Missouri - The Missouri State Highway Patrol is warning residents about a person or persons impersonating an officer.

MSHP Corporal Dustin Reed said there has been two similar reports of someone impersonating an officer, and they have an active investigation going.

On June 8 at 9:41 p.m. a 24-year-old woman was driving southbound on U.S. 67 in Jefferson County when an unknown model, dark-colored passenger car began to follow her and activated alternating red and blue flashing lights.

Thinking it was a police officer, the woman stopped on U.S. 67 at Buck Creek Road and the suspect approached her vehicle trying to open the rear door of the car. She described the person as approximately 5’10 in height with a stocky build, wearing a black ski mask, gloves and a dark hoodie.

The woman was able to grab her pistol and point it at the man. The person went back to their own vehicle and when he opened the door the dome light came on and illuminated a person in the front passenger seat as well. The man then drove off north on Buck Creek Road.

Another report was made of a similar incident on June 10 at 4:40 a.m. This time a 19-year-old girl was driving east on Highway 32 in St. Francois County when an unknown model white or silver SUV or passenger vehicle pulled behind her near the intersection of Route B.

The driver of the other vehicle activated alternating red and blue flashing lights and, thinking it was a police officer, the girl stopped on Highway 32 just east of Route B.

The young woman saw the person in the car with the lights approaching her car and he was wearing a black ski mask, red hoodie and possibly gloves, and was holding a large flashlight.

The suspect was described as being about 5’11 tall with a stocky build. She drove off quickly but saw the suspect make a U-turn and head west on Highway 32.

Reed said as of Friday it was an ongoing investigation, and warned if someone does encounter someone they think might not be a real police officer, they should slow their speed, turn on their hazard lights and call 911.

If anyone has any information on either incident, or may know who was involved, they are asked to contact a local police or sheriff's department.
