A grand jury has been empaneled and is poised to consider the cases of 177 people arrested after the May shootout involving bikers and police in Waco.

The McLennan County district attorney subpoenaed two high-ranking members of the Confederation of Clubs and Independents, a coalition of motorcycle clubs that advocates biker safety, to provide information Wednesday about the confederation’s meeting that was to take place May 17 at a roadside restaurant.

Nine people died and 20 were injured during the shooting, which authorities say arose from an apparent confrontation between the Bandidos and the Cossacks motorcycle clubs.

None of the 177 people arrested and held for days or weeks on $1 million bonds has been charged. It remains unclear whose bullets struck those who died or were hurt.
