29-year-old Christine Chubbok didn’t leave behind a note. Instead, she staged a grand and memorable performance. Looking healthy, well-groomed, and in good spirits the morning of July 15, 1974, the newswoman geared up for a special presentation. “She was in a much better than normal mood. To this day, her enthusiasm puzzles me,” news director Gordan Galbraith said of her demeanor that morning.
