A Benton County jury on Thursday convicted a Glendorado man of numerous felonies, including seven counts of attempted murder of a police officer, for a shooting in 2023 that injured five members of the Sherburne County Drug Task Force, said Sheriff Joel Brott.

Karl Thomas Holmberg, 66, also was convicted of assault and drug charges.

“We are grateful for the verdict, and we hope this sends a message that the reckless violence he chose that day cannot be tolerated,” Brott said.

Members of the Sherburne County Drug Task Force in October 2023 went to a home in Glendorado Township with a narcotics search warrant. After knocking and announcing they had a warrant, Task Force members entered Holmberg’s residence. Holmberg immediately began firing gunshots at Task Force members, hitting five officers.

They left the home and called negotiators, who hours later convinced Holmberg to come outside.

One of the officers shot during the incident was hospitalized for his injuries. Other officers were spared significant injuries because they were wearing body armor.

“This incident highlights the potential dangers law enforcement officers face every day,” Brott said. “We are extremely fortunate that the injuries sustained by these brave officers were not more serious.”

Sherburne County Drug Task Force is comprised of deputies from Sherburne County and officers from the Elk River and Princeton police departments. Benton County deputies assisted with the execution of the initial warrant.

Sheriff Brott wants to thank all of the law enforcement agencies that responded to the shooting as well as all agencies that investigated it and prosecuted the suspect.
