Federal investigators on Friday will begin sifting through the wreckage of a business jet that crashed in North Carolina and killed all seven people aboard, including retired NASCAR driver Greg Biffle and his family.

Former racecar driver Greg Biffle and members of his family were among seven people who died in a plane crash Thursday in North Carolina, state police said.

Greg Biffle is famous for racing a car, but he'll be remembered most for how he helped those in need after Hurricane Helene.
