An Illinois man set to become Unalaska’s next fire chief has been arraigned on sexual assault charges.

The case stems from an incident that allegedly took place at a going away party for Savoy, IL resident David Dunn, who was due in Anchorage to Monday to continue the onboarding process with the City of Unalaska, according to city manager Dave Martinson.

Instead, Dunn spent Monday in custody and was arraigned on two felony sexual assault charges, according to Champaign County State Attorney Julia Rietz.

Rietz said the attack happened on April 2, and was reported the next morning. She said the male victim was at the going away party and had consumed alcohol.

“Investigation revealed that Dunn administered an IV to the victim allegedly to provide him with medication for nausea,” Rietz wrote in a statement. “The victim reported that following the IV he was unable to move or speak and that Dunn committed acts of sexual penetration without his consent.”

Investigators spoke with Dunn about the allegations. Dunn not only confirmed the victim’s story, but also admitted to secretly putting erectile dysfunction medication in the victim’s drink prior to the assault.

Dunn was arrested and is being held on a $500,000 bail. Illinois Judge Brett Olmstead denied Dunn’s request to leave the state and Dunn’s next court appearance is scheduled for April 18. If convicted, Dunn faces between four and 15 years imprisonment for each charge.

Martinson said the news of Dunn’s arrest came as a “complete surprise.” According to Martinson, Dunn had already been hired and was to be in Unalaska shortly.

Due to the seriousness of the allegations, Martinson said it was more than likely that the city would begin the termination process. He said Unalaska Department of Public Safety director Michael Holman had been assisting with the duties of fire chief pending Dunn’s arrival, and would continue to do so until a replacement can be found.

Martinson said the city was “disappointed” by the news, adding that the position of fire chief needed to be held by someone the public could trust.
