While definitive answers of what happened on that Logan County road have not been found, other parts of Silkwood's story are now much less mysterious.
It has been 51 years since nuclear whistleblower Karen Silkwood died in a crash on a rural Oklahoma highway while headed to meet a reporter with the New York Times.
She was set to expose evidence that the Kerr-McGee plutonium plant she worked at in Crescent was putting workers in unnecessary danger and taking quality control shortcuts. The documentation she had with her was never found.
Her story inspired the Oscar-nominated film "Silkwood" and led to change within the nuclear industry.
While her story is one of inspiration, it is also one of tragedy. Silkwood was a 28-year-old mother. When she died, her three children were left to grow up without their mom.
Silkwood's son, Michael Meadows, now has adult children of his own. He has spent years searching for answers to what really happened on Nov. 13, 1974.
"There’s no telling if we’ll ever get an absolute answer—definitive closure—but if anybody knows anything or if there were confessions, or if they passed the story onto their children, those are the people that we’re really trying to find. Maybe you weren’t directly involved but you know somebody that was, or you’ve got this document, that document, we just are running out of time," Meadows said.
