With capital punishment on the wane, executions have become the purview of a shrinking number of places.

Democratic nominee Jerri Green called for Commissioner Frank Strada's resignation, while the other three candidates said they wouldn't keep him.

Christa Pike was set to be executed on Wednesday at 10 a.m. CT.

Since 1982, there have been at least 64 botched executions, the vast majority of which involved lethal injection, according to an analysis by the nonprofit Death Penalty Information Center. Seven of those execution attempts failed entirely because officials in Tennessee, Idaho, Alabama and Ohio could not properly insert intravenous lines.

Some past witnesses to executions in Ohio say there have been several examples of botched lethal injections here.
