Rest in peace, Deputy Katherine Frank. Thank you for your service, and prayers to your family and the entire Sheriff's Office.

Passing of Deputy Katherine Frank -

The Minnehaha County Sheriff’s Office announces with profound sadness the passing of Deputy Katherine Frank, age 26, earlier today. Deputy Frank was surrounded by her family and loved ones in her final moments. In her final act of service and generosity, she became an organ donor, continuing to help others even in her passing. Katherine worked at the South Dakota State Penitentiary from September 2022 until being hired with the Minnehaha County Sheriff’s Office in June 2024.

Deputy Frank’s death is a significant loss to our agency and to the broader law enforcement community in and around Sioux Falls. She served the citizens of Minnehaha County with professionalism, humility, and dedication. Her absence will be felt deeply by all who have had the privilege of working alongside her.

A memorial has been established at the Law Enforcement Center located at 320 W. 4th St., Sioux Falls, SD, for those who wish to pay their respects. The Sheriff’s Office will also continue maintaining a presence at the hospital as we support her family during this difficult time.
Further information regarding funeral services, honors, and departmental arrangements will be provided as soon as it becomes available.

Deputy Frank served with dignity and heart. Her service made a meaningful difference, and her impact will remain with us always.

I attended today's press briefing and spoke with a number of our law enforcement officers. Please keep the deputy who was shot, and their family, in your prayers, along with everyone involved and the entire Sheriff's Office. Our officers face this reality every day. Thank them for their service, and honor it.

Thank you to everyone who came yesterday and to those who have reached out about the county’s Flock cameras (license-plate readers). I asked the Commission to set a vote on taking them down and putting an indefinite moratorium on new ones. That motion did not pass, but the conversation on public safety versus privacy will continue, and the state legislature should take this up as well.

I’ve been getting a lot of feedback and having conversations about Flock cameras. It’s gained attention nationwide, statewide, and right here at home. Aberdeen shut the door. Codington County took theirs down. No matter where you look, the concern is real. These cameras can help with serious cases, but it is not the whole story. No matter how you slice it, this is indiscriminate government surveillance. Every car that drives past gets photographed.

I want to be clear: this is nothing against law enforcement. I have great confidence and trust in our Sheriff, our deputies, and our Sheriff’s Office staff. I question whether this much power should be in the hands of the government. We should not be afraid of technology, but we should take a step back and ask what kind of world we want to live in. I believe I can speak for most people here: we do not want a total surveillance state.

Too often the voice of the people falls on deaf ears. I was elected to represent the people of this county. With the groundswell of opposition we are seeing from regular citizens from all walks of life, I will be looking to propose a resolution to consider an indefinite moratorium on the county’s Flock cameras and license-plate readers. I also hope it generates a broader conversation, and I look forward to the state legislature grappling with this next session.

It is with great sadness that we share the news of Corporal Kevin Keegan’s passing. He passed away unexpectedly on Monday evening at the hospital due to a sudden medical event. Kevin dedicated over 19 years of service to the Sheriff’s Office within the Jail, and his commitment, professionalism, and presence will be deeply missed. Please keep Kevin’s family, friends, and colleagues in your thoughts during this difficult time.
