Summary based on the NamUs case record (MP20468) and 3 other sources
In the quiet community of Castle Rock, Washington, a family's life was forever altered on the morning of November 11, 2001. On that day, 49-year-old Rex Richard O'Cain was seen for the last time leaving his home. A man of 49, with brown hair and blue eyes, his sudden departure left a void filled with unanswered questions. Standing between 5 feet 10 inches and 6 feet tall, and weighing around 140 to 150 pounds, Rex was a noticeable figure. His loved ones were left to wonder what had become of him, as he vanished without a trace, leaving behind personal effects that suggested he did not intend to be gone for long. The days that followed his disappearance were filled with a growing sense of unease as there was no communication from him.

The circumstances surrounding Rex's disappearance are unsettlingly sparse. He simply left his residence one morning and was never heard from or seen again. An unnerving detail in his case is that he had no teeth and left his dentures behind, a personal necessity one would almost certainly not leave intentionally if planning a long journey. He also had a distinctive tattoo of an upside-down 'Y' on his right upper arm, on the outside of his bicep. These details paint a portrait of a man who seemingly vanished from his own life, leaving behind crucial personal items and a family to grapple with his unexplained absence. The official report was filed with the Castle Rock Police Department three days after he was last seen, on November 14, 2001, marking the formal beginning of a long and frustrating search for answers.

For years, the investigation into Rex O'Cain's disappearance has remained open, a cold case in Cowlitz County. Despite the passage of time, the hope of discovering what happened to him has not been extinguished. His case was formally entered into the National Missing and Unidentified Persons System on June 4, 2013, ensuring his information is accessible to law enforcement agencies and the public nationwide. The overview of this case is one of profound and sudden mystery. A man in his late forties disappears from his home in a small Washington town, leaving behind essential personal belongings. With no witnesses to his disappearance after he left his residence and no communication since, his family and investigators are left with a collection of troubling facts and a scarcity of leads. The case remains a poignant reminder of the enduring pain and uncertainty that surrounds the lives of the missing.
