About Robert Spangler
- Robert Spangler (January 10, 1933 – August 5, 2001) was a serial killer who came into the spotlight following the murders of his first wife, son, daughter, and his third wife. On the morning of December 30, 1978, in Littleton, Colorado, Robert Spangler lured his wife, Nancy, into the basement with the promise of a "surprise." and shot her in the head with a .38 Special revolver.
- Going upstairs, he shot his teenage children, Susan and David.
- David was slow in dying, so Spangler finished him off by smothering him with a pillow.
- Spangler then altered the scene to make it appear that his wife had shot their children and then herself.
- On April 11, 1993, when Spangler's third marriage to 58-year-old aerobics instructor Donna Sundling went sour, he took her hiking in the Grand Canyon and pushed her off a 140-foot (40 m) drop to her death.
