Reward grows to $100,000 in Gwinnett Co. cold case murder

DULUTH, Ga. (AP) The family of a Hertz Rent-a-Car employee who was gunned down at her suburban Atlanta job site has been increased to $100,000.

Authorities say 25-year-old Monique Marlow was cleaning out a car at the business in Duluth when she was shot in September 2012.

Police on Tuesday announced that Marlow's family had come up with an extra $50,000 to add to the $50,000 reward Hertz is offering.

Marlow's relatives say they believe one key to finding the killer could be a missing sliver necklace Marlowe often wore. The necklace includes a mouse ear pendant.

Marlow was a 2009 University of Georgia graduate.
