The State of Georgia is preparing to execute Troy Davis tomorrow (September 21).

Davis, currently 42 years old, was convicted in 1989 of the murder of an off-duty Savannah police officer in a local Burger King parking lot.

A murder weapon was never recovered in the case, nor was there any physical evidence that linked Davis to the crime. Also, 7 of 9 witnesses have reneged statements claiming coercion by police.

In July 2009, two of the jurors that sentenced Davis signed affidavits saying that based on the retraction of statements from witnesses, Davis should not be executed.

Over 650,000 signatures have been collected in support of having a new trail for Troy Davis.

Prominent high profile figures including former President Jimmy Carter, Al Sharpton, Pope Benedict XVI, presidential candidate Bob Barr, and Former FBI Director and Judge William S. Sessions have called upon the courts to grant Davis a new trial.
