A Forest Knolls man was arrested on allegations he shot a man with a BB gun in an argument over whether to have a barbecue.

Terrance Lee Osborne, 51, was booked into Marin County Jail on suspicion of assault with a deadly weapon and exhibiting a weapon. His bail was set at $50,000.

The incident occurred Saturday afternoon on Montezuma Avenue, where a resident reported that a man was firing a shotgun at some people in the park.

Sheriff's deputies arrived and determined that Osborne had fired a BB gun at a 45-year-old Lagunitas man, said sheriff's Lt. Jamie Scardina. The shooting allegedly occurred because the victim wanted to have a barbecue and Osborne did not.

Osborne was taken off to jail. The alleged victim, Woody Wilson, did not require medical treatment.

In an interview Monday, Osborne's longtime girlfriend, Toinia Vigneri, confirmed that Osborne fired the gun, but she said Wilson was badgering them to have a barbecue in the park. Osborne and Vigneri live across the street from the park.

"Terry and Woody are basically friends -- frenemies -- you know, friends," she said. "They don't mean to fight."

On the day in question, Osborne and Vigneri were just getting up from a nap.

"I don't know where Woody got this barbecue thing," she said. "He just came up and said we're going to barbecue. They have got no grill, no food, no charcoal, no anything. He expects us to, I don't know, get dressed and go shopping for him, drag our grills over to the park and do everything for him.

"There was not going to be any barbecue."

Finally, Osborne pulled out a Daisy pellet gun and fired it two or three times at Wilson, Vigneri said. Wilson came to the house and informed Osborne that a BB struck him in the leg.

"He wasn't mad about it," she said. "He just wanted to tell him that one of the BBs hit him. They laughed about it and high-fived about it."

But by then, sheriff's deputies were on the way.

Wilson, reached by telephone, denied that he was even shot.

"I've known Terry all my life pretty much and I have no hard feelings toward him," Wilson said.

He said they try to get together for barbecue about once a month.

Prosecutors reviewed the case Monday and filed a misdemeanor brandishing charge against Osborne, but not the felony assault charge.
