Troy Davis is trending after the Georgia Pardons Board denied his 11th-hour plea for clemency.
Davis has served 20 years on death row in Georgia since being convicted of murdering a police officer in 1989 in Savannah. Davis, who has always maintained his innocence, has supporters around the world, including Pope Benedict and Desmond Tutu. Hundreds of vigils have been held in the last week.
Davis’ lawyers point to a lack of DNA evidence linking him to the murder and a number of key eye-witness recantations after his conviction.
Former President Jimmy Carter says, "This case illustrates the deep flaws in the application of the death penalty in this country.”
Davis will die via lethal injection at 7 p.m. Eastern on Sept, 21, barring intervention by the U.S. Supreme Court, which is considered unlikely.
