The GBI released sketches Wednesday of two men wanted for questioning in the fatal shooting of a Union City couple.

Shannon Deshun Bell Sr. and Conswellow Bell were shot to death and their two sons, 12 and 19, were wounded in the family's Tartan Court home on March 31.

Police have said that "ongoing illicit activity" inside the Shannon Glenn subdivision house precipitated the shootings, and the family was targeted.

Anyone with information on the identities of the men in the sketches or their whereabouts should call Detective Sgt. Cliff McClure at 770-515-7831 or Union City police at 770-964-1333.
