The longest-serving warden in Angola history has decided to give up his post at the end of the year.

Louisiana Radio Network reports Angola Warden Burl Cain's resignation comes weeks after The Advocate newspaper published articles questioning whether his real estate deals with relatives and friends of inmates violated the Department of Corrections rules.

Cain, who's 73 years old, told LRN when the paper questioned his religious beliefs, he knew it was time to go.

"I guess the religious belief was the snowflake that pushed me over the edge," he said.

As for his accomplishments as warden, he said his biggest one doesn't lie with the buildings on the prison campus.

"But what's in the hearts of the men here, because that will really never go away," he said. "That's the greatest change. The moral rehabilitation we have, that's what counts."

Corrections Secretary Jimmy Leblanc will appoint Cain's successor. It's believed he'll select Dixon Correctional Institute Warden Darrell Vannoy to replace Cain at Angola.
