A woman who was one of two teenage participants in a killing spree that left 11 people dead 55 years ago and became the basis of the movie "Badlands" starring Sissy Spacek and Martin Sheen has been critically injured in a crash in Michigan.

The Associated Press says 70-year-old Caril Clair of Stryker, Ohio, was critically hurt and her 81-year-old husband Frederick Clair killed late Monday in a single-vehicle crash on Interstate 69 in Calhoun County's Tekonsha Township, 70 miles south-southeast of Grand Rapids.

As a 14-year-old, then-Caril Fugate and her 19-year-old boyfriend Charlie Starkweather went on a killing spree in Nebraska and Wyoming in 1957-58 that claimed the lives of Fugate's mother, stepfather, 2-year-old sister and eight others.

Both Starkweather and Fugate were arrested in Douglas, Wyoming, following the spree, in 1958.  Starkweather was sentenced to death by electric chair, Fugate was sentenced to life in prison.  She was paroled in 1976.
