The hour-long report will air Monday, July 26 (10:00 PM/ET).

Below are excerpts.

On Kaine Horman reacts to hearing about the murder-for-hire plot that his wife Terri allegedly hatched to try to kill him before Kyron went missing:
KATE SNOW: You've been informed that she was trying to hire someone to murder you.

KAINE HORMAN: I didn't believe it at first. It was something that I couldn't even wrap my head around at the time--

SNOW: There'd been no indication in your marriage--

KAINE HORMAN: No.

SNOW: --that things were that bad or that she was upset with you.

KAINE HORMAN: No.

SNOW: Do you fear for your safety now, Kaine? For your daughter?

KAINE HORMAN: I fear for my daughter.

SNOW: Do you think she is capable of hurting a child?

KAINE HORMAN: If you asked me before this situation, my answer's no. Based on what I know now, I don't know.

KAINE HORMAN: I think anything is possible, based on the way things have gone over the past few weeks.

On Desiree's husband Tony says that as early as the first night of the investigation, the very day Kyron went missing, he explained to the family what to expect from detectives. Tony expresses surprise at Terri Horman's reaction:
TONY YOUNG: I explained to each person that now our lives are not private anymore, that the investigators are going to want to know very detailed information about our lives ...

TONY YOUNG: She instantly started to express some displeasure at that and not wanting -- feeling like she was persecuted. And I thought that was kind of an unusual reaction that early.

Tony reveals to "Dateline" that the police asked Terri Horman to submit to a polygraph more than once:
TONY YOUNG: I thought something must not be right. Something must not be allowing them to check her off the list.

KATE SNOW: Is it possible, though, that she was just nervous, that she didn't pass her lie detector test with flying colors because she was emotional or upset or--

TONY YOUNG: There's more to it than just that... The information that you're giving, does it does it hit your ear and sound right? Does it make sense?

KATE SNOW: She wasn't making sense?
TONY YOUNG: Not from the information I heard from her.

On Kyron's mother, Desiree Young, in Kyron's bedroom that she's left just as it was the last day Kyron was there:
DESIREE YOUNG: His bed I still can't bring myself to make it. It's the same as it was when he last slept in it. And I can't put away his laundry. His cars are still out -- he was playing with his little car wash last time he was here.

What did you think of the case? Should police be allowed to threaten and lie to witnesses during questioning -- telling them they have eyewitnesses to a crime or that someone has confessed? Do you think police lies and threats of prison can cause a person to falsely accuse another? Share your thoughts by leaving a comment below.

The full report will be viewable online tomorrow, Saturday.

You’ve all seen him by now. Kyron Horman. He is the cute little guy in glasses, standing in front of his science fair project on the red-eyed tree frog. He’s clearly so proud of himself. That picture was taken on the last day anyone saw Kyron. It was June 4th—seven weeks ago.

When I first met Kyron’s biological parents—Kaine Horman and Desiree Young— a couple of weeks ago, I was struck by how composed they were.

They had been through so much already. They seemed drained and deeply worried but also determined.

They told me they had turned a corner.

“I think I’ve moved past the sad, depressed all the time, crying nonstop-- to anger and frustration and dedication,” Desiree told me.

"It’s hard. I think we’re pretty much in the same place. It is—just that relentless focus to find him that, you know, drives us every day,” Kaine said.

I’m new to the Dateline NBC family so if you’re a die-hard NBC fan, you may not be familiar with my work. Over the years, I’ve been proud to cover a wide-range of stories that hopefully had an impact.

But the stories that stick with me forever are the stories that touch me as a parent.

I am the mother of two beautiful kids. I have a seven-year-old son. So when my new bosses asked me to travel to Portland, Oregon and meet with the parents of seven-year-old Kyron Horman I knew it would be a tough assignment. As parents, we all know intellectually that these are rare cases, but we can so easily imagine ourselves in the same position. The panic we would feel. The desperation.

Kyron’s elementary school was gracious enough to allow us inside to see his classroom. It is a beautiful old school, a throwback to a simpler time. There are little gardens planted by the children outside. The other day a few mothers were outside clearing away the weeds as summer vacation rolls on.

Kyron’s entire graduating class is just 26 kids. It’s the kind of rural community where everyone knows everyone.

I was struck by what a pretty area it is. There are rolling hills and old red barns next to vineyards and big swaths of tall pines.

