What is the story of Natalie Hemby's verse in "Highwomen"?

Post date: 2019-10-29 15:20:08

Verse 4 of "Highwomen" (by The Highwomen) is sung by Natalie Hemby. I understand the references in the other verses, but I am not sure what incident or historical person(s) this verse is about.

These are the lyrics:
I was a preacher
My heart broke for all the world
But teaching was unrighteous for a girl
In the summer, I was baptized in the mighty Colorado
In the winter, I heard the hounds and I knew I had been found
And in my Savior's name, I laid my weapons down
But I am still around

Knowledge and speculation both welcome.
