Tommy Zeigler was a successful businessman, a leader in his community, and by all appearances, a dedicated husband and son. All that changed on Christmas Eve, 1975 when tragedy struck at the W. T. Zeigler furniture store. In a special documentary event, A QUESTION OF INNOCENCE examines the balance on the scales of justice, and specifically, the state of the death penalty in the United States through the eyes of Zeigler, who has been sitting on Florida State prison’s death row for almost four decades. Premiering Sunday, November 9 at 8 p.m. ET/9 p.m. PT, the one-hour Investigation Discovery special narrated by Bruce Greenwoodexplores Zeigler’s case and exposes several faults of the judicial process along the way.On July 16, 1976, Zeigler was sentenced to death for four murders he claims he didn’t commit. In light of the already strong evidence, supporters believe Zeigler did not receive a fair trial and the potential for current DNA tests to reveal crucial new evidence has his legal team and supporters hoping for amnesty. On the other side of that scale, Florida Governor Rick Scott started a campaign to clear out death row by accelerating the schedule of upcoming executions. Florida private investigator, Lynn-Marie Carty strongly believes Zeigler has been wrongfully convicted and has uncovered new evidence to support his innocence. Carty is also on the trail of the person she believes is the real killer, but is she too late? The clock is ticking on Zeigler’s life. With no more appeals left and having been on death row longer than any other inmate, the chances are extremely high that Zeigler will face death by lethal injection before the end of 2014.
