The attack was captured on video, and the footage spread widely on social media as amateur sleuths set out to identify the assailants. Two remain unidentified, but three others have been arrested: Alex Michael Ramos, 34; Daniel P. Borden, 18; and Tyler Watkins Davis, 50.

A trial for Mr. Ramos began on Wednesday. Mr. Borden’s trial is scheduled for June 5, and Mr. Davis’s is set for July 16.

A lawyer for Mr. Goodwin, Elmer Woodard, did not immediately return a phone call seeking comment.

S. Lee Merritt, a lawyer for Mr. Harris, said in a statement the verdict was vindicating, but criticized the lack of hate crime charges.

“If hate crime charges were not appropriate in this case, it is difficult to imagine a situation in which such charges would be appropriate,” he said. “These shortcomings will be addressed in the civil litigation our office will move forward with at the completion of these criminal matters.”

During the trial, Mr. Goodwin and his lawyer argued that he had acted in self-defense. Mr. Goodwin said he thought Mr. Harris was running at him, so he kicked him.
