The man arrested Friday for growing marijuana at his residence near Evansville was convicted of second-degree murder in 1984, according to affidavits filed in Natrona County Circuit Court.

Besides being charged with felony possession of a controlled substance, Jefferey Hallock also was charged with being a felon in possession of a firearm, according to court documents.

Hallock heard the felony charges during his initial appearance in circuit court on Monday, and he will have a preliminary hearing within a few weeks to determine whether he will be bound over for trial.

A press release from the Sheriff's Office on Friday said Hallock (court records differ whether his first name is spelled Jeffrey or Jefferey) was arrested after deputies executed a search warrant at a residence in the area of Quartz Circle off North Cole Creek Road near Evansville.

Deputies recovered 11.18 pounds of marijuana, grow lights, chemicals and a firearm, specifically a 12-gauge shotgun and at least three boxes of 12-gauge ammunition, according to an investigator's affidavit requesting a search warrant.

Hallock admitted the shotgun belonged to hm and he had a person buy it for him for $250, according to the affidavit.

Hallock was convicted of second-degree murder in 1984, and also was convicted of felony possession of a controlled substance in 2005, according to the affidavit.

The Sheriff's Office had been investigating Hallock's residence since late July, and sources reported Hallock grew marijuana, processed it in the rear of his residence, and recently installed vents to remove the odor from building. Hallock also installed air fresheners in the electric outlets.

A confidential source told a sheriff's deputy that Hallock would deliver the marijuana to his customers on Friday mornings after 7 a.m. "because Hallock wanted to get his customers on pay day."
