20/20 ABC Tonight: “Dirty Little Secret” March 28 2025

This Friday, March 28, 2025, from 9:01 to 11:00 PM EDT, 20/20 presents a riveting two-hour special titled “Unholy Matrimony”, exploring the shocking and tragic murder of Robert Limon and the sinister plot that unraveled his seemingly perfect life.

Robert and Sabrina Limon seemed to live a dream life with their two children in Silver Lakes, California. They were known for being social and outgoing, often partying with their tight-knit group of friends, known as “The Wolfpack.” However, the facade of their idyllic life shattered when Robert was found murdered in a remote industrial complex where he had been working. As authorities began investigating, they discovered a web of secrets—including the Limons’ open marriage and Sabrina’s affair with a younger lover, firefighter Jonathan Hearn.

While both Sabrina and Jonathan were arrested for Robert’s murder, Sabrina initially walked free due to a lack of evidence against her. But in a shocking turn of events, Jonathan agreed to testify against Sabrina in exchange for a lesser sentence just days before the trial. The episode takes viewers through the complex investigation and courtroom drama that followed, with a focus on the toxic relationship between two former lovers.

This 20/20 special features an interview with Valerie Wass, Sabrina Limon’s appellate attorney, who is fighting to overturn her conviction. The episode also includes interviews with key figures involved in the case, such as Sabrina’s sister, Robert’s family, former friends, and law enforcement officials, providing a comprehensive look at the events leading up to Robert’s death and the legal battle that followed.
