Like many a good little Catholic girl, as a child Shannon Mohr thought she wanted to be a nun when she grew up. A sweet and caring child who was both a daddy’s girl and a mommy’s best friend, she eventually decided that she wanted to marry and have a family. Nursing suited her caring and compassionate nature and it was a natural fit for her.

Shannon left Toledo and moved to Dave’s 100-acre farm in Hillsdale County, Michigan, where he grew corn and soybeans. She was able to find a nursing job at the nearby Flower Hospital in Sylvania. Shannon’s salary was the only real income in the Davis household; it’s unknown what excuse Dave gave her for the lack of cash flow.

On July 23, 1980, only 10 months into the marriage, Shannon and Dave took their Tennessee walking horses to visit their neighbor, Dick Britton. Dave helped Dick repair some machinery and then he and Shannon trotted…
