The Meade County State's Attorney said Friday that members of the Hells Angels initiated a bar scuffle that led to the shooting of one of club's members at the Loud American Roadhouse in Sturgis earlier this month.

Meade County State's Attorney Jesse Sondreal said in an e-mail that the investigation has revealed the Hells Angels "instigated the assault" in a fight with the Iron Pigs on the evening of Aug. 9.

The two clubs got into a fight just before the shooting, according to witnesses at the scene and authorities. The Iron Pigs is a national motorcycle organization made up of police and firefighters.

Seattle Police Detective Ronald Smith, an Iron Pig member, has admitted to shooting Hells Angel member Joseph Patrick McGuire, who was hospitalized after the incident. But Smith, 43, said in newspaper interviews that he was attacked by a group of Hells Angels and that he fired at McGuire in self-defense.

McGuire was hit twice.

Both McGuire and Smith have been charged by a grand jury with felony aggravated assault and a misdemeanor alternative count of simple assault. The men can only be convicted of one of the charges.

Smith is also charged with perjury - a felony - and carrying a concealed pistol without a permit, which is a misdemeanor.

No other details on the altercation have been released.

The Iron Pigs is a motorcycle club made up of police and firefighters. Three other Iron Pigs have indicted on weapons charges, as has one other man with unknown affiliations.

But the 33-year-old McGuire, an Imperial Beach, Calif. native, is the only confirmed Hells Angel to face criminal charges.

Sondreal said that others could "possibly" be charged in the case.

The other men who were charged include Scott Lazalde, 38, of Bellingham, Wash.; Dennis McCoy, 58, of Seattle; Erik Pingel, 35, of Aurora, Colo.; and James Rector, 37, Ferndale, Wash.

Each was indicted for carrying a concealed weapon without a permit or an alternative charge of failing to abide by a permit of a reciprocal state. They can be convicted of just one of the charges. Both are misdemeanors.

Lazalde and Rector are members of the U.S. Customs and Border Inspection in Blaine, Wash. McCoy is a precinct patrol sergeant in Seattle.

Pingel's occupation and motorcycle club affiliation were not known.

McGuire's medical condition is unknown, as he is not listed in the directory at Rapid City Regional Hospital. However, one of his relatives told a Seattle newspaper that McGuire had been taken out of intensive care and was recovering from gunshot wounds in his stomach and leg.

A grand jury convened for about seven hours on Aug. 10, interviewing 25 people about what happened in the moments leading up to the shooting. They gathered again Wednesday and signed the indictments later that day.

Smith and McGuire could face up to 15 years in prison if convicted of aggravated assault, and Smith could face up to 5 years in prison on the perjury charge. Both charges are felonies.
