Jay Lippman was an engineer and chess prodigy who murdered three people over 20 years.
Background
Lippman attended Hudson University in 1983, and distinguished himself by building a computer that could play chess. His intellectual abilities hid a darker side, however; he was a sexual sadist who was aroused by dominating, controlling, and abusing women. In February 1983, Lippman drugged Sally Morrissey, his friend Ricky's younger sister, and raped her with a Coca-Cola bottle. A few months later, Morrissey helped him pick up a young girl named Alyssa Cooney, whom Lippman raped, tortured, and murdered. He then manipulated Morrissey into burying the body in the basement of Morrissey's mother's house. He kept tabs on Morrissey, who had begun abusing drugs to numb his guilt; Lippman knew that someday Morrissey would be either useful or a liability. Later, Lippman married a woman named Anne, with whom he had two children, and became a successful engineer. In 1992, however, his sadistic sexual urges began to resurface, and he raped, tortured, and murdered a prostitute named Lisa Messall. He told Anne that he had been having an affair but had ended it, and kept her in the dark about his sexual inclinations.
Yesterday
When Morrissey's mother died, Lippman persuaded him to move Cooney's body, which had been buried in the basement for nineteen years. When state police found her body, they alerted Capt. James Deakins, who had investigated her murder. He sent Robert Goren and Alexandra Eames to investigate, and they began to suspect Morrissey. Fearing that Morrissey would lead the police to him, Lippman killed Morrissey and made it look like a suicide. Morrissey's death aroused Goren's suspicions, however, and he began to look closer at Lippman. Goren had Lippman arrested and, during the interrogation, made him feel powerless by addressing only his lawyer. Lippman gave in to his need for control and began interacting with Goren, who told him that it took "grand mastery" to suppress his violent urges for so long. Lippman replied "You have no idea" and then burst into tears. He was then arrested and imprisoned for the murders. (CI: "Yesterday")
