Evidence has recently surfaced that there may have been more conspirators in the Oklahoma City bombing for which Timothy McVey was executed. The only person who would know with certainty is dead. He can never be asked.

There have been numerous cases of multiple muderers, Ted Bundy for example, being executed with questions about how many crimes they actually may have been responsible for still unanswered. Unidentified bodies that turn up years later could possibly be tied to convicted muderers, but nobody's ever going to know for certain if said murderer has been executed.

Execution is final. Any questions that didn't get answered before the sentence is imposed may as well just go unasked.
