💙🐾It is with heavy hearts that we announce the passing of retired Cass County Deputy K-9 Zena.

K-9 Zena faithfully served alongside Corporal Chad Thompson from 2016 to 2021, dedicating her career to protecting our communities and supporting the Cass County Sheriff's Office mission. Throughout her years of service, K-9 Zena was a trusted partner, a loyal teammate, and an important member of our law enforcement family.

Following her retirement, K-9 Zena was adopted and cared for by Corporal Jonathon Dodge, who ensured she enjoyed the comfort and companionship she deserved after years of dedicated service.

This morning, Zena passed away peacefully at Valley Veterinary Hospital, surrounded by Corporal Dodge, Corporal Thompson, and members of our patrol staff.

Today, we remember a faithful deputy, trusted partner, and cherished companion. We are grateful for K-9 Zena's years of service and the impact she made on our organization and the communities we serve.

Please keep Corporal Thompson, Corporal Dodge, and all those who knew and loved Zena in your thoughts.

Rest easy, Zena. Your watch has ended, but your legacy will live on. 💙🐾

Second Arrest Made in Cass County Jail Narcotics Investigation

CASS COUNTY, N.D. (June 4th, 2026) – An investigation that began in April of 2024 into the suspected trafficking of a controlled substance within the Cass County Jail has resulted in a second arrest. The investigation was initiated after information was received indicating that the controlled substance was attempting to be introduced into the jail through the inmate mail system. A Cass County deputy assigned to the United States Postal Inspection Service (USPIS) conducted a lengthy investigation into the allegations.

In November of 2024, 32-year-old Amar Kovacevic pleaded guilty to Conspiracy to Deliver or Possess with Intent to Deliver a Controlled Substance in a Correctional Facility. Amar was sentenced to the Department of Corrections and Rehabilitation to a term of ten (10) years, first must serve forty (40) days, followed by a period of probation.

In October of 2024, a warrant was issued for 34-year-old Daria Renville for her alleged involvement in the case. On May 13th, 2026, Renville was arrested in South Dakota and was subsequently transferred to the Cass County Jail.

Sheriff Jahner commended the collaboration between the Cass County Sheriff’s Office and the USPIS Task Force, whose work was instrumental in advancing the investigation. Sheriff Jahner said, “Whether narcotics are being trafficked outside of the jail or inside of it, holding individuals accountable will always remain a top priority. When it relates to narcotics trafficking, we will always prioritize protecting not only those within our correctional system but also the safety of our entire community. This case is another example where countless hours and sustained effort paid off and eliminated anyone getting hurt.”

No additional information will be released at this time.

Amar Kovacevic
• 32 years old
