An example of how appearances can be deceiving.

Richard was homeless in the city of New York.

But he was also a multi-millionaire!

Looking through the photos of Walters` life, you see a military man, a successful aeronautical engineer, a philanthropist.

"He was private, extremely frugal, non-materialistic," remembers friend Rita B.

But Walters also lived a mysterious life.

Rita first met him at a Scottsdale senior center.

She knew Walters for years before discovering he was homeless by choice.

"I had no clue he was a multi-millionaire. That just blew me away."

Walters never married or had children.

After retirement, he decided to let go of material possessions.

"I think he wanted to experience a different type of life," saysRita.

Walters died two years ago at age 76, leaving about $4 million to both a Catholic mission.
