LUCASVILLE, Ohio AP – Another successful execution using a lethal injection of just one drug instead of the traditional three has fueled debate over whether the state’s unique approach should be adopted elsewhere.

In Ohio’s second such execution, killer Vernon Smith was pronounced dead Thursday morning eight minutes after the dose of sodium thiopental, a common anesthetic, began flowing through his body at the Southern Ohio Correctional Facility. In the first such execution, performed last month, it took 10 minutes for Kenneth Biros to die for killing a woman he met at a bar.
