WACO, Tex. — One year ago Tuesday, law enforcement officials here broke up one of the biggest and deadliest clashes of motorcycle gangs in the country. Gunfire erupted outside a Twin Peaks restaurant at a meeting of a regional coalition of motorcycle clubs after an altercation between two rival groups, the Bandidos and the Cossacks. So many bikers were arrested — nearly 200 — that officials used the Waco Convention Center for initial processing.

Police have said that the bikers, who attacked one another and fired on police officers, were part of “a gang-oriented criminal element” that had brought a stockpile of weapons with them. More than 300 handguns, knives, clubs and other weapons were recovered by the police.

Still, a year later, not all those trying to move on from the debacle are bikers with rap sheets.

A crowd of about 80 bikers and their supporters rallied at the steps of the county courthouse on Saturday to mark the anniversary. Long after they left, the widow of Daniel R. Boyett, one of nine bikers who were killed, sat on a bench recalling her husband, who would have turned 45 this month.

Mr. Boyett was a member of the Cossacks, but his widow, Nina Boyett, said he was not looking for trouble. Mr. Boyett, who owned a roadside-service business here, had made plans to be at his nephew’s fourth birthday party later that day.
