Gregory Michael Peyton has been identified as the lead suspect in the June 3, 1981 murders of 44-year-old Thomas Green and 53-year-old Alice Green in Livermore, California. The case has been cleared by exception due to the death of Peyton.
The Greens were murdered in the bedroom of their home in a violent home invasion robbery. Thomas had been bound with twine and killed by a single gunshot. Alice had been stabbed multiple times and subject to blunt force trauma.
The FGG investigation was conducted by Barbara Rae-Venter of Gene By Gene, the parent company of FTDNA. The confirmation was made through Peyton’s biological daughter who provided a sample of her DNA.
Three years after these killings, in October of 1984, Payton killed his wife and committed suicide in Oklahoma, bringing his tally of murders to three. Peyton was the brother of the Greens’ son-in law.
