Guy faces life terms for the first-degree murder convictions, and must serve at least 51 years in prison before becoming eligible for parole. He also could face additional time for the abuse of a corpse charges, of which he also was convicted. Judge Steve Sword scheduled sentencing on those counts for Nov. 19.
Both victims suffered vicious stab wounds and were dismembered, according to the Knox County Sheriff's Office. The couple's remains were found in multiple rooms in the house. The suspect allegedly "placed portions of the remains in an acid-based solution" in an attempt to destroy evidence. The toxic fluid required specific bio-hazard equipment for removal by a hazardous-materials team.
Guy Jr. was visiting from his home in Baton Rouge, and he and his three sisters spent Thanksgiving with their parents, the sheriff's office said. Guy was arrested three days later at his apartment complex in Baton Rouge.
