A man has been indicted by a Knox County grand jury on two counts of first-degree murder, two counts of abusing a corpse and two counts of felony murder.

Court officials say 28-year-old Joel Michael Guy, Jr. was charged in the killing of his parents, 61-year-old Joel Michael Guy, Sr. and 55-year-old Lisa Guy, at their west Knox County home in November.

Authorities say they believe Joel Guy, Sr. and Lisa Guy were murdered between Friday, November 25, 2016 and Saturday, November 26, 2016. Investigators said both suffered vicious stab wounds, as well as dismemberment. Their remains were found in multiple rooms in the house. Joel Michael Guy, Jr. allegedly placed parts of their remains in an acid based solution in an attempt to destroy evidence. He was arrested on November 29, 2016 in Louisiana. He is being held in the Roger D. Wilson Detention Facility in Knoxville on a two million dollar bond.