Kyron’s parents are convinced that someone in that community knows where Kyron is. They want us to air an hour on "Dateline" because they hope it might help jar a memory, or convince someone to speak up. They’re convinced that Kyron is still alive. And with all my heart, I hope they’re right.

A teen loses his life to a bullet during a Saturday night party in a small town – and his friend loses his freedom to what he says is a lie. Dennis Murphy reports.

Family and friends go to extraordinary lengths to honor a legacy of a young man whose trust led to tragedy. Keith Morrison reports. Airs Friday, 9 p.m./8 CT

For some this economy may be turning around but the reality is millions of families are at risk of going hungry, in one of the richest nations on earth. In the past two years alone, the number of Americans visiting food pantries has jumped 30 percent. Over the last nine months, "Dateline" focused its cameras on how the Great Recession has impacted some of the poorest people in America – those who are the first to feel the downturn, and will likely be the last to feel the recovery.

For the report, "America Now: Friends & Neighbors," airing on Sunday, July 25 (7:00 PM/ET), "Dateline" anchor Ann Curry travels to Ohio where the hardworking poor, with deep traditions in mining, manufacturing and military service, are increasingly seen in food pantry lines ashamed and angry. Recently, the people of Southeast Ohio made pleas for jobs and food written on thousands of paper plates to President Obama. One message reads: "My husband worked hard all his life and he died hungry." Curry interviews people struggling with poverty and unemployment, and reports on what they're doing to make their lives, and their children's lives, better.

Their stories, and the images, push beyond stereotypes and reveal a hidden America that is both surprising and haunting but nevertheless, hopeful. While most television news reporting on the recession has focused on those with a voice and influence -- the middle class -- this hour-long look at how the recession has affected America's poor is a rare chance for viewers to get a comprehensive look at what poverty looks like over time in the heartland.

Viewers will hear from a woman who despite being poor herself, opened a food pantry, "Friends & Neighbors," that feeds thousands; a young mother who spent Ohio's cold month of November sleeping in a van with her children ages 1, 2 and 3; an extended family of 14 crowded into a 4-bedroom house to survive; and a father who was laid off and unable to pay for heat so he woke every two hours to feed the woodstove to keep his two young sons warm.

When someone goes missing, one of the hardest things for those left behind is never knowing the truth. Did their loved one escape to a new life? Or did something terrible happen to them? Are they dead? Or alive?
The three children in tonight's story arrived home one evening to discover their mother was missing. But for them, the truth of what really happened may have been the hardest thing of all. Keith Morrison with The Disappearance of Debbie Hawk, at 10 p/ 9 C on Dateline.

Monday's mystery looks into the murder of 28-year-old Melissa Mooney, who was discovered dead in her home in August 1999. The FBI spent years trying to find the murderer because Melissa was one of their own -- she worked for the FBI in Wilmington North Carolina as an office manager. Correspondent Josh Mankiewicz interviews the FBI agents who wouldn't give up trying to get justice for Melissa and reports on the ending that surprised them all.

For the FBI agents you'll meet tonight, fighting crime is a way of life but when their own office manager, a young women they felt was family, was murdered, their professional mission became very personal.

They faced a complicated investigation that eventually became not just about getting justice for one of their own...but for a string of -other- women, who'd maybe been too afraid to seek it for themselves.

Josh Mankiewicz with The Mystery on Reminisce Road, at 10, 9 central on Dateline.

It's a story with all the intrigue, lies, and betrayal of a Cold War thriller: Secret codes, forged passports, invisible ink, and a real-life femme fatale. But this great power drama unfolded in just the last two weeks -- the biggest spy swap in a generation. Ten "deep cover" agents for Russia, swept up from leafy American suburbs and city streets and hustled back to Moscow, exchanged for four people convicted of spying for the West. Now, we take you -inside- this 21st century version of From Russia with Love. Dateline correspondent Dennis Murphy is on the trail of "The Spies Next Door."

Saul Kassin is a Distinguished Professor of Psychology at the John Jay College of Criminal Justice, Massachusetts Professor of Psychology at Williams College, and Past President of the American Psychology-Law Society. He is a national recognized expert on the psychology of false confessions. Dr. Kassin was a defense witness at the trial of Billy Wayne Cope.

