Katie “Faye” Sinclair was 53 years old when she disappeared from Dewey Beach, Delaware, in July 1993. Online missing-person records describe her as a White/Caucasian woman, about 5 feet 8 inches tall and approximately 130 pounds, with blonde or graying hair and blue eyes. She had pierced ears and a scar on her left forearm from a previous fracture. Some sources also note that she wore reading glasses and had lower dentures.
Katie was last known to be in the area of Cullen Street in Dewey Beach. NamUs lists her last contact as July 10, 1993, at approximately 8:30 p.m. near the 110 block of Cullen Street, while some secondary summaries give July 13, 1993, as the missing date or reported timeframe. The available information consistently places her at a residence or group rental home in Dewey Beach before she vanished. According to the case information, it is believed she left the residence for a short walk, possibly toward the beach, and never returned.
The circumstances are especially concerning because Katie’s personal belongings were reportedly left behind. The only item noted as missing with her was the key to the residence. She was believed to have been wearing a tank top and shorts, with no shoes. She may also have had on a gold ruby and diamond ring on her left ring finger and a gold watch, possibly a Timex, with a brown leather band on her left wrist.
Katie’s case has been classified by public missing-person sources as endangered missing. A key reason for that concern is that she had a medical condition and needed medication. The Charley Project and other public listings echo the same core details: she left for what appeared to be a brief walk, did not return, and has not been heard from since.
A Cape Gazette archive article from 2001 reported that police were still questioning whether Katie Sinclair’s disappearance had been classified correctly. The article described her as having spent about a week at a group rental home on Cullen Street in Dewey Beach before she disappeared, underscoring that investigators had very little clear information about what happened after she left the residence.
The investigating agency listed in NamUs is the Dewey Beach Police Department. The case record names the agency case number as 89-93-001704 and indicates the report date as July 13, 1993. Decades later, Katie’s disappearance remains represented in public missing-person databases with limited known circumstances, leaving a painful absence for those who knew and loved her. Her case is a reminder that behind every brief listing is a person whose life mattered, and a family and community left without answers.Last Seen: Jul 10, 1993
