Charleston Shooting: Mourners Gather for Prayer Service at Morris Brown AME Church

Supporters gathered on a hot day at Charleston's Morris Brown AME Church.

— -- Mourners gathered on a hot Charleston, South Carolina, day at a church prayer service, honoring the nine people killed when a gunman opened fire at another church Wednesday night.

The inside of Morris Brown AME was packed today, from the ground level to the balcony level. An overflow room was even set up for people to watch on monitors.

"Please break your silence. Please speak up," he said.

The mood alternated between somber and lively, particularly during upbeat hymns.

When the bishop of the church announced that the suspect had been apprehended, there were loud cheers and applause from the crowd.

As the vigil got quieter inside, you could hear a crowd outside singing, "This Little Light of Mine."
