Deborah Ann McKenna, known as Debbie or Coco, was 24 when she vanished from Elizabeth, New Jersey on or about January 14, 1986. She was last seen in the city and never heard from again. Her disappearance remains unresolved and her case was later added to the National Missing and Unidentified Persons System.

Deborah was a white female, 5 feet 2 inches tall, 125–130 pounds, with brown straight collar-length hair and brown eyes. Distinguishing features included scars on her wrists, a previously fractured skull, and a thick leather bracelet bearing her nickname Coco. Friends and family reported she struggled with drug and alcohol abuse and had prior suicide attempts.

Did anyone in Elizabeth around January 1986 remember Debbie, her routines, or where she might have gone?
