Minnesota Police Sergeant and Father of Two Dies Suddenly from Brain Infection

Minnesota K9 Officer Dies Less Than 24 Hours After Brain Infection Diagnosis

A northern Minnesota police sergeant and dedicated father of two has tragically passed away less than a day after receiving a devastating medical diagnosis, leaving behind a heartbroken family and a community in shock.

Sgt. Cody Siebert, a K9 officer serving with the East Range Police Department, died on February 27, according to an official announcement from the department. He was widely regarded as a devoted father, a trusted colleague, and an irreplaceable presence in the small Minnesota community he dedicated his career to protecting.

A Officer Who Made a Lasting Impact

Siebert played a pivotal role in establishing the K9 program in Babbitt, Minnesota, working closely alongside his police dog, Taconite, before transitioning to the East Range Police Department. His upbeat, approachable nature made him a beloved figure among colleagues and residents alike.

"Sgt. Siebert was well known for his happy-go-lucky personality," the department shared in a Facebook tribute. "It was best said that if you couldn't get along with Cody, it was your fault."

The department further acknowledged the profound loss, stating that the void left by his passing would be impossible to fill.

A Sudden and Shocking Medical Emergency

According to his life partner, Karen Blais, Siebert woke up one morning last week complaining of a headache that had started the day before. He was quickly hospitalized, where medical professionals discovered that a nasal passage infection had spread to his brain. He died within 24 hours of that diagnosis.

His brother, Brandon Siebert, spoke about Cody's genuine passion for serving others — a commitment that went far beyond typical law enforcement duties.

"He loved people — being in that position and being able to help people in general," Brandon said. "Not just getting the bad guys, going to the school, checking in with people."

Community and Schools Honor His Memory

Mesabi East Schools also paid tribute to Sgt. Siebert, describing him as someone who recognized the potential in every student he encountered.

"The impact he had on our students and staff cannot be measured. He wasn't just our K9 officer — he was a mentor, a role model, a friend, and a steady, positive presence in our Giants community," the school district wrote in a statement.

His family echoed those sentiments on a GoFundMe fundraising page, which has already surpassed $107,000 in donations.

"To know Cody was to have a friend. He had a rare gift for connection — if you crossed paths with him, you knew you were in for a genuine conversation. He truly enjoyed people, and his absence leaves a void in our community that will be felt by many," the family wrote.

Tragedy Follows Recent Family Loss

This heartbreaking loss comes just months after another tragedy struck the extended Siebert family. Cody's sister-in-law, Alyssa Siebert, passed away in October from a brain aneurysm — a strikingly similar and devastating circumstance.

"We're in a déjà vu of an unusual situation," said another sister-in-law, Ashley Siebert. "They both helped others the whole time. They were both great people. They've done more than most 30-year-olds have accomplished in their lives."

In a final act of generosity, Sgt. Siebert chose to donate his organs — a decision that mirrors the selfless spirit he demonstrated throughout his life, much like his sister-in-law before him.

Survived by His Partner and Two Young Sons

Sgt. Cody Siebert is survived by his life partner, Karen Blais, and their two sons, aged one and two years old. Those wishing to support the family can contribute through the GoFundMe page established in his honor.
