An execution at this Ohio state prison appears to go horribly wrong.<br/> <br />The execution was done with a new two-drug lethal injection method, which was used for the first time in the United States.<br/> <br />Witnesses say this man, Dennis McGuire, convicted of rape and murder, convulsed and appeared to struggle for breath during his execution.<br/> <br />(SOUNDBITE) (English) UNIDENTIFIED WITNESS TO EXECUTION SAYING:<br/> <br />"I would say for 10-13 minutes Mr. McGuire appeared to be gasping for air. I don't know if it was air hunger or exactly what it was but all I am going to tell you is that the description - he gasped deeply, there was kind of a rattling, guttural sound, there was kind of a snorting through his nose. Couple of times he definitely appeared to be choking."<br/> <br />McGuire received a combination of the sedative midazolam and the pain killer hydromorphone, a mix Ohio created as a substitute option.<br/> <br />The producer for Ohio's preferred drug had objected to its use in executions.
