Ensign Andrew L. Munn's was a soldier in the U.S. Navy in Vietnam.

Now he's buried in Arlington National Cemetery.

He died in 1968 while serving aboard the USS Kakapon in the Philippines. But his death didn't come by way of enemy fire. His death was a mystery.

Some suspected foul play. Some called it an accident.

The Navy's official stance was that Ensign Munn's went AWOL, that he was a deserter and a disgrace.

For Andrew's sister, Mary Lou Taylor, that was an answer she couldn't live with.

She knew deep down in her gut who her brother really was, and what kind of person he was.

She knew he would never desert his post. And that meant he must have been murdered.

From A&E, this is Cold Case Files, the podcast.

I'm Brooke, and this story, adapted from a classic episode of Cold Case Files, is told by the resplendent Bill Curtis. Well, we're going to go up the hill to my brother's gravesite.

It's always hard to find it because there are so many.

Mary Lou Taylor walks past row after row of headstones.

Each marks the resting place of an American hero.

In at least one case, the headstone memorializes a murder victim.

This is it.

In memory of Andrew L. Munn's, Ensign, U.S. Navy, Vietnam, October 12,

1943, January 17, 1968.

Andrew Munn's was Mary Lou's brother.

when he disappeared without a trace.
