A July 4 traffic stop in the village of Lannon turned surreal when a driver allegedly cut off a marked police cruiser, flashed what he claimed was an FBI badge, then took off, triggering a closer look from law enforcement. Two days later, officers arrested the man and charged him with impersonating an FBI agent and driving while his license was revoked.

According to WISN, a criminal complaint identifies the suspect as Jeffrey Wertz and alleges he pulled his vehicle in front of a marked Lannon police squad, got out, showed the officer a badge and then drove away. When officers later searched Wertz's home, they allegedly found a gold badge stamped "Federal Bureau of Investigation Department of Justice," the complaint states.

"The facts in here give me great concern. Impersonating an FBI agent, allegedly, is a very serious offense, which is why it is a class I felony," prosecutor Alina Flink told WISN. The outlet reports that the criminal complaint forms the basis for the state charges now filed against Wertz.

How Officers Say It Unfolded

The complaint states that Wertz steered his vehicle in front of the marked patrol car and climbed out to talk with the officer, a move the officer described as out of the ordinary. Police noted it is highly unusual for an off-duty person to flag down an on-duty officer in that way without a clear reason, which helped spur the follow-up investigation.

Legal Consequences

Impersonating a federal agent can also be treated as a federal offense. According to the U.S. Department of Justice, false impersonation under 18 U.S.C. a7 912 can carry up to three years in prison and financial penalties in some cases. State law separately criminalizes impersonating public officers and similar conduct; prosecutors may pursue state charges based on the specific facts, as outlined in the Wisconsin statutory elements.

What Happens Next

Wertz was taken into custody on July 6 and now faces the counts listed in the criminal complaint. Upcoming court proceedings will determine how the case advances. Prosecutors could add charges if new evidence surfaces, and federal authorities could step in if investigators conclude federal laws were violated.

Local Context

In recent months, local and county law enforcement agencies have warned residents about impostors and bogus badges, saying the scams chip away at public confidence in real officers. The county recently alerted the public to a spike in impersonation phone scams, which makes alleged face-to-face impersonation on neighborhood streets especially troubling for both police and prosecutors.
