Dane E. Gallion pleaded not guilty Thursday to third-degree assault in a shooting Jan. 21 at Regal Cinemas at The Landing in Renton that wounded a movie-goer in the shoulder.

Gallion, 29, of Newcastle was charged on Jan. 26; he had posted bail on Jan. 23. His next court appearance is March 22.

A bullet fired from the 9mm Smith and Wesson handgun that Gallion had with him, striking 40-year-old Michelle Mallari after it pierced the back of the seat, according to charging documents.

She was transported to Harborview Medical Center in Seattle with a broken clavicle.

“Obviously, Mr. Gallion feels terrible about it,” said his attorney, David Allen, after his arraignment at the Norm Maleng Regional Justice Center in Kent. “Mr. Gallion is tremendously remorseful; he’s very very sorry.”

Allen declined to answer a question why Gallion brought a gun into the theater.

“That is something that’s going to have to wait until we get into the area where we are litigating this, if it does go to trial,” he said. “But I will say that my client did have a concealed weapons permit to carry a firearm.”

Allen said the third-degree assault charges reflect that the shooting was an accident.

“It does, exactly. It talks about criminal negligence and that’s not an intentional act. It’s a negligent act. There’s no question but it was an accident,” he said.
