In the summer of 1994, in Tulsa, Okla., Brandy Carpenter, then 14, had just started dating her crush, 17-year-old De'Marchoe Carpenter.

But before they even had their first kiss, De'Marchoe was arrested for a murder he didn't commit.

At StoryCorps in May, De'Marchoe, 41, and Brandy, 38, remember what first drew them to each other, and the toll that prison took on their relationship.

"You always made me laugh and you always made me smile," Brandy says. "I always wanted you to be around."

On Sunday, Colombia elected a new president, Ivan Duque, a conservative former senator who's pledged to rewrite a divisive peace treaty that ended the country's 50-year-old guerrilla war.

In the second and final round of elections, Duque won 54 percent of the vote, defeating former guerrilla fighter and onetime Bogota Mayor Gustavo Petro, 58, who captured about 42 percent in the runoff. Duque will succeed outgoing President Juan Manuel Santos.

Infamous photographs, taken seconds after Sen. Robert F. Kennedy was shot on June 5, 1968, show him lying on the floor of the Ambassador Hotel's kitchen. A teenage busboy kneels beside him, cradling the senator's head.

That busboy was Juan Romero.

Kennedy was running for president and had just won the California Democratic primary when he was assassinated at the Los Angeles hotel.

Dense fog and a soggy track blurred ideal viewing conditions, but there was no mistaking Justify's run to victory in the 143rd running of the Preakness Stakes at Pimlico Race Course in Baltimore.

Kittie Weston-Knauer, on the cusp of 70 years old, is the oldest female BMX bicycle racer in the U.S.

When she started competing in the late 1980s, she was often the only woman on the track. It was her son, Max Knauer, a champion BMX rider, who introduced her to the sport when he was 10.

Max, now 40, explains that he planted the racing seed after a frustrating day of his mom playing coach.

A new exhibit that opens Monday at the United States Holocaust Memorial Museum aims to honor a founding mission.

Five years in the making, "Americans and the Holocaust" contextualizes attitudes in the U.S. during 1930s and '40s persecution and mass murder of Jews in Europe.

Twenty-five years ago, when the building opened, noted Holocaust survivor Elie Wiesel introduced the museum not as an answer to the horrors of genocide but to pose a glaring question: How could this happen?

Roxanne and Dennis Simmonds knew their son as fearless and strong from the day he was born.

"D.J. came out with shoulders of a linebacker," Roxanne says. "He was the first baby I saw that had muscles."

"He wasn't really afraid of anything," Dennis says.

At night, young D.J. would take the dog with him and circle the entire house, to "make sure there's nobody on the grounds," Dennis says, laughing. "I used to say, 'D.J. where you going? It's late.' He would say 'I'm doing a perimeter search, Dad.' "

Brothers Russell, 28, and Remmick Wadsworth, 27, have autism. As kids, they had trouble with social interactions, so they often relied on each other for support during tough situations. Now, as the siblings navigate the working world, they're still looking out for each other.

Remmick remembers his first job, working with his older brother in a coffee shop. "You would always have my back, talking to customers for me, handle them for me while I make their drinks," he tells Russell during a StoryCorps conversation.