In criminal law, confession evidence is incredibly persuasive—yet it’s fallible. Despite the pervasive myth that people do not confess to crimes they did not commit, the pages of American history, beginning with the Salem witch trials of 1692, pay homage to all the men and women who were wrongfully convicted and imprisoned, often because of false confessions. No one knows the precise extent of the problem; research shows that false confessions to police were a contributing factor in 25% of cases in which innocent prisoners were exonerated by DNA.

There are three types of false confessions: Voluntary, compliant, and internalized.

Voluntary false confessions are those in which people step forward to claim responsibility for crimes they did not commit without prompting from police. Often this occurs in high profile cases—as when John Mark Karr in 2006 confessed to the unsolved murder of young JonBenet Ramsey. There are several reasons why innocent people volunteer confessions—such as a pathological need for attention, or self-punishment; feelings of guilt or delusions; the perception of tangible gain; or the desire to protect someone else.

In contrast, innocent people are sometimes induced to confess through the processes of police interrogation. In compliant false confessions, the innocent suspect acquiesces in order to escape from a stressful situation, avoid punishment, or gain a promised or implied reward. In these cases, basically, the confession is an act of compliance by a suspect who comes to believe that the short-term benefits of confession outweigh the long-term costs. This phenomenon was dramatically illustrated in the 1989 Central Park jogger case, where five New York City teenagers confessed after lengthy interrogations, each claiming he expected to go home afterward. All the boys were convicted and sent to prison, only to be exonerated in 2002 when the real rapist gave a confession that was confirmed by DNA evidence.

Third, internalized false confessions are those in which innocent but vulnerable suspects, exposed to highly suggestive interrogation tactics, not only confess but come to believe they committed the crime in question. The case of 14-year-old Michael Crowe, whose sister was stabbed to death, illustrates this phenomenon. After lengthy interrogations, during which time Michael was misled into thinking there was blood, hair, and other physical evidence of his guilt, he concluded that he was a killer: "I'm not sure how I did it. All I know is I did it." Eventually, he was convinced that he had a split personality—that “bad Michael” acted out of jealous rage while "good Michael" blocked the incident from consciousness. The charges against Crowe were later dropped when a drifter from the neighborhood was found with his sister’s blood on his clothing.

Inspired by tales of innocents wrongfully convicted, many psychologists have used scientific research methods to study the causes and consequences of false confessions. This research shows that some types of people are more vulnerable than others; that certain interrogation tactics can substantially increase that risk; and that police, juries, and others are not particularly good at judging confession evidence in court.

For more information, Saul Kassin’s web site contains a number of relevant news and research articles, links, blogs, and other useful information on the subject: http://www.williams.edu/Psychology/Faculty/Kassin/index.html.

On Sunday, July 18 at 7:00PM ET, Dateline will air its year-long investigation into children migrant workers, reported by Dennis Murphy.

While the Department of Labor has made eliminating underage child labor a top priority and has hired 250 more investigators to be out on the fields this summer enforcing stiffer fines for farmers allowing children under 12 to work, agriculture has always been an exception to the rule when it comes to minimum age and the workplace. At twelve, a child can pick blueberries all day long in the hot sun, but at twelve, he's still too young to get a job stocking those berries in an air-conditioned supermarket. It's an unfair irony that is the reality for those children of migrant workers who live in the world of "Don’t ask, don’t tell."

"America Now: Children of the Harvest," airing on Sunday, July 18 (7:00-8:00 PM/ET), is a year-long investigation that takes viewers into the lives that belong to the invisible hands in America’s bounty -- migrant farm workers who travel with their families to pick the fruits and vegetables that go on our table. Beginning in the spring of 2009, Dateline went back to the fields to follow up on its Emmy-award-winning 1998 story that followed migrant families from Texas. We wanted to know: Were kids under the age of 12 still doing backbreaking illegal work at the start of the 21st century, and would we be surprised by how those children we followed in 1998 are doing now?

The documentary intimately follows the journey of ten-year-old Ulysses Cruz, a young boy whose life has been dictated by the cycle of the crops, and NBC News cameras document children under 12 doing work in agriculture forbidden by child labor laws. In addition, Dateline correspondent Dennis Murphy interviews Carl Fillichio of the Department of Labor and Zama Coursen Neff of the non-governmental advocacy group Human Rights Watch about our findings and to see what is being done to protect these children.

"Children of the Harvest," is the third installment of America Now series that examines issues facing Americans today and how communities across the country are doing in these adverse times.
