Cold Case Filles: Did claims of teenage pregnancy lead to the murder of a 16-year-old in 1998?

Every June 6, the Family Fellowship Church in Berryhill hosts a solemn vigil in memory of 16-year-old Dena Ann Dean, whose life was tragically cut short in 1998. The tradition began in the parking lot of Marvin’s Grocery at Town West Shopping Center, where Dena was last seen, and later moved to the Berryhill church as the community’s commitment to justice deepened.

On the evening of June 6, 1998, Dena left work at Marvin’s Grocery to meet her boyfriend. She never returned home. Her car was later found abandoned in the parking lot, her purse still inside.

Six days later, her decomposed body was discovered in a field near 51st Street South and 49th West Avenue, close to a pond and not far from the store.

The medical examiner ruled her death a homicide, though the exact cause could not be determined due to the condition of her remains.

In the days leading up to her disappearance, Dena had confided in her boyfriend that she was pregnant. Although the autopsy later confirmed she was not, investigators believe the claim may have played a role in the events that led to her death.

Witnesses reported seeing Dena in a heated exchange with her boyfriend’s father at Marvin’s that night. The father, allegedly upset that his son might abandon college plans due to the relationship, was said to have confronted her aggressively.

Other witnesses described suspicious behavior and interactions at the scene, including the boyfriend’s father appearing at a woman’s house later that night covered in mud, asking to have his clothes washed.

For years, suspicion hovered over the boyfriend and his family. In 2016, new leads pointed toward the boyfriend’s uncle. DNA samples were collected, but the results have never been publicly disclosed. One informant claimed the uncle had threatened the boyfriend’s father to keep quiet about the case.

Despite multiple search warrants and renewed efforts by Tulsa County’s Cold Case Task Force, no arrests have been made. Investigators continue to believe the case is solvable and urge anyone with information to come forward. Tips can be submitted to the Cold Case Taskforce Tip Line at 918-894-94014.

Dena’s mother, Diana Dean, remains hopeful. “If God wants me to know what happened to Dena, then He’s going to help me find that justice,” she said.
