A Tennessee man returning early from a trip was allegedly met with an unwelcomed surprise when he arrived home: His 31-year-old wife in bed with a barely-18-year-old man.

Authorities say 41-year-old Jonathan Belk proceeded to stab 18-year-old Billy J. Floyd to death and stuff his body in a trash can. It happened Saturday at a home in the 400 block of Powerline Road in Dunlap, which is about 40 miles north of Chattanooga. When police arrived at the home, they found Belk “standing in his doorway covered in blood,” a criminal complaint obtained by local CBS affiliate WDEF reportedly said.

Cops discovered Floyd’s body in the fetal position stuffed in a trash can, according to cops.

Belk later allegedly admitted to detectives that he attacked Floyd. Belk’s wife also was injured in the attack. She arrived at the hospital suffering from several stab wounds, cops said.

Detectives asked Belk if he was concerned about any major issues other than his legal woes.

“I am worried about my relationship with my wife due to the fact that I offed him,” he allegedly responded.

Belk is now facing several charges including criminal homicide. He remains at the Sequatchie County Jail.

Floyd was from Jasper and went by “Lil Bill,” his obituary said. He just turned 18 three days before his death.

“He enjoyed hunting, fishing, four wheelers and working on everything,” the obituary said. “He mostly enjoyed spending time with his family and friends.”

A family friend started a GoFundMe to raise costs for funeral expenses.
