The St. Johns County Sheriff’s Office is warning residents of at least two incidents in which women appear to have been pulled over by someone impersonating a law enforcement officer on Interstate 95 in recent days.

“While there are similarities in the occurrences, there are also differences in the suspect descriptions,” the Sheriff’s Office said in a Wednesday news release.

In the first incident, a female nurse with a “Jacksonville area hospital” was traveling north on her way to work from St. Johns County when she was stopped by a vehicle with red and blue lights, the release said.

The woman described the man who approached her car and asked for her license as a white male in his 50s with a shaved head or very short hair. He was wearing a tan uniform with a name tag that said “Moyer” or possibly “Moer.”

The woman said she did not see a gun or gun belt and that the man told her he was from St. Johns County and advised of the cost of the ticket, which the Sheriff’s Office said was an inaccurate figure.

“The subject ended the conversation by saying she could ‘consider this a warning’ and handed her license back to her after studying it,” the release said.

The woman said she reported the stop because it seemed out of the ordinary and the subsequent investigation revealed that the incident happened a short distance north of the Duval County line.

A few days later, another female nurse reported a similar incident in the southbound lanes of I-95 in St. Johns County.

The woman was headed home from work from a Jacksonville hospital, when she stopped for a vehicle displaying red and blue lights “apparently mounted at the top of the windshield,” the release said.

The woman described the vehicle that stopped her as a dark colored Chevrolet four-door sedan that pulled up beside her before falling back and turning on the lights. The release said that she described the man who approached her vehicle as “a thin framed, shorter black male … wearing rimmed glasses, a blue striped polo shirt and a black hat.”

She said the man had a plastic tag around his neck that said “JSO Detective” and that he identified himself as a Jacksonville detective. He told the woman he stopped her for speeding and asked for her driver’s license. She told the Sheriff’s Office that he did not show a badge or any identification and did not appear to be armed with a firearm. After returning her driver’s license, the suspect vehicle exited onto County Road 210 and was not seen again.

The Sheriff’s Office is reminding residents that its deputies do not wear tan uniforms and says that it does not have a deputy by the name of “Moyer” or “Moer.”

“As a best practice,” the release said, “if you are in an isolated area or have concerns of a stop, turn your hazard lights on and safely begin to drive to a well-lit and populated area.”

If concerned about a stop, the release suggests calling the local enforcement agency with a current location and asking if it is an actual officer initiating the stop.

“If you do not have the number already stored in your cell phone (you should) 911 may be appropriate,” the release said. “Additionally, law enforcement officers will possess an official badge and wallet credentials when performing their duties and will generally already have them displayed or readily available.”

The St. Johns County and Jacksonville sheriff’s offices are still investigating the two incidents.

Anyone who may have any information of the subjects mentioned or someone who may have talked about conducting traffic stops on citizens with unlawfully installed police equipment is asked to call the St. Johns County Sheriff’s Office at 904-824-8304.
