In October 2012, Marvin again obtained an indictment from a [[grand jury]] of Anthony Scott Tubbs for aggravated incest. A six-member trial jury returned a "not guilty" verdict in less than two hours of deliberation. Conspiracy theories claim that several persons in the DA's office manufactured evidence to obtain a conviction against Tubbs. The case caught the attention of the television psychologist Phil McGuire, or "Dr. Phil." The Lifetime Movie Network began filming the production called ''Judicial Misconduct'' in late 2016 in the Shreveport/Bossier City area.
