In the quiet suburbs of Smyrna, Georgia, a shocking discovery was made on October 2, 2005. Kasi Alane Peek, a 44-year-old female computer programmer, was found deceased in her bed, the victim of a fatal gunshot wound. The scene initially appeared to be a burglary gone wrong, with dresser drawers pulled out in an attempt to stage a break-in. However, investigators quickly determined that no valuables were missing, leading them to believe the motive was far more personal and the scene had been manipulated to mislead them. The nature of the crime suggested a deep-seated rage, an 'overkill' in the eyes of law enforcement, pointing the investigation towards those closest to Kasi.
Suspicion soon fell upon her estranged husband, John Peek. It was John who had placed the 911 call, claiming to have discovered his wife's body. As detectives delved into their relationship, they learned the couple had been separated following Kasi's discovery of his infidelity. A crucial and chilling revelation came from Kasi's own sister, who informed police that John Peek's first common-law wife, Carol Marlin, had also been murdered back in 1996, alongside her friend Margaret Ginn. This prior case, a brutal beating death that had remained unsolved for years, cast a dark shadow of suspicion over John. Though he denied any involvement and attempted to point fingers at another woman, his story began to unravel.
The investigation into Kasi's death provided the momentum needed to solve the cold case from nearly a decade earlier. A civil lawsuit filed by Kasi's family uncovered financial motives. Detectives learned that John had been diligently making double payments on Kasi's life insurance policy to prevent it from lapsing during their estrangement. This financial gain, coupled with circumstantial evidence from both murder scenes, allowed prosecutors to build a compelling case. John Peek was arrested and charged with the murders of all three women: Kasi Peek, Carol Marlin, and Margaret Ginn. Facing overwhelming evidence and the possibility of a death sentence, he chose to plead guilty. In April 2007, John Peek was sentenced to three consecutive life sentences, ensuring he would remain imprisoned for his crimes.
