennedy may be about to represent the u.s. overseas.
00:00:39"Nightly news" begins now.
00:00:44Captions paid for by nbc-universal television >>> good evening.
00:00:51In just the past few days the has flown over south korea with stealth bombers.
00:00:56Now they have sent stealth fighters and a guided missile destroyer.
00:01:01It's all because no one likes what they are hearing from north korea, the leader there.
00:01:06And no one knows what it means or how serious he is about his threats including the current declaration of a state of war.
00:01:13He's believed to be 28, 29 years old.
00:01:15He's young and untested.
00:01:16 defense secretary leon panetta said the must be prepared and very concerned because we cannot know kim jong un's motivations and intentions.
00:01:29 is going ahead with a military statement of its own tonight.
00:01:35Our chief foreign correspondent richard engel has reached seoul, south korea tonight and starts us off from there.
00:01:42>> Reporter: Good evening, brian.
00:01:43South korea thinks the north is bluffing, but pyongyang is playing a dangerous game of is matching with a show of force.
00:01:55 and south korean forces.
00:02:00A display of american f-22 stealth fighter jets.
00:02:04 navy destroyer prepared to shoot down a north korean missile if necessary.
00:02:09Overflights by b-2 stealth BOMBERS AND B-52s CAPABLE OF Carrying american nukes.
00:02:16An angry north korea released an animation showing the planes being shot down.
00:02:23In fact, if you watch north korean state tv, the country looks like it's at war.
00:02:32 soldiers used for target practice.
00:02:37Absolute leader kim jong un says he's put north korea's missiles at the ready calling his nuclear weapons the nation's life.
00:02:40Secretary of defense hagel calls the north belligerent.
00:02:45>> It has ratcheted up the danger.
00:02:51>> Reporter: South korea's president says she will respond to force with force.
00:02:56But it was calm here in seoul today.
00:02:58It's all bark, they say -- no bite.
00:03:01>> I really don't think people are thinking they are going to come actually attack us because, you know, america has our back.
00:03:10>> Reporter: Most people in seoul think the north is bluffing.
00:03:15The question is why.
00:03:16Experts say kim jong un is in the process of consolidating power and he's generating a crisis to whip his people up into a wartime patriotic frenzy so they will rally around the leader while he eliminates rivals.
00:03:30He's threatening war to clean house.
00:03:35There are big changes under way.
00:03:36Look at this video from late 2011, the funeral of kim's father, kim jong il.
00:03:41The hearse surrounded by his hand-picked successors.
00:03:44Since then nearly all have fallen from favor except kim jong un.
00:03:50The world's last stalinist state talking war to stay in power.
00:03:54Pyongyang's secrecy makes the old soviet kremlin look transparent.
00:03:56North korea appears to want to pick a fight.
00:03:59 says if it comes to that it's ready.
00:04:01Brian?
00:04:02>> Richard engel starting us off with what it's really like these days in seoul, south korea.
00:04:04Richard, thanks.
00:04:11>>> A stunning new assessment of national numbers came out today.
00:04:13It got the attention of a lot of us.
00:04:16It's about attention deficit, adhd and the extraordinary number of cases now being diagnosed.
00:04:27Like one in five high school age boys in the u.s.
00:04:3115% Of all school age boys.
00:04:3311% Of all kids in our nation.
00:04:34These numbers show a 16% rise in cases just since 2007.
00:04:40All of it is leading to questions about whether adhd is being overdiagnosed and whether the medicine to treat it is being overused.
00:04:46Our report tonight from our chief science correspondent robert bazell.
00:04:52>> Reporter: 14-Year-old ky and his 12-year-old brother kasen spend a lot of time outdoors staying as active as possible.
00:05:06The boys have a tough time sitting still.
00:05:08Both were diagnosed with adhd when they were younger.
00:05:10Their mom karen first noticed it when the boys had trouble completing simple homework assignments.
00:05:15>> It was such a struggle.
00:05:16We only got six problems done in one hour.
00:05:18In between that time, he just blurted out, he says, mommy, i can't think.
00:05:24I just can't think.
00:05:26>> Reporter: According to data collected by the cdc and analyzed by "the new york times," the number of children diagnosed with adhd is increasing.
00:05:37The times analysis shows an 4 million, ages 4 through 17, have adhd.
00:05:44Those numbers reflect a 50% increase in the past decade.
00:05:47Nearly two-thirds of those children get prescriptions with amphetamine-type drugs to help treat the disorder.
