NASHVILLE, Tenn. (WKRN) — A convicted killer has died after spending more than two and a half decades on death row.

Officials with the Tennessee Department of Correction say Dellinger died of “apparent natural causes.”

Dellinger was originally sentenced to death in 1996 for first-degree murder in Blount County.

Dellinger’s exact cause of death is pending, as officials await the medical examiner.
