WASHINGTON, D.C. -- The United States Supreme Court says it needs more time to look at an appeal from Georgia death row inmate Troy Davis.
The Supreme Court issued a stay of execution for Davis in September, just 2 hours before he was set to die.
Davis was convicted of murdering an off-duty Savannah police officer in 1989.
Davis and his supporters want a new trial because several witnesses have reportedly changed their story.
Prosecutors have labeled the statements of witnesses who recanted "suspect," and courts have refused requests for a new trial.
Davis wants the high court to order a judge to hear from the witnesses who recanted their testimony and others who say another man confessed to the crime.
Influential advocates, including former President Jimmy Carter and South Africa Archbishop Desmond Tutu, insist that there's enough doubt about his guilt to merit a new trial.
A divided Georgia Supreme Court has twice rejected his request for a new trial, and had rejected his appeal to delay his execution.
