ATLANTA -- Troy Davis hasn't run out of legal options yet.
The 40-year-old condemned man asked the 11th Circuit Court of Appeals on Wednesday to stay his execution so his lawyers have more time to file a new round of appeals. The filing calls his execution, scheduled for Monday, "constitutionally intolerable."
Davis was sentenced to death for the 1989 murder of 27-year-old Savannah police officer Mark MacPhail.
The Supreme Court last week cleared the way for Davis to be put to death, despite cries from his supporters to reconsider because seven of nine key witnesses against him have recanted their testimony.
But doubts about his guilt and a high-profile publicity campaign have won him the support of prominent advocates including former President Jimmy Carter and South Africa Archbishop Desmond Tutu.
