LAWRENCEVILLE, Ga. — Authorities have announced the arrest of a suspect. This suspect is connected to a series of violent sexual assault cases dating back nearly 40 years. This marks a major breakthrough in a long-unsolved investigation.
The Lawrenceville Police Department and the Georgia Bureau of Investigation (GBI) worked together. They confirmed that 60-year-old Glenn Daniel Plybon has been taken into custody. This is related to several rapes that took place in the City of Lawrenceville. These incidents happened during the summer of 1986 in unincorporated Gwinnett County.
Plybon was arrested at his home in Oglethorpe County. Officials confirmed this followed renewed investigative efforts. There were also advancements in forensic technology. The case remained unsolved for decades. It was recently reopened in 2025. This occurred as part of ongoing efforts to bring justice to victims of cold cases.

Investigators say that during the summer of 1986, multiple adult female victims reported being sexually assaulted inside their apartment residences. In each case, the suspect allegedly fled the scene. This happened before law enforcement arrived. This delay made it difficult for authorities to find and apprehend a suspect at the time.
Law enforcement officials noted that there were similarities across the cases. This included the method of entry and the physical description of the suspect. These similarities suggested a pattern. Investigators believed the incidents were connected. Despite extensive investigative work in the years after the crimes, including interviews and identification procedures, the case remained unsolved.

The breakthrough came after investigators revisited the evidence using modern forensic tools. Advances in DNA technology and investigative genealogy played a key role in identifying Plybon as the suspect, officials said.
“Our detectives’ persistence and dedication show that we never give up fighting for victims of crime,” said Lawrenceville Police Chief Mullin. “This arrest demonstrates how advancements in DNA technology can bring long-awaited justice.”
GBI Director Chris Hosey also emphasized the importance of continued efforts in solving cold cases. He stated that even decades-old investigations can be resolved with new leads. Evolving technology also plays a crucial role in these resolutions.
The authorities report that the investigation is still active. They encourage anyone with extra information related to the case to contact the Lawrenceville Police Department.
Officials reiterated that an arrest does not equate to a conviction. The suspect is presumed innocent until proven guilty in a court of law.
The arrest brings renewed attention to the importance of forensic advancements. It highlights the determination of law enforcement agencies to seek justice for victims, regardless of how much time has passed.
