MURFREESBORO, Tenn. (WKRN) — A Murfreesboro man is dead and his wife is in the hospital after their son allegedly attacked them Wednesday night.

It happened in the 1700 block of Colyn Avenue around 9 p.m. Wednesday.

Police officers were originally called to the home for an “unknown problem,” but once on the scene, they found DeJahn Tyson, 21, standing over his father with an object in his hand.

Following the preliminary investigation, officers determined DeJahn’s father, 54-year-old Perry Tyson, had been stabbed and beaten to death. Although officers attempted to render aid, Perry was pronounced dead at the scene.

DeJahn’s 55-year-old mother was also transported to the hospital with non-life-threatening injuries. She is also being treated for stab wounds and is said to be in stable condition.

Two other people were in the home at the time of the stabbings, but they were not hurt.

DeJahn was arrested at the scene and transported to the Rutherford County Adult Detention Center. He is being held on a $1 million bond.

This investigation is ongoing and police say there is no clear motive at this time.

DeJahn Tyson is due in Rutherford County General Sessions Court on April 28 for a hearing.
