Supreme Court weighs Davis case

The U.S. Supreme Court could decide whether to hear the case of death-row inmate Troy Davis, who was convicted of killing a police officer almost 20 years ago.

The high court could make its decision as early as Monday on the controversial case involving Davis, who was convicted of the 1989 murder of Savannah police officer Mark MacPhail. His execution has been delayed three times over concerns that he is not the killer.

Supporters say he deserves a new hearing because seven of the trial's witnesses have recanted or backed off parts of their testimony. Prosecutors say the evidence is solid and that the 40-year-old should be put to death.
