Maria Margarita Colon Seda, also known as Margaret Seda, was last seen in Tacoma, Washington on July 1, 1984. She was 29 at the time, described as biracial white and Hispanic, with blonde hair and blue eyes, standing five feet, nine inches and about 150 pounds.

Details about what happened that day are scarce. The Pierce County Sheriff’s Office handled the investigation, but public information about leads or circumstances is limited and the trail eventually went cold. Her disappearance has been documented on missing-persons platforms including the Charley Project and Uncovered to keep attention on the case.

With so little known about her last movements or contacts, important questions remain about where Maria was heading and who she had been with in the days before July 1, 1984. If anyone knew Maria or has information about her whereabouts around that date, please come forward.
