The suspect reportedly demanded the victim open the door, and she complied. That's when the armed man and a second suspect entered.
The two suspects took an undisclosed amount of money from the safe and register. But before leaving, they also took the victim's car keys and fled in her 1994 four-door red Infiniti.
The suspects are described as black males, 25-35 years of age, 5-foot-10 to 6 feet tall with medium builds. One of the suspects was wearing dark clothes and a black jacket with a gold emblem on the back.
The victim's car has not been recovered.
