Troy Davis case
Since Davis' trial, seven of nine key prosecution witnesses who testified against him have recanted their testimony. Here, Tonya Johnson, expresses regret during a July 2007 interview for not having told the whole truth during Davis' murder trial. Johnson has come forward with new testimony implicating a different suspect. She said she was afraid for her safety, fearing the other suspect would harm her. Curtis Compton / ccompton@ajc.com
