Detailed Case Breakdown
The Mysterious Disappearances of Nancy and Meredith Medina — Unsolved Oklahoma Cold Cases
In the mid-1980s, two Oklahoma women connected through family went missing under circumstances that remain unexplained decades later. Nancy Jean Medina, a 36-year-old mother in the midst of a divorce and custody dispute, vanished from Oklahoma City on August 3, 1984, setting in motion an enduring mystery. Four and a half years later, her step-daughter Meredith Ann Medina, then 16, disappeared from Midwest City on February 14, 1989.
Both cases remain active and unresolved, and while investigators have collected some physical evidence and testimony over the years, no arrests or definitive conclusions have been made.
Nancy Jean Medina — A Mother Who Never Returned
Nancy was last seen on the evening of August 3, 1984, after dropping her two younger children off with a babysitter in Choctaw, Oklahoma. She planned to watch videos with friends, but she never arrived.
In mid-to-late August 1984 — either August 15 or August 22 — her brown 1974 Chevrolet Impala (license plate YP-4876) was found stripped and abandoned roughly 18–20 miles away from where she was last seen, near the old Springlake Amusement Park area in northeast Oklahoma City.
At the time of her disappearance, Nancy was separated and amid a divorce and custody battle with her estranged husband. Investigators have not publicly named him as a suspect, but the divorce context and law enforcement’s belief that foul play was likely involved have kept scrutiny on people close to her.
Meredith Ann Medina — A Teenager Gone on Valentine’s Day
Meredith Ann Medina was born October 29, 1972, and described as a Hispanic female with brown hair and brown eyes. She was last seen at her home in Midwest City, Oklahoma on February 14, 1989, at age 16. Officials classified her disappearance as an endangered runaway, meaning she left of her own accord or under circumstances that couldn’t be clearly categorized.
Meredith has a scar on the left side of her forehead, may wear eyeglasses, and was last known by the nicknames “Mere” or “Ann.”
Her disappearance occurred just a few years after Nancy’s, and while investigators have noted the similarity and family connection, it is still unknown whether the two cases are connected.
Investigative Status — What’s Known Now
– Both disappearances remain open cases with police and cold case units still accepting tips and information.
– Nancy’s Impala was recovered with indications that a struggle may have occurred, though details about what evidence was collected have not been publicly released.
– Meredith’s case remains classified as an endangered runaway by some agencies, though her family and advocates continue to emphasize that she has never been found nor confirmed alive.
– Authorities encourage anyone with information to get in touch with the Oklahoma City Police Department (405-297-1129) for Nancy’s case or the Midwest City Police Department (405-739-1388) for Meredith’s.
– Age-progressed images and missing posters are still circulated through the National Center for Missing and Exploited Children and other national registries.
Despite the years that have passed, both women’s disappearances continue to draw interest from cold case investigators, private volunteers, and the families who hope for answers.

On February 14, 1989, 16-year-old Meredith Ann Medina went missing from Midwest City, Oklahoma.
She was reportedly last seen at her family’s residence. Authorities at the time believed Meredith was a runaway. It’s unclear if her case is still being actively investigated to this day and if any movement has occurred over the years on her Social Security number to prove authorities’ runaway theory.
Strangely enough, her stepmother, Nancy Jean Medina, vanished from Oklahoma City, Oklahoma on August 3, 1984 – four and a half years before Meredith went missing after a messy divorce. It’s not clear if the two cases are connected.
Now 37 years later, Meredith’s case remains unsolved.
Meredith was 16 at the time of her disappearance; if alive today, she would be 53. She is described as a Hispanic female standing 5’3”, weighing 110 lbs, with brown hair & eyes. She has a scar on the left side of her forehead and goes by the nicknames: Mere and Ann. Meredith is listed in NamUs under #MP6388.
