Summary based on the NamUs case record (MP5956) and 9 other sources
In the autumn of 1983, a season of change, fifteen-year-old Joyce Irene Cogburn and her sixteen-year-old sister, Josephine, found themselves in a new and unfamiliar environment. On October 2, 1983, the sisters vanished from Norman, Oklahoma, a place they had only recently begun to navigate. The girls were staying in the apartment of a male family friend, who had been granted temporary custody. This man was the one to report them missing, claiming they had intended to go to the library and never came back. All of their personal items, including clothing and photo albums, were left behind in the apartment. Joyce was a young woman with blonde hair, brown eyes, and pierced ears, standing at five feet three inches and weighing around 116 pounds.

The sisters' childhood had been marked by instability and hardship. Their father was tragically killed in a car accident in 1968, a time when their mother was pregnant with Joyce. In the aftermath, the three sisters were separated, with Joyce and Josephine going to live with their paternal grandparents and their older sister, Rosetta, with their maternal grandmother. The family was reunited in 1975 when their mother remarried, but this new chapter brought its own set of challenges, including allegations that the stepfather had tried to molest the younger girls, which led to the end of that marriage. In 1983, following some disciplinary issues at their home in Broken Bow, Joyce and Josephine went to live with the family friend in Norman. It was from this new residence that they disappeared without a trace.

Initially, law enforcement treated the disappearance as a runaway case, a common assumption when teenagers go missing. However, as days turned into weeks and then years with no contact or use of their Social Security numbers, the likelihood of a more sinister explanation grew. Foul play is now suspected in their disappearance. The family friend they were living with has been identified as a person of interest in the case, though he was never officially named a suspect. According to the sisters' older sister, Rosetta, Josephine had confided that Joyce had been in a relationship with this man but had recently started seeing someone new and wanted to end things with him. This has led to speculation that a jealous rage may have been a motive. The man, who has since passed away, reportedly refused to cooperate fully with the investigation, declining a polygraph test and failing to return the girls' belongings to their family. Over the years, there have been several unconfirmed sightings, but none have led to a breakthrough in the case. The disappearance of Joyce and Josephine Cogburn remains an unsolved mystery, a painful and lingering question for their loved ones who still hope for answers.
