Anti-death penalty advocates and community members plan to gather to commemorate the anniversary of the execution in Georgia of Troy Davis.

A coalition of groups is organizing a memorial service Friday evening at First Jerusalem Missionary Baptist Church in Savannah to honor Davis, his sister Martina Correia and their mother Virginia Davis. Virginia Davis died five months before her son and Correia died two months after her brother.

Workshops on Saturday and Sunday in Pooler are set to address what organizers see as problems in the criminal justice system.

Davis was executed Sept. 21, 2011 for the 1989 murder of an off-duty Savannah police officer. His supporters say he was wrongfully convicted and Davis said in his last words that he was innocent of the crime.
