Karen Silkwood’s death 50 years ago this November continues to haunt Oklahoma and the nation. The 28-year-old plutonium plant worker died in a fatal crash while driving to meet a reporter with The New York Times allegedly to deliver evidence documenting unsafe conditions at the plant. Two reporters who covered the Silkwood story in 1974 have spent years trying to piece together what many in Oklahoma speculate: Karen Silkwood may have died for what she knew. Fifty years later, hear newly-discovered investigative tapes, deathbed conversations and long-awaited interviews reexamining what happened that night.
