Wal-Mart Heiress Returns USC Diploma

Wal-Mart Heiress Returns USC Diploma: "Elizabeth Paige Laurie's name was on a sports arena when a former University of Southern California roommate alleged the Wal-Mart heiress paid her $20,000 to do her homework. Now it isn't even on a USC diploma.

Laurie, the granddaughter of Wal-Mart co-founder Bud Walton, has returned her degree, nearly a year after Elena Martinez told ABC's '20/20' that she had written term papers and done assignments for Laurie for 3 1/2 years. "
