Summary based on the NamUs case record (MP2530) and 6 other sources
In the winter of 1991, a young woman named Sybil Ramona Warren vanished from Greensboro, North Carolina, leaving behind a swirl of unanswered questions. At the time of her disappearance, Sybil was 24 years old. The specific date she was last seen is uncertain, with reports indicating it was sometime in February 1991. She was officially reported as a missing person to the Greensboro Police Department on March 21, 1991. At the time, she was employed as a night clerk at several local motels and was living with her boyfriend. Sybil is described as a Black female with black hair and brown eyes. She has a scar on her right arm from a childhood injury involving broken glass and her two upper front teeth are noted as protruding. The timeline of her disappearance is complicated by the fact that she had reportedly become estranged from her family some years prior, with their last contact being a letter from her dated October 23, 1986.

The circumstances leading up to Sybil being reported missing are somewhat unclear. It was friends who first raised the alarm with the Greensboro Police Department in February 1991. Prior to her disappearance, she maintained a life in Greensboro, working and living with her partner. The disconnect from her family for several years before she was officially considered missing adds a layer of complexity to establishing a precise timeline of events. This estrangement meant that the people who might have noticed her absence sooner were not in regular contact with her. Her case is marked by this vagueness, with the window of when she may have gone missing stretching from as early as October 1986 to February 1991.

Years after she was last seen in Greensboro, a possible sighting brought a glimmer of hope, yet also more questions. In November of 1995, a truck driver who knew Sybil from her time in North Carolina reported seeing her in a shopping mall in Tysons Corner, Virginia. The man, who was friends with her before she disappeared, tried to get her attention, but she reportedly acted as if she did not recognize him. He noted that she appeared to be wearing a work uniform and was in the company of an unidentified man. This man is thought to be Haythan M. Aduroman, who has used several aliases and had been arrested for misdemeanor assault in Virginia in 1982. Despite this lead, Sybil has not been seen since this possible 1995 sighting. The investigation into her whereabouts remains open, as authorities continue to seek answers to ensure her well-being for the sake of her loved ones.
