Tomb Stone

Up at the Kebler pass heading to Crested Butte, is the Irwin Cemetery.

On Mary's tombstone, it reads:

"My good people, as you pass by;

 As you are now - So once was I;

 As I am now, You soon must be;

 Prepare yourselves to follow me"

I understand there was a gun fight over Mary, and she stepped between two  boyfriends and was shot and killed. 
 Age 17.
