A Georgia woman is convicted of murdering her husband. Why did she try to incriminate her son?

When the charred remains of prominent commercial real estate attorney Gary Farris were discovered on a burn pile with a bullet lodged in a rib bone, detectives knew they were facing a homicide investigation. The crime scene was on a sprawling 10-acre property in Cherokee County, Georgia, where Gary Farris lived with his wife Melody and their son Scott.

It was July 2018 when detectives found Gary Farris' blood and a second bullet in the basement of the home and questioned how his body could have ended up on the burn pile, about 50 yards away. Soon after their arrival on scene, investigators found themselves entangled in a family drama with mother and son pointing the finger at each other.

"This is a mother's worst nightmare … it has been called the Farris wheel, and it was, but it was our Farris wheel," Melody Farris tells "48 Hours" correspondent Peter Van Sant in an exclusive interview.
