The sheriff's office released a composite sketch. At one business in that community, a warning about the dangerous man is written on an employee bulletin board.
"It's like a big thing that we need to let all our clients know," said Megan Coller who works at Winning Image Salon and Day Spa in Stafford.
Authorities believe the police impersonator is very familiar with the areas he's targeting. He first surfaced in January and struck twice ten days apart near the sheriff's office. He uses a dark, unmarked police-like car, sometimes with red emergency lights.
The first woman he stopped got sick and he drove off. In the second case, a teenager met a violent fate.
It was on a secluded stretch of Hope Road just before sundown that authorities say the impersonator ordered a young girl out of her car then sexually assaulted her.
In the most recent case February 6 in rural western Stafford, two teenaged girls got away unharmed.
"You get caught off guard you don't when you see lights you expect it to be a police officer so you do pull over," said Coller.
Her friend, Amy Russell, keeps mace on hand just in case.
"Some times I wonder if I should carry more than just mace around it's that scary right now," said Russell.
The Stafford Sheriff's Office says its important to keep in mind law enforcement vehicles have blue emergency lights or a combination of red and blue lights.
Anyone with information about these crimes is asked to call the Stafford Sheriff's Office at 658-4400.
