Thank you for your service, ACE 🐾
My thoughts go out to the Kohlmann family and FDL Sheriffs Department for their loss
In Memory of K9 Ace
It is with profound sadness that the Fond du Lac County Sheriff’s Office announces the unexpected passing of K9 Ace following medical complications.
Ace arrived here in August 2020, and since then, faithfully served the Fond du Lac County Sheriff’s Office and the citizens of Fond du Lac County alongside his handler, Sergeant Andrew Kohlmann. In these last six years, Ace demonstrated an extraordinary level of dedication, courage, and commitment to the community he served.
Together, Sgt. Kohlmann and K9 Ace were deployed 479 times, resulting in 496 arrests and countless instances in which Ace’s skills helped keep our deputies and community safe.
Throughout his career, Ace was responsible for helping locate and seize significant amounts of illegal drugs and other evidence, including:
• 1,347 grams of co***ne
• 1,080 grams of he**in
• 2,657 grams of methamphetamine
• 2,070 M**A pills
• More than 1,500 scheduled narcotics pills and prescription medications
• 236 paraphernalia arrests and citations
• 35 illegally possessed fi****ms seized
• More than $100,000 in drug-related cash seized
While these numbers demonstrate the tremendous impact Ace had on law enforcement and community safety, they do not tell the whole story.
K9 Ace was more than a law enforcement tool. He was a partner, a protector, and a beloved member of the Sheriff’s Office family. Behind every deployment was a dedicated dog who relied on his training and instincts, and a handler who trusted him completely. Together, Ace and Sgt. Kohlmann formed a partnership that made a lasting difference in Fond du Lac County and to our Sheriff’s Office K9 Unit. The duo’s work was an integral factor in driving the growth of our K9 program to the size it is today.
Ace worked when called upon, stood beside his fellow deputies, and served our community without hesitation. His contributions will continue to be felt through the people he helped protect, the dangerous substances and weapons he helped remove from our streets, and the countless situations in which his service made a difference.
Today, we ask the citizens of Fond du Lac County to join us in remembering K9 Ace and honoring the six years of faithful service he gave to our community.
To Sgt. Kohlmann: We recognize the tremendous bond between you and Ace and the loss that comes with saying goodbye to a trusted partner and friend. The Fond du Lac County Sheriff’s Office and the citizens you served together are grateful for everything you both gave to this community.
Rest easy, Ace. Your watch is over, and your six other four-legged partners will take it from here.
