CHARLES CITY — Charges against a Nashua woman accused of serious injury by vehicle after an accident in Floyd County in 2021 have been dropped.

A criminal complaint stated that 47-year-old Carey Agnitsch of Nashua was driving on Timber Avenue in Floyd County on July 26th of 2021 while doing her job as a rural route postal carrier when she collided with a semi at the intersection of 270th Street. Investigators stated the semi had the right of way, nothing blocked the view of the intersection, but there were no signs of braking or any attempt by Agnitsch to slow down before the collision.

The complaint says Agnitsch and a passenger had to be extracted from the vehicle with both being taken to the Mayo Clinic hospitals in Rochester for treatment, with the semi driver not being hurt. Investigators say a state patrol officer stated Agnitsch had a history of illegal drug use and that she tested positive for drugs while being treated at Mayo for her injuries.

Agnitsch pleaded not guilty to charges of serious injury by vehicle, a Class D felony punishable by up to five years in prison, as well as OWI first offense.

Before her trial was scheduled to start late last week, the charges were dropped after the judge ruled that the drug test done on Agnitsch as well as a witness who was a Mayo Clinic laboratory employee would not be allowed during the trial.

The Floyd County Attorney’s Office moved to dismiss after the judge’s ruling.
