Death of Karen Silkwood

Karen Gay Silkwood (1946–1974) died in a single-car accident on November 13, 1974, while driving to meet with New York Times reporter David Burnham and union officials. Silkwood, a metallography laboratory technician at the Kerr-McGee Cimarron Fuel Fabrication Site in Oklahoma, had been documenting safety violations and worker contamination at the plutonium processing facility.

In the weeks before her death, Silkwood had discovered evidence of faulty fuel rods being shipped to nuclear power plants and had documented her own plutonium contamination, which she attributed to deliberate exposure by plant management. She gathered documents and photographs to substantiate her allegations and planned to provide this evidence to federal investigators and journalists.

The accident occurred on State Highway 74 near Crescent, Oklahoma. Silkwood's car veered off the road and struck a culvert. Oklahoma State Police concluded she had fallen asleep at the wheel, but investigators found traces of methaqualone (Quaalude) in her blood, though not at levels typically associated with impairment. The documents she was allegedly carrying were never found.

Controversy arose from several factors: Silkwood had told friends she feared for her safety, her car showed possible signs of rear-end impact before the crash, and the missing documents raised questions about whether she had been followed or forced off the road. The Silkwood estate won a landmark $10.5 million judgment against Kerr-McGee for negligent contamination, though the company maintained no wrongdoing in her death.
