In the summer of 1984, a young woman named Maria Margarita Colon Seda vanished from Tacoma, Washington, leaving behind a mystery that has endured for decades. On July 1st of that year, the 29-year-old was seen for the last time. At the time of her disappearance, Maria was described as a biracial white and Hispanic female with blonde hair and blue eyes. She stood at five feet, nine inches tall and weighed approximately 150 pounds. Maria was also known to use the name Margaret Seda. The circumstances surrounding her disappearance are not widely known, and there is little public information available regarding what might have led to her going missing. After that day in July, she was never heard from again. The investigation into Maria's disappearance was handled by the Pierce County Sheriff's Office. Despite their efforts, the case yielded few leads, and the trail eventually went cold. The lack of detailed information available to the public makes it difficult to understand the full scope of the investigation. Over the years, her case has been featured on various platforms dedicated to missing persons, including the Charley Project and Uncovered, in the hopes of generating new information that could lead to a breakthrough. These resources serve to keep her memory alive and to remind the public that a family is still waiting for answers. The case of Maria Margarita Colon Seda is a somber reminder of the many individuals who disappear without a trace. With so little information available, the narrative of her life and the events leading up to her disappearance remain incomplete. Her case is one of many unsolved disappearances in Washington state, a collection of stories of loss and unresolved questions. For law enforcement and the loved ones she left behind, the hope remains that someone, somewhere, holds the key to unlocking the truth of what happened to Maria all those years ago. The investigation by the Pierce County Sheriff's Department remains open, a silent testament to a life interrupted and a mystery that continues to plead for a resolution.
