Rumors of a “shooter” in Nashville this morning are false.

At around 11 a.m., Brown County dispatch received a call from a county building about a man with a handgun in the area of the old log jail downtown.

Police had been looking for him as a precaution. It’s unclear if he was simply carrying a gun legally.

Nashville Police Chief Ben Seastrom said nothing was going on; a Twitter post appeared to have stirred up concern which spiraled into a false rumor of a shooter.

In the meantime, the County Office Building and courthouse — where a murder trial is going on this morning — were on “semi-lockdown” as a precaution, as well as the fairgrounds, according to newspaper reporters at the courthouse and the fairgrounds.

Judge Judith Stewart announced the situation in the courtroom and advised people to stay in the building as a precaution for the time being. It could easily be a legal open-carry situation, she said.

The doors of the courthouse were locked, but otherwise it was business as usual.

Police were unable to find the man.
