Lawrenceville police say a long-unknown predator from the summer of 1986 is finally in handcuffs. Investigators have arrested a man they believe carried out a string of apartment rapes that shook parts of Gwinnett County nearly forty years ago, after taking a fresh look at the old evidence and running it through modern DNA testing. For survivors and neighbors who still remember those nights, the development offers long-awaited answers and the prospect of a criminal case returning to court.
According to a Lawrenceville Police Department release reported by FOX 5 Atlanta, investigators identified Glenn Daniel Plybon after resubmitting forensic evidence in 2025 for more advanced DNA analysis. Police say that testing linked Plybon to four rapes over an 11-day span between June 24 and July 5, 1986. In each case, according to the department, a woman was sexually assaulted inside her apartment and the attacker slipped away before officers arrived. Detectives had long believed the incidents were connected based on a similar suspect description and method of entry, but the trail went cold for decades.
How investigators reopened the cold case
Officials credit improved DNA science and coordinated cold case work with finally cracking the investigation. The Criminal Justice Coordinating Council’s Sexual Assault Kit Initiative (SAKI) supplies funding, testing and task force support that state and local agencies say has helped them revisit evidence and pursue long-unsolved sexual assault cases, according to the Criminal Justice Coordinating Council.
Where this fits in a wider trend
Across Georgia, agencies have turned to SAKI resources and private lab partnerships to re-test old sexual assault kits and put names to unknown suspects in cases that had languished for years, underscoring how new testing methods are reshaping cold case work, as reported by The Atlanta Journal-Constitution. Investigators say the Lawrenceville attacks were linked early on but could not be solved until the evidence was reviewed again last year…
