Two suspects in a Brownsdale theft ring pleaded not guilty to their respective charges Thursday.

John Charles Dehoff, 28, and Shane Thomas Rose, 37, pleaded not guilty to drug and possessing weapons as a felon charges, respectively.

Both men were arrested as part of a raid on a shed, home and several vehicles in Brownsdale on July 26 after Mower County Sheriff’s deputies received burglary evidence by Mitchell County law enforcement.

Two other men were also arrested during the raid. Troy Arther Leeper, 40, was found sleeping in a car near the shed where the others were arrested. A fourth suspect was also arrested and has yet to be charged in Mower County.

Deputies recovered stolen tools, guns and drugs from the shed, including one gun hidden in the walls in Rose’s office next to “elaborate surveillance equipment,” according to the complaint.

Police also found electronic equipment, including several cell phones, memory cards and digital cameras, inside Rose’s truck.

Deputies eventually searched Rose’s home at the 100 block of Cedar Street Northwest and several other vehicles, where they found even more stolen contraband.

Further charges are expected for all four suspects as the investigation continues.

Rose has been charged with four counts of possessing firearms as a convicted felon.

He has several felony drug convictions, including a third-degree conviction in 2010. Dehoff was charged with third-degree drug possession.

Leeper was charged with possessing firearms as a convicted felon and fifth-degree drug possession. He also has a previous felony conviction from 2007.

Mower County Sheriff Terese Amazi said earlier this week that the investigation could take months as law enforcement sifts through thousands of stolen goods. Thus far, deputies have connected stolen goods to burglary reports in at least five counties: Mower, Steele and Goodhue counties in Minnesota, and Mitchell and Worth counties in Iowa.
