MANTORVILLE — The Kasson-Mantorville High School Activities Director and head football coach was arrested for allegedly driving while under the influence of alcohol over the weekend.

Broc Raymond Threinen, 42, is charged in Dodge County District Court with two gross misdemeanor charges of third-degree driving while under the influence and misdemeanor open bottle.

At a court hearing Monday, Judge Jodi Williamson set unconditional bail at $12,000. Court records indicate Threinen posted bail that day. His next court appearance is scheduled for Oct. 2.

Threinen was stopped by law enforcement just after 1:50 a.m. Saturday after an officer on routine patrol saw an SUV drifting within the lanes of travel, nearly leaving the roadway, according to court records. Threinen told law enforcement that he was going home from a friend's house in Kasson.

While speaking with Threinen, law enforcement allegedly noticed his speech was slurred and mumbled and that his eyes were glossy. An open can of Coors Light was in the vehicle's center console cup holder, according to court records.

Threinen allegedly denied drinking when first questioned but later said he stated "a couple of beers," according to court records. 

Standard field sobriety tests were conducted as well as a preliminary breath test, which reportedly found Threinen's blood alcohol content at 0.193, nearly an hour after the initial stop. The legal limit is 0.08.

Threinen has been placed on administrative leave for the remainder of the season for his coaching duties and on administrative leave until Oct. 10 for his activities director position, Kasson-Mantorville Schools Superintendent Mark Matuska wrote in an email.

Threinen is in his 20th year with the school district.

This is Threinen's seventh year as Kasson-Mantorville High School's head football coach. The team's defensive coordinator, Joel Swanson, will be interim coach, Matuska wrote.

"With Joel's previous varsity coaching experience, we are confident in his and the rest of the coaching staff's ability to represent the KoMets well at all levels of our program," Matuska wrote. "Activities director responsibilities will be shared by Trent Langemo, our high school principal, and Josh Larsen, our middle school principal. I am extremely confident in their abilities to continue to add value to our many successful programs at KM during this time frame."
