On December 11, 2025, Deputy Jeremy Johnson was riding with Investigator Brian Mattson in his unmarked squad. Both individuals are members of the AIMVCET Drug Task Force. At approximately 12:30 P.M. The agents traveled past a house in the City of Cohasset that was being monitored for controlled substance crimes. They observed a black Chevrolet Silverado pick up parked in the driveway with a person in the driver's seat. The license plate on the vehicle was snow covered/obstructed. It had not snowed that day and the roads were clear.
The two agents later followed the pickup to the public access on the Mississippi River near Minnesota Power in Itasca County. At approximately 12:35 P.M., Investigator Mattson pulled his squad up next to the driver's side of the pickup, but did not activate the emergency lights, nor block the pickup in. Agent Mattson approached the male driver, later identified as Luke Grossman, and identified himself. Meanwhile, Deputy Johnson approached the passenger side window of the pickup, at which time he observed a glass smoking device with white residue resting on the center console with a plastic baggie containing a white substance next to the pipe.
Based upon his training and experience, Deputy Johnson believed the white powdery substance to be methamphetamine (Schedule II Controlled Substance). There was a female in the front passenger seat, later identified as Taylor Caitlin Nason. When Agent Mattson notified the driver of the obstructed license plate, the driver exited the vehicle to wipe the snow from the license plate. During that timeframe, Deputy Johnson photographed the pipe and methamphetamine that were in plain view. The driver stated that they were coming from his mother's residence.
When Deputy Johnson asked him how much methamphetamine was in the vehicle, Grossman denied knowledge of any methamphetamine inside. Deputy Johnson then pointed out the bag and smoking device on the center console, in which Grossman claimed he did not know the items were there. When Deputy Johnson confronted him with the fact that the items were in plain view sitting right next to him, he still denied knowledge of them. Meanwhile, Investigator Mattson began speaking with Nason. It should be noted that Nason's face had numerous scabs and sores on it, some appearing freshly picked.
Based upon his training and experience Deputy Johnson was aware that his observations were consistent long term methamphetamine use. Additional law enforcement officers soon arrived at the scene. 3 31-CR-26-58 Filed in District Court State of Minnesota 1/8/2026 A record check revealed that Grossman's driving privileges were revoked.
