Marian Elizabeth Brown, a White woman from Sussex County, Delaware, disappeared from the Greenwood area on October 11, 1970. She was about 5 feet 4 inches tall and roughly 160 pounds, with brown hair and blue eyes. Records list her age as either 45 or 46 at the time. She was last seen at or near her home while cooking dinner for her two children and was never heard from again.

Reports say her marriage had been troubled and that she and her husband had previously separated but were living together again when she vanished. Some accounts mention an unconfirmed tip that she may have gone to Puerto Rico.

Investigators have treated the case with concern; the Charley Project reports a man who died in 1988 allegedly confessed to her murder to several people but never identified any remains, and it is unclear whether he was responsible. The Delaware State Police are listed as the investigating agency. Does anyone have memories or information about Marian, her whereabouts in October 1970, or the Greenwood area at that time?