00:05:52Sales of the drugs reached $9 billion last year.
00:05:54>> I think this is of great concern.
00:05:55I think that there is some overdiagnosis and overtreatment going on under the guise of other conditions.
00:06:06>> Reporter: It's not just children diagnosed with adhd.
00:06:10On college campuses and high schools around america many students take the drugs to enhance performance on examinations.
00:06:18That raises many concerns.
00:06:18>> How is it acting on the brain in the long term?
00:06:20>> Reporter: Experts say there is no question that some children like the holmes have genuine problems that can be helped with medication.
00:06:28Many worry there is too much diagnosis and too much medication.
00:06:32Robert bazell, nbc news, new haven, connecticut.
00:06:35>>> There is fear and anger in kaufman county, texas, after the murder of a district attorney and his wife over the weekend.
00:06:41mike McLelland is the second prosecutor in the area killed in as many months.
00:06:47This comes in the wake of the murder of colorado's prison chief last month.
00:06:52Investigators say they are examining any and all leads.
00:06:55Gabe gutierrez is with us from kaufman county texas, tonight.
00:07:01Gabe, good evening.
00:07:01>> Reporter: Brian, good evening.
00:07:03According to a search warrant released this afternoon, police are looking at several things including -- and they say that and his wife were shot multiple times.
00:07:09They are now subpoenaing cell phone records looking for clues.
00:07:10So far there is no evidence to definitively link any of the murders.
00:07:14Today under the watchful eye of armed guards employees reported for work.
00:07:20>> Definitely concerned.
00:07:22>> Reporter: That concern comes as a manhunt is under way for a killer.
00:07:27DISTRICT ATTORNEY mike McLelland and his wife cynthia were found shot to death in their home saturday in what local officials call a brazen, targeted attack.
00:07:39Federal authorities tell nbc 22 caliber shell casings found in the house.
00:07:46>> We are very much on alert.
00:07:47We have folks out to do harm to elected officials.
00:07:50So we take it very seriously.
00:07:51>> Reporter: Two months ago the was gunned down outside the courthouse.
00:07:59AT THE time McLelland had this promise for the killer of mark hasse.
00:08:03>> We are very confident that we are going to find you.
00:08:08We are going to pull you out of whatever hole you're in.
00:08:10We are going to bring you back and let the people prosecute you to the fullest extent of the law.
00:08:19>> Reporter: Mclelland told friends he carried a gun everywhere and was extra careful when answering his door.
00:08:26Investigators have been working to see if hasse's shooting was connected to the killing of colorado's prison chief last month.
00:08:33The suspect in that case who later died in a police shootout in north texas was linked to a white supremacist group.
00:08:40Months before, texas investigators issued a warning about the aryan brotherhood of texas planning retaliation against public officials.
00:08:51Although federal sources tell nbc news they have yet to find a solid connection between the murders.
00:08:55In the meantime, texas governor rick perry is urging caution.
00:08:58>> I suggest everyone should be careful about what goes on whether they are public officials or otherwise.
00:09:03>> Reporter: And this small county outside dallas is in mourning and on edge.
00:09:07Meanwhile, federal law enforcement officials tell nbc news they are not ruling out anything from the white supremacist group to a drug cartel to a lone gunman with a grudge.
00:09:19Meanwhile a new interim d.a.
00:09:20Took over the office this afternoon.
00:09:24Brian?

00:09:27Gabe, thanks.
00:09:28>>> The movie theater shooting spree in aurora, colorado, is back in the news tonight.
00:09:31It left 12 dead, another 58 wounded last july.
00:09:36Prosecutors today said they will seek the death penalty for the accused gunman, james holmes.
00:09:42Nbc's miguel almaguer covering for us tonight.
00:09:47Miguel, good evening.
00:09:49>> Reporter: Brian, good evening.
00:09:51It was a dramatic and emotional day inside the courtroom where victims embraced and others wept as the prosecutor made his announcement.
00:09:59James holmes had no visible announced for james egan holmes justice is death.
00:10:05This after prosecutors rejected a plea deal that would have led to a guilty plea but spared holmes from the death penalty.
00:10:15Accused of murdering 12 and injuring dozens last summer inside an aurora movie theater, holmes's lawyers will pursue an insanity plea.
00:10:22The victims were split.
00:10:28 should have accepted the plea deal.
00:10:30Others think holmes should face death for his accused crimes.
