The parents of a 28-year-old man planned to cut their son off financially, but he allegedly cut them up before they could.

Joel Michael Guy Jr. was arrested Wednesday for killing his parents, Joel and Lisa Guy, after Thanksgiving in Knoxville, Tennessee.

Both parents were found dismembered on Monday, with body parts scattered throughout the house, according to WBIR. Their remains were discovered after Lisa’s concerned co-workers visited to check on her.

It is believed that Guy Jr. stayed in his parents’ home for some time after they were brutally murdered. He eventually returned to Baton Rouge, Louisiana, where he lives. He was taken into custody Wednesday morning at his apartment.

Guy told authorities he visited his parents on Thanksgiving because he needed money. His parents reportedly had other plans, and were going to tell him they wanted to cut him off, WATE reported.

Joel and Lisa Guy suffered multiple stab wounds and their remains appeared to have been placed in an acid-based solution. Police said the scene was “very gruesome.”

“It would be described as horrific,” Michael MacLean, a police officer with the Knox County Sheriff’s Office, told WBRZ.
