Wal-Mart Heiress Returns Diploma

Granddaughter Of Wal-Mart Co-Founder Allegedly Paid For Schoolwork

(AP)  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 ½ years.

"Paige Laurie voluntarily has surrendered her degree and returned her diploma to the university. She is not a graduate of USC," the school said in a statement dated Sept. 30 but not widely disseminated until the school newspaper wrote about it late last week. "This concludes the university's review of the allegations concerning Ms. Laurie."
