NASHVILLE, Tenn. (WKRN/WATE) – Death row inmate Billy Ray Irick selected his “last meal” on Wednesday: a combo of a “super deluxe” burger, onion rings and a Pepsi.

The meal will be provided to Irick on Thursday before his scheduled execution at 7 p.m. He is on death row for raping and killing a seven-year-old Knox County girl more than 30 years ago.

A lot of people wonder about the notorious “last meal” request and how that works for death row inmates. 

It varies state by state. In Tennessee, the “offender can request, within reason, a special meal on the final day before the execution.”  

There’s no clear definition of what constitutes “within reason.”

In the past, these requests have varied widely for Tennessee death row inmates.
