At about 2:30 a.m. Tuesday, security cameras captured a gunman entering the Walgreens at Groesbeck Highway and Utica Road in Fraser.
The video shows him sneaking up to ambush the young clerk who was working in one of the aisles. He stuck the gun to her back and forced her to the register.
The register was packed with cash, and the robber grabbed all of it. The clerk helped him pick some of it up as it fell on the floor.
The 22-year-old was working overnight at the Walgreens. A pharmacist was working in the back, but the clerk was alone up front.
"She's probably going to remember that for the rest of her life," said Fraser Police Lt. Dan Kolke.
This is the first armed robbery reported in Fraser in a year. However, there have been multiple armed robberies in Detroit suburbs this summer, many at 7-Eleven stores.
"It's because of drugs. People are really involved in heroin and they're doing whatever they can do to get the money," said Kolke.
The safety of the young clerks working overnight without much security is a huge concern.
"She's never been assaulted with a gun, thank God," said a man whose daughter works at the Walgreens in Fraser.
He's definitely worried about her safety.
"All you can do is be on your toes and be glad when you go home that night," he said.
