A Minnesota State Trooper has been federally charged with the production of child pornography.

State Patrol Chief Christina Bogojevic called the allegations “appalling and indefensible,” saying it was a serious violation of the law and human decency.

Bogojevic said an internal affairs investigation is underway and Plonski is on leave. He joined the State Patrol in 2022.

FBI Special Agent in Charge Alvin M. Winston Sr. described the allegations as “a gross betrayal of public trust” and that law enforcement officers are expected to protect children, not exploit them.

“When someone in a position of authority commits such an egregious and despicable crime, the damage extends beyond the victim — it shakes the very foundation of our communities’ trust,” Winston said.

The investigation was led by the FBI’s Minneapolis Field Office, with support from the Minnesota Bureau of Criminal Apprehension and the Shakopee Police Department. The Minnesota State Patrol also assisted in Plonski’s arrest.

Minnesota BCA Superintendent Drew Evans echoed the sentiment, pledging the agency’s continued commitment to identifying and prosecuting individuals who harm children.

Plonski remains in federal custody pending a detention hearing, which has not yet been scheduled.
