How Arizona, Ohio, Oklahoma, executions went awry Since the start of the year, executions in Ohio, Oklahoma and Arizona have gone awry, with inmates gasping for breath as lethal drugs coursed through their bodies. Joseph Rudolph Wood was convicted of fatally shooting Debbie Dietz, 29, and her father, Gene Dietz, 55, at their auto repair shop in Tucson in 1989. Clayton Lockett was convicted of shooting Stephanie Nieman, 19, with a sawed-off shotgun and watching as two accomplices buried her alive in 1999. Wood looked around the death chamber and glanced at the doctors as they made preparations for his execution Wednesday in Florence, Arizona. [...] while the procedure typically calls for one IV to be inserted into each arm, the medical team had difficulty finding a suitable vein and instead opted for a single IV into Lockett's groin that was covered with a sheet. Wood looked at the family members as he delivered his final words, saying he was thankful for Jesus Christ as his savior. FIRST TROUBLE: What was particularly unusual was the five minutes or so that McGuire lay motionless on the gurney after the drugs began flowing, followed by a sudden snort and then more than 10 minutes of irregular breathing and gasping. After learning there was a problem with the IV and that some of the drugs had leaked into Lockett's tissue or out of his body, the state's prison director called a stop to the execution. The results of a state autopsy are pending, and an official cause of death has not been released. Oklahoma Gov.
