A nearly 40-year-old cold case took a major step toward resolution when Joel Lake Bremer was booked into a Missouri jail and charged with the murder of his pregnant wife. The arrest follows decades of dead ends, an anonymous skull, and a DNA breakthrough.
In 1988, Ronna Bremer, 22, vanished from her home. Her husband reported her missing. He later obtained a divorce, according to KY3. The case went cold as investigators struggled to find answers.
In 1991, investigators received a human skull through the mail. It was not identified as Ronna until DNA testing more than a decade later. She was officially declared dead in 1997.
The case remained unsolved for years before investigators reopened it in late 2024. Sheriff Brad Cole of the Christian County Sheriff's Office said advances in forensic DNA testing allowed detectives to develop a DNA profile from evidence. Investigators say that profile linked Bremer to the crime.
"Technology is great, but you still have to rely on the people that work these cases to be able to put that technology to work and implement it to ask the right questions during these interviews and make sure we get the information we need to get to a point of getting someone charged," Cole told KY3.
This case happened in Missouri, but the reporting came through BakersfieldNow, a California-based news outlet. The forensic DNA techniques used here are the same tools that California law enforcement agencies rely on to revisit unsolved homicides.
Ronna was seven months pregnant when she disappeared. The case remained unsolved for years despite the mailed skull and the 1997 declaration of death. The arrest marks the first major charge in a case that had gone cold for nearly four decades.
Bremer remains in custody on a $200,000 bond. The charge is second-degree murder. The case shows how persistence and forensic science can push old investigations toward justice.
