More than five decades after an 18-year-old woman vanished in the middle of the night, her death remains one of the most troubling unsolved cases in Cedar Rapids history.
Paula Jean Oberbroeckling had just graduated from Washington High School in 1970 and was beginning to build her future. She worked at Younkers in Lindale Plaza and spent time helping children with disabilities. Those who knew her described her as kind, responsible, and independent.
Disappearance in the Early Morning Hours
According to reports at the time, Oberbroeckling went out on a date the night of July 11, 1970, with her boyfriend, identified as Lonnie Bell. After returning home, the two reportedly argued.
Around 1 a.m., she borrowed her roommate’s car, saying she would be back shortly. She was last seen wearing a light blue dress.
She never returned.
The vehicle was discovered the following day about two miles from her home near a local grocery store. Investigators found no immediate signs of a struggle, leaving few clues about what happened after she parked the car.
Months of Uncertainty
In the weeks that followed, family members and volunteers conducted searches across the area while authorities investigated her disappearance. Despite widespread concern, police initially stated there was no clear evidence that Oberbroeckling had been harmed.
That uncertainty persisted for months.
Body Discovered Near Cedar River
On November 29, 1970, a man and his two sons found human remains in a ravine near the Cedar River, roughly six miles from Oberbroeckling’s home.
The body, later identified through dental records, was confirmed to be Oberbroeckling. She was still wearing the same dress from the night she disappeared.
Authorities noted several troubling details at the scene. Her hands and feet had been bound with rope, and her body had been positioned around a metal stake in the ground. Investigators quickly ruled the death a homicide.
Due to the condition of the remains, however, an exact cause of death could not be determined.
Lingering Questions and Theories
Over the years, investigators and independent researchers have explored multiple theories, but no suspect has ever been charged.
Among the key questions:
- Whether someone Oberbroeckling knew was involved
- Why her car was left where it was found
- What happened in the hours after she left her home
Some reports at the time suggested she believed she might have been pregnant, though that information was never publicly confirmed. Others have pointed to the argument earlier that evening as a possible factor.
The bindings found on her body have also been a focal point, indicating she may have been restrained.
Case Still Open
Despite the passage of time, the case has never been officially solved and remains open as a cold case.
Renewed interest in recent years, including reporting and research by journalist Katherine Dykstra, has brought new attention to the investigation and raised questions about how it was handled in its early stages.
For Oberbroeckling’s family, the lack of answers has stretched across generations.
Anyone with information about the case is encouraged to contact local law enforcement.
