Some murder cases are harder to solve than others. The investigation into the killing of Mellory Manning — a 27-year-old woman who was assaulted and murdered in 2008 while working as a prostitute in Christchurch, New Zealand — confounded police.

They conducted an investigation and interviewed hundreds of people, but months later, they still had no solid leads.

Victorine Meurent was just 17 years old when she met the great Impressionist painter Edouard Manet on a Paris street in 1862. The young, poverty-stricken redhead became his favorite model, and Manet painted her reclining nude in Olympia — a work that scandalized the Paris art world in 1865 and now hangs in the Musée d'Orsay.

The tragic story of Cambodia in the '60s and '70s is well-known: It became engulfed in the Vietnam War, then more than a million Cambodians died under the Khmer Rouge regime. Doctors, lawyers, teachers — educated people — were targeted in the communist takeover. So were artists and singers.

The death penalty is legal in more than 30 states, but the long-controversial practice has come under renewed scrutiny after a series of botched executions in several states last year.

Opponents of capital punishment argue that the death penalty undermines the fair administration of justice, as wealth, geography, race and quality of legal representation all come into play, with uneven results.

Jazz musician and composer Charles Lloyd has what you might call an "eclectic" resume.

The saxophonist has played with hundreds of jazz musicians — but also B.B. King, the Beach Boys, tabla master Zakir Hussain.

Tonight, Charles Lloyd will be inducted as a National Endowment for the Arts Jazz Master. He's being honored, in part, for fusing jazz with musical styles from other places and times.

You can hear that on his new album, Wild Man Dance, which features two ancient instruments from Europe.

Martin O'Malley, former governor of Maryland, says he'll decide by late May whether he's running for president. Running would put him — even he seems to acknowledge — in an uphill battle against Hillary Clinton, currently the only Democrat who has declared.

O'Malley is positioning himself to Clinton's left, and even President Obama's left.

Aydian Dowling of Eugene, Ore., is ripped. He has sharply defined muscles, piercing eyes and European-playboy-on-the-Riviera tousled hair.

It's not just striking good looks that distinguish Dowling, who is leading the voting in the annual "Ultimate Guy" contest held by Men's Health magazine. If he wins the contest (which is ultimately determined by judges), Dowling will be the first transgender man to appear on the cover of Men's Health.

Here's a quotation about prison overcrowding: "All research and successful drug policies show that treatment should be increased and law enforcement decreased, while abolishing mandatory minimum sentences." That's not from some stodgy think tank. That's metal.

A town that experiences a sudden suicide epidemic, a mysterious traveling salesman who sells a magical mirror polish, a mermaid who washes up on shore: What happens to a small town when something strange and supernatural takes over?

Pulitzer Prize-winning author Steven Millhauser explores that intersection of familiar life and disturbing, often bizarre events in his new short story collection, Voices in the Night.

A mountain lion was holed up under a house in Los Angeles for a little while last week, making headlines across the country.

But the puma, known as P-22, was already pretty famous. He's got his own Facebook fan page with more than 2,000 likes, plus a couple of Twitter accounts.

His range is the 8 square miles of LA's Griffith Park, on the eastern edge of the Santa Monica Mountains, surrounded on all sides by development.

The class of 2015 is nearing graduation. For students at Howard University in Washington, D.C., that day is May 9.

Seniors are excited — and they are getting antsy.

NPR's Weekend Edition has been following four of those seniors all semester: Taylor Davis, Ariel Alford, Kevin Peterman, and Leighton Watson.

This week, the four joined NPR's Rachel Martin in our D.C. studios to talk about the songs that have formed the soundtrack to their college years.

Step aside, home chefs! The kitchen of the future draws near.

No, there's no hydrator from Marty McFly's kitchen in Back to the Future II. Right now, the chef of the future looks like a pair of robotic arms that descend from the ceiling of a very organized kitchen. And it makes a mean crab bisque.

Netflix's original series now have a superhero among them. Comic fans know Daredevil as a crusader. He's a Marvel character who, in addition to his superhuman abilities, has a very human disability: blindness.

Needless to say, Daredevil has quite a few fans with visual impairments — and they were looking forward to the show.

But until this week, Netflix had no plans to provide the audio assistance that could have helped those fans follow the show.

