Carola Yvonne Davenport, 22, disappeared from Philadelphia after being last seen on October 1, 1975, in the 7200 block of Devon Street with her boyfriend, Robert Wilkins. At the time she was the mother of 11-month-old twins and left behind all her personal belongings, including her clothing and her car, as well as the infants — a departure described as highly out of character. She is Black, with black hair and brown eyes, about 5 feet 4 inches to 5 feet 6 inches tall and 120 to 130 pounds, with a fish-shaped birthmark and burn scars on her left arm and right hand.

No clothing description from the last sighting is available. Her brother filed the missing persons report on February 23, 1976, nearly five months after she was last seen. Both the boyfriend and her son have since died; her daughter and brother have submitted DNA to police databases, but the case remains unsolved.
