Labelled a hate crime by law enforcement, the shooting at the historic black church killed six women and three men were killed, who were all black. One of them is South Carolina state senator Reverend Clementa Pinckney, who was also a pastor at the church, Huffington Post reported.

Dylann Roof, a 21-year-old white male, of Lexington, South Carolina, admitted to shooting the people he had sat with for Bible study at the historic black church, saying he wanted to start a race of war, according to law enforcement officials.  

The church area was off limits to church members and remained a crime scene until Charleston police released it on June 20, Saturday. On June 21, Sunday, people filled the seats of the historic black church for services again and sang hymns as they remembered the nine church members killed by Roof.

Prior to the Sunday service, the Emanuel AME presiding elder Rev. Norvel Goff told CNN he will give the sermon.