The culinary world lost a visionary this week. Homaro Cantu, a specialist in the avant-garde approach to cooking known as molecular gastronomy, died Tuesday in Chicago at the age of 38. The Cook County Medical Examiner ruled Cantu's death a suicide.

Every visit to Cantu's flagship restaurant, Michelin-starred Moto, was a trip down the rabbit hole.

Advertisements don't need any words to say a lot about a culture.

That's one of the messages that shines through in the work of artist Hank Willis Thomas. In 2008, Thomas removed the text and branding from ads featuring African-Americans, creating a series he called Unbranded, which illustrated how America has seen and continues to see black people.

The World Bank's goal is to end extreme poverty and to grow income for the poorest people on the planet.

The bank does this by lending money and giving grants to governments and private corporations in some of the least developed places on the planet. For example, money goes to preserving land, building dams and creating health care systems.

When the U.S. withdrew its troops from Iraq in 2011, many American news organizations followed suit, scaling back or shutting down their bureaus. Ned Parker was among a handful of American journalists who continued to report from the country.

John Wilkes Booth was the man who pulled the trigger, capping off a coordinated plot to murder President Abraham Lincoln.

But historian Terry Alford, an expert on all things Booth, says that there's much more to Booth's life. His new biography, Fortune's Fool: The Life of John Wilkes Booth, delves deep into his life — before Booth went down in history as the man who assassinated a president.

When Henry Paulson first visited Beijing in 1991 as a banker, cars still shared major roads with horses.

"I remember getting into a taxi that drove too fast on a two-lane highway ... [that was] clogged with bicycles and horses pulling carts," says the former secretary of treasury under George W. Bush. "You still saw the hutongs — the old neighborhoods [with narrow streets] — which were very, very colorful and an important part of life."

The day after Japan surrendered in 1945, and World War II ended, singer Bing Crosby appeared on the radio program Command Performance. "Well it looks like this is it," he said. "What can you say at a time like this? You can't throw your skimmer in the air — that's for a run-of-the-mill holiday. I guess all anybody can do is thank God it's over."

New York Times columnist David Brooks cites this and other aspects of that 70-year-old radio program as evidence that America once marked triumph without boasting.

Tina Packer has spent a lifetime researching Shakespeare and his plays, both as an actress and as a director. And as she focused on the role that women play in his works, she noticed a progression.

Consider Shakespeare's Taming of the Shrew, one of his earliest plays, which centers on a man breaking a defiant woman's spirit. Strong-willed Kate is a harridan; her compliant sister, meanwhile, says things like, "Sir, to your pleasure humbly I subscribe."

For decades, the story of Hannah Reynolds' death read like a tragedy of historical circumstance.

In 1865, Reynolds was a slave in the household of Samuel Coleman in the Virginia village of Appomattox Court House. And as Union and Confederate troops fought the Battle of Appomattox Court House on April 9, 1865, a cannonball tore through the Coleman house.

The Coleman family had left the day before, but Reynolds had stayed behind. The cannonball struck her in the arm and, it was thought, she died that same day, as the battle's only civilian casualty.

When English journalist Graham Holliday got tired of his office job in the U.K., he knew he wanted a change — a big one.

So he packed up and moved to Asia, first to Korea to teach English and ultimately, to the place that would be his home for nine years: Vietnam. As soon as he arrived, he was determined to immerse himself in Vietnamese culture — and for him, that meant food.

Businessman Mokhtar Alkhanshali was used to the complications of traveling to Yemen. He'd been traveling there and back for years; sometimes the American Embassy would close for a few days amid turmoil, but it always opened back up.

But on March 27, the situation changed dramatically. "Overnight, the country went to war," he says.

The Yemeni-American coffee importer had been in Sana'a, Yemen's capital, on business when the city was rocked by explosions. He stepped outside at 2 a.m. to find anti-aircraft guns lighting up the night sky.

There's not a whole lot to do in prison, so inmates spend a fair amount of time playing cards.

For several years, law enforcement officials around the country have been putting that prisoners' pastime to good use. They've been putting facts and photos from unsolved crimes in front of prisoners' eyes by printing them on decks of cards, hoping to generate leads.
