In the winter of 1950, Carl Mosser, a 33-year-old man, his wife Thelma, and their three young children left their home in Illinois for a trip to visit relatives in New Mexico. Their journey took an unimaginably tragic turn when they were abducted by a man named Billy Cook. Cook, a recently released convict from Joplin, Missouri, forced his way into the family's car and directed them on a terrifying, meandering drive that led back to his hometown.

The ordeal culminated in the early hours of January 2, 1951, on a street in Joplin. According to Cook's later confession, the family began to scream when a police car passed by, which prompted him to open fire. After brutally murdering the entire family, Cook drove their car for about an hour before disposing of their bodies in an abandoned mine shaft. He then fled, abandoning the family's vehicle in Tulsa, Oklahoma.

The discovery of the Mossers' blood-stained car on January 3, 1951, launched a massive search for the missing family. The tragic end to the search came on January 15, when their bodies were found in the mine shaft on the west side of Joplin. On the very same day, their killer, Billy Cook, was captured in Mexico.

Extradited back to the United States, Cook quickly confessed to the murders of the Mosser family, as well as the killing of another man in California. He pleaded guilty to the Mosser kidnappings and murders and was sentenced to 300 years in federal prison. Following this, he was tried in California for the other murder, found guilty, and sentenced to death. Billy Cook was executed in the gas chamber at San Quentin on December 12, 1952.
