In 1990 Tim and Elaine Boczkowski were living in Greensboro, North Carolina with their three children, 9 year old Randy, 6 year old Sandy and 5 year old Todd. Tim was an entrepreneur, and Elaine was a stay-at-home mom. Elaine was a devout Catholic and fantastic mother by all accounts. But in 1990, Boczkowski's lives changed forever when Elaine died in a tragic accident. But that "accident" was thrown into question when Tim married Maryann Fullerton in 1993, only for Maryann to die in a very similar accident 18 months later.
