SAVANNAH, Ga. -- The older sister of Troy Davis, who fought for years to clear her brother's name before he was executed on Georgia's death row, has died two months after attending her brother's funeral in Savannah.
Martina Davis Correia died Thursday at age 44 after a long battle with cancer. Correia's younger sister, Kimberly Davis, confirmed her death to The Associated Press.
Troy Davis was executed Sept. 21 for the 1989 slaying of off-duty police officer Mark MacPhail -- a crime Davis insisted he didn't commit. Correia worked for years with Amnesty International and other groups to challenge her brother's conviction.
Correia was hospitalized shortly before her brother's execution, but joined demonstrators outside the prison the night he was put to death. She vowed afterward to keep fighting capital punishment.