00:10:32Brian?
00:10:33>> Miguel almaguer covering for us from centennial, colorado, tonight.
00:10:39Miguel, thanks.
00:10:39>>> The latest from south africa is nelson mandela is improving.
00:10:41He spent a sixth day in the hospital and continues to respond to treatment for the lung condition.
00:10:45The nation and millions around the world, of course, have been in suspended animation over worry for the president.
00:10:53He's now been hospitalized three times in the past four months.
00:10:55>>> While the white house is cautioning nothing is final, no formal nomination has been made reports have surfaced that caroline kennedy is being vetted for u.s. ambassador to japan.
00:11:15Just hearing that was enough to cause americans of a certain age to reflect today on a life lived largely in the public eye.
00:11:19Our report tonight from nbc's andrea mitchell.
00:11:20>> Reporter: The world first met her as a 3-year-old in a storybook white house.
00:11:28A toddler interrupting her father in the oval office.
00:11:30With her brother and their picture perfect parents the first family became america's symbolic ambassadors to the world.
00:11:38Until her childhood was interrupted by tragedy, forever reminding us of heartbreak.
00:11:41Like her mother, intensely private, caroline was still a kennedy.
00:11:44The question of her role became inevitable.
00:11:45>> Has the torch been passed to caroline kennedy for future public service?
00:11:51>> Oh, I don't -- well, I hope.
00:11:52I think there are many ways to serve.
00:11:53My uncle sets a tremendous example.
00:11:58>> Reporter: In 2008 at the height of the obama-clinton primary battle she jumped into the fray, comparing obama to her father.
00:12:13>> Fortunately there is one candidate who offers the same sense of hope and inspiration.
00:12:20Kennedy to the podium.
00:12:20>> Reporter: Led to a brief exploration of running for the senate to replace hillary clinton.
00:12:25Elective office not a natural fit for this kennedy.
00:12:26But diplomacy, her grandfather was ambassador to great britain before world war ii.
00:12:31Her aunt jean was bill clinton's ambassador to ireland.
00:12:34Half a century after her father's assassination with her brother, uncle and mother now gone, caroline kennedy is ready to serve, most likely in japan, a country that loves political names like former vice president walterer mondale.
00:12:54>> Sending someone who has such high visibility, almost standing as a kind of celebrity, I think, gives her cache the minute she lands in tokyo.
00:13:04>> Reporter: Kennedy would have to be confirmed by the senate but experts say she's a lot more qualified than many ambassadors appointed only because of the size of their campaign wallet.
00:13:16Andrea mitchell, nbc news, washington.
00:13:17>>> Still ahead for us as we continue on this post easter monday night, the difficult conversation in millions of american families.

00:15:39>>> We have said this before.
00:15:40It's one of those bad conversations.
00:15:41The moment many seniors have come to dread when family members approach to take away the car keys, ending a life of driving and usually under protest.
00:15:57The news on this tonight is this.
00:15:58 is are researching ways to buy insurance time earlier in life to stay behind the wheel later in life.
00:16:01Our report tonight from nbc's stephanie gosk.
00:16:06>> Reporter: For a 72-year-old guy, stanton lyman has some good moves.
00:16:12The architect obsesses over two things -- his health, and his cars.
00:16:22What he didn't know until recently is if he keeps up the exercise he may be able to drive the cars longer and more safely.
00:16:27>> We know flexibility, coordination, strength, those issues are related to yielding, changing lanes, backing up which become increasingly difficult as you age.
00:16:40>> Reporter: With funding help from the hartford insurance 's age lab conducted a study of drivers 60 to 74 years old, including mr.
00:16:45Lyman to test the theory.
00:16:46>> Look at the speedometer please.
00:16:48>> Reporter: For ten weeks they used video games to focus on range of motion, coordination, and strength.
00:16:56They were then tested in the lab using this high tech simulator measuring reflexes, pulse rate, and eye movements.
00:17:06>> The study taught me to stretch and to move.
00:17:08And to move my body.
00:17:09Clearly that's had an effect.

00:17:29>> Researchers say drivers in THEIR 30s AND 40s SHOULD START Thinking about flexibility now because it can help with tricky moves like parallel parking and some of us could definitely use the help.
00:17:42The point is for drivers to take responsibility for the safety of their driving at an earlier age.
00:17:48>> Driving is not about getting from point a to point b.
00:17:50It's about life.
00:17:51It's the glue that holds all those big and little things together.
