Richard was the manager of the Humboldt Bay National Wildlife Refuge in northern California. He had completed training at the Federal Law Enforcement Training Center in Glynco, Georgia, so it's easy for his friends to imagine that he was involved in the heroic efforts of the passengers that day.
"Richard would have been one of the ones to intervene," said Dave Paullin, his supervisor at the U.S. Fish and Wildlife Service.
A stained glass artist, Richard Guadagno hunted, fished, camped, hiked, studied the stars and worked in his greenhouse. He spent most of the last year supervising work on a new visitor's center at the refuge. "He watched over that project like a mother hen," Paullin said. "He really wanted it to be an asset to the community. He was looking forward to showing off 'his' refuge."
