For the fourth time in less than half a year, a member of Burl Cain’s family has resigned from the state prison system under a cloud.

The legendary Louisiana State Penitentiary at Angola warden retired last year after The Advocate asked questions about his business deals with two investors linked to state inmates.

Soon after, his nephew-in-law Kenny Norris retired after The Advocate requested public records that would demonstrate whether he showed up to work at Angola.

Now, Cain’s son and daughter-in-law, Nate and Tonia Cain, have quit as warden and business manager, respectively, of the Avoyelles Correctional Center after the newspaper asked for documents showing prison credit card receipts, inmate concession transactions and records of a prison rape investigation.

Burl Cain was the department’s dominant figure for two decades. The man now in charge of the troubled agency is Jimmy LeBlanc, the ex-warden’s close friend and former business partner. He should have been asking the questions and reviewing the documents that led to the departure of the four Cain family members.

The fact that the department seems unable to investigate its own bigwigs underscores the fact that it needs a new leader who is not tethered to Burl Cain’s web of family ties, personal friendships, professional relationships and business partnerships.
