Gone in His Sleep - Bruce Campbell was right next to his wife when he disappeared, although she didn't see it happen. She was asleep. And perhaps so was he. It was April 14, 1959, and Campbell was traveling with his wife from their hometown in Massachusetts to visit their son some distance across the country. It was a long but pleasant drive across the U.S. with plenty of stops along the way. One overnight stop was in Jacksonville, Illinois... and it turned out to be the last stop Mr. Campbell was to ever make. He and his wife checked into a motel and went to bed. In the morning, Mrs. Campbell awoke to find the space next to her in bed empty. Mr. Campbell had vanished, apparently in his pajamas. All of his belongings - his money, car and clothing - remained behind. Bruce Campbell was never seen again and no explanation for his disappearance ever found.
