Texas housewife Laura Day seemed to have it all: a large home on the water, a loving marriage with her husband David Syring, and a close relationship with her 6-year-old stepson, Taylor Syring. But when Taylor drowned on a beach trip with Day under suspicious circumstances, police discovered her shocking criminal past, and the façade of her picture-perfect life quickly came crashing down. A new “20/20,” in collaboration with Plum Pictures, features ABC News anchor John Quiñones’ exclusive interview with Day from prison, nearly a decade after her first-degree capital murder conviction for Taylor’s death. In the interview, Day opens up about what she claims really happened that day and her past crimes of bigamy and murder while also maintaining her innocence in Taylor’s death, alleging it was an accident. The program includes exclusive interviews with David; Kelly Syring, Taylor’s mother; and Britney Jensen, the prosecutor in Day’s trial. Additionally, the episode contains police footage of detectives interviewing Day, David, and key witness Rene Ruiz, who testified that he saw Day smiling as she drove her unconscious stepson away from the beach. It also reports on how authorities believe Day killed Taylor in order to keep David to herself.
