Lawrence Grady was a scientist at the Summerholt Neurological Institute and the father of Kevin and Dillon. While out hunting with his sons, Lawrence shot and killed Dillon. To cover for himself, Lawrence subjected Kevin (a witness) to an experimental memory treatment at Summerholt, to make him forget about what he had seen and managed to convince Kevin that it had been he who shot Dillon.

Lawrence's plan began to crumble, when Kevin escaped Summerholt and attracted the attention of Clark Kent, Lois Lane and Chloe Sullivan. After Sullivan broke into Summerholt and acquired evidence of his guilt, Lawrence attempted to erase her memories. However, he was stopped by Clark and Kevin, who had managed to recover his true memories. Afterwards, Lawrence was taken into custody.
