"He was dead," Houston said. "He had no heartbeat and he wasn't breathing. I started CPR, and after a few minutes, he revived and started breathing again. He knew his name and his wife's name."

What happened next astounded Houston and the victim's wife.

"The first question he asked was 'Did I vote?'"

Dumbfounded, the man's wife told him that whether he voted was the least of their concerns.
