Prosecutors charged Wilberg on Monday in 8th District Court with having a firearm as a restricted person due to his prior conviction which is a third-degree felony that carries a potential sentence of five years in prison.
He also was charged with possession of drugs and drug paraphernalia, discharge of a firearm and intoxication, which are misdemeanors.
On Feb. 6, a Duchesne County sheriff's sergeant and a detective arrived at Wilberg's home about 1:45 p.m. after someone heard gunshots and called 911. Wilberg told them that he had taken his dog outside and shot it with a .357-caliber magnum pistol, then put the dog in the garbage can and shot it again so it would not suffer.
While talking with Wilberg, the pair noticed a pipe with marijuana residue in it, according to the charges. When the detective asked him about, Wilberg showed them a prescription bottle that contained a few marijuana buds.
They also noticed alcohol on his breath, and Wilberg told them he had had four shots that day.
They arrested him and took him to jail, where a test showed he had a blood-alcohol content of 0.137, the charges add.
They booked him into the jail on Monday, though he has since been released on $1,591 bail.
He's scheduled to make his first court appearance on Feb. 28.
