CHARLESTON, S.C. -- Hundreds gathered in downtown Charleston, for a "Unity walk" to remember the nine victims who died in the Charleston Church shooting two years ago.

It was one of many gestures to remember the Emanuel Nine.

Nine doves were released, each bird representing one of the nine killed by Dylann Roof, a self-proclaimed white supremacist who was caught in Shelby one day after the shooting, convicted in December and sentenced to death in January 2017.

But Saturday was all about remembering, with architect Michael Arad commissioned to design a memorial.

"If I can show what is already here in a memorial, I know that we will succeed," said the man who's famous for designing the September 11 memorial in New York City.

There is no timetable on the memorial.
