Calls for mistrials and testimony about the moments before shots being fired filled a South Dakota court room and wrapped up the first week in trial allegedly founded in motorcycle club rivalries.

John Midmore of Valparaiso, Ind., and Chad Wilson of Lynnwood, Wash., both members on the Hells Angels motorcycle club are charged with attempted murder for injuring five Outlaws Motorcycle Club members in a 2006 gunfight at Custer State Park.

On Thursday the judge handling trial refused to declare a mistrial after contradicting testimony from several prosecution witnesses. Motorcyclists who were at the scene said they saw a man later identified as one of the defendants fire the first shot toward the Outlaws, one of whom returned fire.

But during cross-examination, a defense lawyer challenged some of the statements, including one man's testimony that the second defendant got out of the truck and shot people who already had been hit.

Two people testified Friday at the Sioux Falls trial of two Hells Angels bikers that a pickup pulled out before they heard gunshots.
Michael Cain and Michelle Lewis said the truck, identified as Wilson's, cut them off as they turned into a parking lot. Several Outlaws had been shot, then they heard gunshots and a couple of Outlaws chased after the truck and banged on it. However, under cross examination Lewis acknowledged she didn't see who started the gunfight.

The trial continues next week.
