Ashworth was executed by lethal injection at the Southern Ohio Correctional Facility after spending 8 years, three months, and 11 days on death row.
They later went to another bar, and while returning to the Wagon Wheel at around 9 p.m., Ashworth led Baker into an alley where he brutally assaulted him with his fists, feet, and a 6-foot board.
A deputy-coroner later testified that Baker's injuries were consistent with those caused by a high-speed traffic accident or plane crash.
Ashworth became the fourth Ohio prisoner to voluntarily drop his appeals since capital punishment was reinstated in the state in 1999.
For his last meal, Ashworth ordered two cheeseburgers with lettuce and mayonnaise, French fries with ketchup, and drank one Dr Pepper and one Mountain Dew.
