Seventy-five years ago, Key Underwood and his raccoon-hunting dog Troop had a connection. Years of training and a deep relationship make human and canine a seamless hunting unit. The two can share a special bond.

So when old Troop died, Underwood buried him on the crest of a hill hidden away in the lush countryside near Cherokee, Ala. It was Underwood's favorite hunting spot. He marked the grave with an old chimney stone he chiseled with a hammer and screwdriver.

In 2010, NPR reported that some Army commanders refused to award the Purple Heart to many troops who got concussions in combat because they didn't consider these "real" injuries. As a result of our story, the Army did its own investigation and put out new guidelines on Purple Hearts. Last week, the Army told NPR that under the new rules, they've finally awarded the medal to almost 1,000 soldiers, including Michelle Dyarman, whom we profiled in our original 2010 reports.

When writer David Foster Wallace committed suicide in 2008 at the age of 46, U.S. literature lost one of its most influential living writers.

The definitive account of Wallace's life and what led to his suicide was published in the New Yorker in March of the following year.

Rev. Sun Myung Moon died Sunday at age 92. The controversial founder of the Unification Church was known for attracting young converts in the 1970s and for conducting mass weddings.

Sun Myung Moon was born in 1920 to a poor family in what is now North Korea. His life took a dramatic turn on Easter Sunday, 1936, when, he says, Jesus appeared before him. As he told cartoonist and interviewer Al Capp, Moon recognized Jesus from a vision he had had at age 3. Moon said he spoke with Jesus in Korean.

"We carried conversation with mind-to-mind, heart-to-heart," Moon said.

As President Obama reintroduces himself to America at the Democratic National Convention in Charlotte, N.C., next week, the Occupy movement will be there trying to do the same.

Remember Occupy Wall Street, originator of the "We are the 99 percent" slogan?

The group, which helped reshape the nation's political discourse last year before falling into disarray and uncertainty, plans to hold a demonstration outside the convention hall in an effort to recapture the spotlight. A Tampa, Fla., Occupy group protested at the Republican convention in there last week.

Two hundred years ago this week, Napoleon Bonaparte fought a battle in Russia that may have begun his undoing. He led his Grand Army against the Imperial Russian Army near a village called Borodino, about 70 miles from Moscow.

It was the single bloodiest day of the Napoleonic Wars, and it's remembered by Russians as a symbol of national courage. An army of re-enactors relived that Sunday.
