A grandfather allegedly assaulted by his grandson on Dec. 9 has died of severe traumatic brain injury, and his death now is being investigated as a homicide, according to Fayette County Coroner Gary Ginn.
Taylor Arnett, 78, died at 1:43 p.m. Friday at University of Kentucky Hospital, where he had been in a coma.
Arnett's grandson, Franklin Taylor Arnett, 26, was arrested last month on suspicion of first-degree assault.
Police said Franklin Arnett assaulted his grandfather at his home on 1457 Anniston Drive in Lexington after an argument over taking out the trash.
An autopsy will be performed on Taylor Arnett on Saturday by the state medical examiner's office in Frankfort.
