UPLAND, Neb. -- An Upland man has been sentenced to 9.5 years in prison for being a felon in possession of firearms. 

The Acting U.S. Attorney announced that 57-year-old Donald Greuter Jr. was sentenced on June 29 to 114 months in prison after he was convicted for being a felon in possession of firearms. 

After completing his prison sentence, Greuter will serve three years on supervised release. There is no parole in the federal system. 

Court documents said that in December of 2019, Greuter was on parole for a felony drug distribution conviction, prohibiting him from possessing guns and ammunition. 

On Jan. 8, 2020, law enforcement went to Greuter's home in Upland to do a parole search of his property. At the time, he was living with his significant other, Tricia Easley. 

While investigators were at his home, they said they learned that he also owned the property next door, which contained a house. 

Greuter said that he owned the property and gave investigators keys to enter the house.

Once law enforcement entered the building, they said they saw several containers of live ammo in various calibers. 

In the same room, officers said they saw a large combination safe that was locked. In between the safe and the wall, officers said they found two 12-gauge shotguns inside the gun case. 

Investigators got a search warrant for both properties and recovered over 30 firearms, including eight pistols, eight shotguns, 16 rifles and several thousand rounds of ammo. 

Among the guns that were found in the safe a short shogun, a defaced rifle, two stolen guns, a 50-caliber rifle, and three semiautomatic rifles with high-capacity magazines. 

Investigators said, in total, they found 32 guns and more than 4,000 rounds of ammo. 

Four of the guns that were recovered were found to have been purchased at a Grand Island pawn shop. 

Officials said that Easley bought these firearms because he asked her to and she took them to him. 

He gave her the money to pay for the guns and told her to pick them up from the pawn shop.

Greuter was with her more than once, when she bought the guns. 

Pawn shop employees, who were familiar with Greuter said they saw him hand at least one of the guns that was bought. 

The court said that a special agent for the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) examined the guns and ammo, and found that they were manufactured outside of Nebraska. 

Easley pleaded guilty to transferring a firearm to a prohibited person and is set to be sentenced on Aug. 2. 

This case was investigated by the Nebraska State Patrol and the Trident Drug Task Force, which is made up of officers from the Grand Island Police Department, Hall County Sheriff, Hastings Police Department, Adams County Sheriff, Kearney Police Department, Buffalo County Sheriff, Nebraska State Patrol, Homeland Security Investigations, and the FBI.
