Nov. 11: 'Crossing the Line'

Dateline's Keith Morrison takes a look inside a fatal two-car crash on a Montana highway that left a pregnant mother and her son dead, and a teenage driver clinging to life. Using text messages on a phone found in one of the driver’s cars, investigators would find a minute-by-minute narrative of the events leading up to the collision, leaving some to believe that it might not have been an accident—but murder.

Dateline viewers will hear directly from the teen, Justine Winters, as she tries to explain what might have happened that night, and shares her words for the victims’ family.

Crossing the Line airs Friday, November 11th, at 10pm/9c on Dateline NBC.
