Gabriel Thomas is a pharmaceutical representative who was the prime suspect in a series of rapes that were actually committed by his twin brother Brian Smith.
He was charged with multiple rapes and sent to prison. After hurting himself in prison, Gabriel's wife said that she told detectives that she couldn't believe it and that he was the sweetest man in the world, stating that when she miscarried several years ago, he didn't leave her side for the whole weekend. She then added that his parents were dead within months of each other, and that she and their six year old son were all that he had in the world.
He told the detectives that he is adopted, and his parents were good people so never made contact with his birth mother. When Benson and Amaro find her, she tells them about giving up identical twin boys 36 years before. She went onto say that one of the boys, Brian, found her and wanted to reconnect. She told them about having a twin, and shortly after their visit he was forced to testify against his adoptive mother because he watched as she drugged her husband and set him on fire.
