Margaret “Maggie” Ginn was a kind-hearted, trusted friend and retired Lockheed employee whose life ended in unimaginable violence. In June 1996, she was murdered in her own Marietta, Georgia, home alongside her close friend Carol Marlin. The case would remain unsolved for nearly a decade, leaving her family without answers and her name tied to a painful mystery. Maggie’s murder, later revealed to be part of a broader plot driven by greed and betrayal, became a critical piece of the puzzle that eventually exposed John William Peek’s pattern of deadly deceit.
Maggie’s story was featured in NBC’s Dateline episode Deadly Omission, which revisited the events surrounding her death and how it ultimately led to justice after years of silence.

A Supportive Friend and Respected Colleague
At the time of her murder, Maggie Ginn was 64 years old and enjoying retirement after a career at Lockheed, where she worked alongside Carol Marlin. She was known as a thoughtful, responsible, and loyal person. Friends and family remember her as dependable and generous, someone others could count on without question.
Maggie’s friendship with Carol Marlin extended beyond the workplace. The two often spent time together, shared meals, and remained close even after Maggie left her position at Lockheed. Their bond reflected mutual respect and years of shared experience — a friendship that tragically placed Maggie in the crosshairs of a killer.
A Tragic Night in Marietta
On the evening of June 13, 1996, Maggie hosted Carol for dinner at her home. What began as a routine visit between friends turned deadly. Both women were brutally bludgeoned to death inside the house. The scene showed no signs of forced entry, and nothing appeared to be stolen. The lack of clear motive or suspect left investigators puzzled.
Adding to the strangeness of the scene was a torn Lockheed invoice clutched in Carol’s hand with the name of a fellow employee, Barry Webb, written on it. This misleading clue was later understood to be an attempt to frame someone else and throw off suspicion from the real perpetrator.
Maggie was not the intended target. She was murdered because she had witnessed the crime — collateral damage in a calculated plan to eliminate Carol Marlin and collect on a life insurance policy. Her death was senseless, the result of being in the wrong place at the wrong time, but it was also an act that ultimately helped expose a deeper criminal pattern.
A Decade Without Answers
For nearly ten years, Maggie’s family lived with unanswered questions. The investigation hit dead ends, and despite investigators’ early suspicions about Carol’s husband, John Peek, there was no physical evidence to connect him to the murders. Maggie’s loved ones were left grieving not only the loss but also the lack of accountability.
Her granddaughter, Layla Bryant, later reflected on the pain of knowing the killer remained free. She described the anguish of not having justice, of trying to move forward while still carrying the weight of an unresolved crime. Like the family of Carol Marlin, Maggie’s relatives never stopped hoping that one day the truth would come out.
Justice at Last
The breakthrough in Maggie Ginn’s case came in 2005 with the murder of Kasi Peek, John Peek’s second wife. The similarities between the cases were unmistakable, and when detectives began reinvestigating his past, they connected the dots that had once been dismissed as coincidence.
In 2007, John William Peek pleaded guilty to the murders of Carol Marlin, Maggie Ginn, and Kasi Peek. He received three life sentences without the possibility of parole. For Maggie’s family, it was a long-awaited moment of closure.
Maggie Ginn is remembered not just as a victim, but as a beloved grandmother, a loyal friend, and a woman whose life was stolen far too soon. Her story, like those of the other women involved, serves as a reminder of the hidden dangers that can exist behind a facade — and the enduring strength of those left behind to seek justice.
