IN BRIEF: A second suspect and armed robber in the Conyers GameStop shooting-turned-murder pleaded guilty this morning in Rockdale County Superior Court. Tron Hill was sentenced by Judge David Irwin to life in prison plus five years, as recommended by the District Attorney Richard Read's office. Hill's plea comes days after shooter Markus Seymore entered a guilty plea, minutes before Seymore's trial was to begin, and was sentenced to life without parole. Victim Adrian Snow was shot twice when he walked in on the November 2010 armed robbery and died from his wounds in the hospital.
