Tonia Cain

Tonia Cain surrendered Tuesday to the Avoyelles Parish Sheriff's Office, Avoyelles Parish District Attorney Charles Riddle III said.

Cain, the wife of former prison warden Nate Cain, was indicted in January on charges of theft of $25,000 or more, malfeasance and injuring public records, according to Riddle.

Cain's attorney, Jill Craft, said in a written statement that Riddle's office prepared an arrest warrant following the grand jury's indictment and that her client has cooperated throughout the process.

"Tonia voluntarily turned herself in and has continued to cooperate fully in this process," Craft wrote. "While we respect the process, we also look forward to presenting the facts and justice."

Cain previously served as business manager at Avoyelles Correctional Center, but resigned in May 2016 during investigations into her and her husband's actions at the prison.

The indictment followed a legislative audit that suggested she had records shredded in order to cover up that more than $30,000 in cash was missing.

That money came from concession sales at the prison that was meant to benefit clubs that help to rehabilitate inmates.
