Pamela Sue Dalton was 33 when she vanished from St. Louis, Missouri, around May 1, 1991. A mother of two young boys, she is described as a white female with brown hair and brown eyes, a discoloration on her left wrist, a C-section scar, a rose tattoo on her breast and an ankle tattoo reading either Lynn Allen or LAD.

One account says she was riding north from Sikeston, Missouri, on a motorcycle with an unidentified man. A relative reportedly took a distressed call in which Pamela asked for money to be wired and said she wanted to come home; she never called back. The Sikeston Department of Public Safety handles the investigation and the case remains active.

Does anyone have information about Pamela’s last known movements or the man she was traveling with?
