LUCASVILLE, Ohio — Ohio on Thursday put to death a South Korean immigrant store owner's killer with the country's first use of the surgical sedative pentobarbital as a stand-alone execution drug.
Johnnie Baston was pronounced dead at 10:30 a.m., about 13 minutes after the 5 gram dose of the drug began flowing into his arms. About a minute into the execution, Baston appeared to gasp, then grimace and wince, but then was quickly still.
