MARIETTA, Ga. -- Friends of a slain Auburn University freshman are selling lime green wristbands in her honor to raise money for charity, including a scholarship in her name.

University of Georgia junior David Awadalla, who attended Walton High School with Lauren Burk, started selling the bracelets soon after her death. The bracelets sell for three dollars and organizers have raised more than $500 so far.

Due to the response, organizers have ordered more than seven thousand wristbands. Sales will be donated to Invisible Children and the Lauren A. Burk Memorial Scholarship at Auburn University and Oglethorpe University in Atlanta, where her parents met as students.

Burk was found suffering from a gunshot wound on a roadway about five miles from campus shortly after 9 p.m. on the night of March 4 and her car was found about 20 minutes later burning in a campus parking lot. She died that night.

Friends said that lime green was Burk's favorite color. The wristbands are also being sold through the social networking site Facebook and a memorial Web site.
