Federal prosecutors want the trial of Joey Meek, the friend of the man charged in the Charleston church shootings, to be held in the city where the shootings occurred.

Authorities say 21-year-old Meek failed to tell investigators all he knew about Dylann Roof's plans to shoot nine parishioners at the church last June.

In a motion filed Thursday, Assistant U.S. Attorney Jay Richardson asked that Meek's trial be moved from Columbia to Charleston, 120 miles away.

Richardson says that would make it easier for friends and relatives of the shooting victims to attend, and he noted that a number of witnesses are from the Charleston area.

Richardson says the convenience of the defendant does not outweigh the convenience of the victims. Meek is from the Columbia area.
