Rebecca Zahau, born March 15, 1979, in Burma (now Myanmar), had come to the United States as a young woman and settled in Arizona, where she worked as a medical professional and began a relationship with Jonah Shacknai, a pharmaceutical executive and founder of Medicis Pharmaceutical. In late June 2011, she was staying at the Spreckels Mansion with Shacknai's six-year-old son, Max, when Max fell down a staircase and suffered catastrophic head injuries. He was hospitalized in critical condition. Two days later, on July 13, Jonah Shacknai's brother Adam arrived at the mansion. The following morning, Rebecca Zahau was found dead. Max Shacknai died in the hospital five days after Rebecca, on July 28. Two people died in the same house within days of each other. The circumstances of both deaths have been questioned.

The message on the bedroom door — painted in black paint, in capital letters, on a wooden door — became the central interpretive puzzle of the case. 'She saved him can you save her.' The sheriff's investigators concluded it was written by Zahau herself before her death, that the bound hands and feet were consistent with self-binding, and that the death was a suicide driven by guilt over Max Shacknai's injury. Critics of this conclusion — including forensic experts hired by Zahau's family — disputed whether a person could bind their own hands behind their back in the manner described, and questioned other elements of the physical evidence. The message itself, with its internal logic and its third-person construction ('she,' 'her'), seemed to some investigators consistent with a self-written statement. To others, it did not.

The San Diego County Sheriff's Office closed its investigation in 2011 with a suicide ruling. No criminal charges were filed. In 2018, Zahau's family brought a civil wrongful-death lawsuit against Adam Shacknai, Jonah Shacknai's brother, who had been the last known person in contact with the mansion before the discovery of the body. Civil cases require a lower standard of proof than criminal proceedings — a preponderance of the evidence rather than proof beyond reasonable doubt. In May 2018, a civil jury found Adam Shacknai liable for the sexual assault and battery, and wrongful death of Rebecca Zahau, and awarded her family $5.2 million in damages. Adam Shacknai denied all wrongdoing. The case was subsequently settled for $600,000, the extent of the applicable insurance coverage.

The Spreckels Mansion — more formally known as Spreckels/Matheson House, a California Historical Landmark — became famous in the worst possible way during the summer of 2011. Coronado, a barrier island connected to San Diego by the sweeping arc of the Coronado Bridge, is known for its naval bases and the Hotel del Coronado, for quiet residential streets and ocean views. It is not a place accustomed to this kind of attention. Rebecca Zahau was thirty-two years old when she died. She had immigrated from Burma, built a career in the United States, and by all accounts was a person of intelligence and warmth. The questions around her death — the bound hands, the painted message, the competing forensic interpretations, the civil jury's finding — have not resolved into a settled narrative. The sheriff's ruling stands. The jury's verdict stands. Both cannot be fully true.
