5 Things to Know This Morning

— -- Your look at the five biggest and most buzz-worthy stories of the morning.

1. Theater Attack Suspect Had History of Mental Health Issues

A man with a history of mental health issues was killed by police officers after he attacked patrons inside a movie theater in Tennessee with a hatchet and pepper spray.

Vincente Montano was killed by the Metropolitan Nashville Police Department's SWAT team Wednesday afternoon outside the Carmike Hickory 8 Theater in Antioch, a community southeast of Nashville. Seven other people were watching "Mad Max: Fury Road" when Montano unleashed pepper spray inside the theater and cut one man with the hatchet, said police.

Police said Montano was institutionalized at least three times while living in Murfreesboro, Tennessee, where he was charged with assault and resisting arrest 11 years ago. Police believed he was homeless and had lived in several states over the years, including Missouri, Texas, Alabama, Illinois, and Florida.

2. Aircraft Part Found on Reunion Island From Missing Flight MH370

The plane part that was found on a beach in the Indian Ocean was determined to be part of MH370, the Malaysia Airlines flight that vanished more than a year ago, Malaysia's prime minister said.

The debris is apparently the first piece of physical evidence recovered from the ill-fated plane, which disappeared on March 8, 2014, along with its 239 passengers and crew.

“It is with a very heavy heart that I must tell you, an international team of experts have conclusively confirmed that the aircraft debris found on Reunion is indeed from MH370,” Prime Minister Najib Razak said Wednesday at a brief press conference. "We now have physical evidence that ... Flight MH370 tragically ended in the Southern Indian Ocean."

3. Donald Trump's Debate Game Plan: Wing It

Candidates usually spend hours and hours preparing for a major debate -- reading up the issues, going through practice Q & A sessions or mock debates and practicing lines to use when the big moment comes.

Not Donald Trump.

“Trump doesn’t rehearse,” a senior Trump advisor said Wednesday.

It’s not that his political team hasn’t tried. Trump’s aides have prepared him memos on the issues and the expected lines of questions and potential attacks from the other candidates, but there have been no formal debate prep sessions, no mock Q & A, no practice debates.

4. Netflix and Microsoft: What You Need to Know About Their New Maternity, Paternity Leave

The competition for the best labor talent is heating up as Microsoft and Netflix both make headlines for generous maternity and paternity leave policies that surpass American corporate standards.

Microsoft announced Wednesday it's offering paid parental leave of 12 weeks, "paid at 100 percent, for all mothers and fathers of new children," starting Nov. 1.

This comes after Netflix announced a new policy of “unlimited” maternity and paternity leave on Tuesday.

The video-streaming company, based in Los Gatos, California, introduced an “unlimited” leave policy for new moms and dads to take as much time as they want – with pay -- during the first year after a child's birth or adoption. The new policy applies to all full-time, salaried employees across all countries, the company said. Netflix has roughly 2,000 employees, a spokeswoman said.

5. Wallet Left Behind 70 Years Ago in Austria During World War II Returned to Veteran

A 91-year-old U.S. army veteran now living near Fresno, California, recently got back a wallet he lost 70 years ago in Austria, where he and fellow soldiers helped rescue prisoners from concentration camps, according to his family and the VA Central California Health Care System.

The veteran, Eligio Ramos, completely forgot about the wallet until a fateful letter from an eye doctor in Salzburg, Austria, arrived at his home on June 18, Ramos' daughter Sylvia Gonzalez told ABC News.

"I was having breakfast at home with my dad like our usual routine three days out of the week, and I was reading through the mail when I stumbled upon the letter," Gonzalez, 72, said. "I said, 'Dad! Look! Somebody found your wallet you lost in 1945 in Austria."
