Wisconsin elderly couple's perplexing death may never be explained

SUPERIOR, Wis.—When a meter reader discovered the bodies of Richard Ellison and Shirley Johnson four days before Christmas, they were frozen, probably dead for more than 48 hours on the deck outside their house in Superior.

Police a few days later said the couple died from exposure in subzero temperatures, that the deaths were nothing "more than two people locked out of their residence and being exposed to the cold for a prolonged period of time."
