KNOXVILLE – Tennessee investigators say a Baton Rouge man murdered his parents in Knoxville then tried to dissolve their bodies in acid after Thanksgiving.

The Knox County Sheriff's Office charged 28-year-old Joel Michael Guy with two counts of first-degree murder Tuesday.

Deputies say Guy murdered his parents, Joe and Lisa Guy, between Friday night to mid-day Saturday at their home in Knox County, Tennessee. Guy then tried to dissolve their bodies in a homemade acid-based solution before returning back to Baton Rouge on Sunday.

Knox County investigators say both bodies had multiple stab wounds and had been dismembered. According to a WATE report, deputies described the crime scene as "very gruesome" and "horrific." Remains were disposed of in multiple rooms, according to WATE.

Detectives told WATE that there is information that Guy's parents were planning to stop supporting their son financially. The parents planed to tell Guy on Thanksgiving Day.

Neighbors told WBRZ's Brett Buffington that Guy lived alone and kept to himself at his Baton Rouge apartment. Neighbors said they saw Guy on LSU's campus before, but a spokesperson for LSU said that Guy is not currently enrolled at the university.

Guy is currently being held at the East Baton Rouge Parish Prison and is awaiting extradition to Knox County where he will stand trial for the two counts of first-degree murder.
