A Natrona County man pleaded guilty to felony marijuana possession and a firearms charge, with the possibility he might serve a seven- to eight-year prison sentence.

Jeffrey Hallock entered the pleas during his arraignment Thursday before Natrona County District Court Judge Thomas Sullins.

In exchange for the pleas, Assistant District Attorney Trevor Schenk and Hallock's public defender Joseph Cole said they would agree to the dismissal of a third count, and that the federal government would dismiss its charge of Hallock being a felon in possession of a firearm.

Federal court records confirmed that charge has been dismissed.

The prosecution, defense and Hallock also agreed he would serve a four-and-a-half to five-year prison term for the felony marijuana possession count and a two-and-a-half to three-year prison term for the felon in possession of a firearm charge. The terms would be served consecutively, Schenk and Cole said.

A judge is not bound by a plea agreement.

Hallock will be free on bond pending his sentencing date, which will be scheduled later, Sullins said.

The case started during the summer when a sheriff's investigator received information from a confidential informant that Hallock had substantial quantities of marijuana in his house.

The Natrona County Sheriff's Office obtained a search warrant, and executed it at Hallock's residence in the area of Quartz Circle off North Cole Creek Road near Evansville on Nov. 3.

Law enforcement officials found a shotgun, containers with 94 ounces of marijuana in bud form, liquid THC (the psychoactive ingredient in marijuana), butter THC in plastic bags in a freezer, and cookies with THC.

They also found two digital scales and a small spiral notebook with pay/owe information about drugs, cash amounts, groceries and other items.

On Nov. 28, the Wyoming U.S. Attorney's Office took over the case specifically on the charge that Hallock was a felon in possession of a firearm.

He was convicted of second-degree murder in 1984, and was convicted of felony possession of a controlled substance in 2005, according to court records.
