Gwinnett County police on Monday appealed to the public for help solving the slaying of a Hertz Rent-a-Car employee who was found fatally wounded behind the rental car office next to the Gwinnett Transit Center.

Monique Marlowe, 24, of Duluth was cleaning a car between 5 and 5:30 p.m. Friday when a young man wearing a light blue shirt approached her, police said. For unknown reasons, the man shot the victim once and fled the area.

Marlowe was founded wounded by her co-workers and taken to Gwinnett County Medical Center, where she died as a result of her wounds Friday evening.

Maria Marlowe, the victim’s mother, told Channel 2 Action News that her daughter loved swimming and had graduated in 2009 from the University of Georgia at Athens with a degree in international business.

“I don’t know of any enemy that she had, nobody that didn’t like her,” the mother said.

The Hertz office is near the intersection of Satellite Boulevard and Merchants Way, next to the Transit Center’s pick-up and drop-off hub for bus passengers. The location is across from the Gwinnett Place Mall shopping center.

“Since the incident took place, the homicide unit has been working around the clock following up on all leads,” Gwinnett police said in a news release Monday afternoon. “Based on the time of day and location, investigators believe that someone in the area of the bus depot most likely saw the incident.”

Anyone at the location around the time of the incident who may have seen anything unusual or suspicious was asked to contact police by calling 911 or 770-513-5333.
