ATMORE, Ala. — A man who killed an Alabama convenience store clerk more than two decades ago was put to death Thursday night, an execution that required two consciousness tests as the inmate heaved and coughed 13 minutes into the lethal injection.

Ronald Bert Smith Jr., 45, was pronounced dead at 11:05 p.m., about 30 minutes after the procedure began at the state prison in southwest Alabama. Smith was convicted of capital murder in the Nov. 8, 1994, fatal shooting of Huntsville store clerk Casey Wilson. A jury voted 7-5 to recommend a sentence of life imprisonment, but a judge overrode that recommendation and sentenced Smith to death.

Smith heaved and coughed repeatedly, clenching his fists and raising his head at the beginning of the execution. A prison guard performed two consciousness checks before the final two lethal drugs were administered.(nydailynews.com)…[+]
