A widow of one of the twenty-nine people killed in the West Virginia mining disaster earlier this month has filed a wrongful death suit against the mine’s owner, Massey Energy. The suit from Marlene Griffith accuses Massey of aggravated conduct in its handling of working conditions and safety violations at the mine. The Upper Big Branch explosion was the worst mining disaster in forty years. Massey Energy has been cited for thousands of safety violations in recent years, with fifty-seven citations just last month.
