A May 23 trial date was set Tuesday for two men who are charged with illegally possessing firearms during an April 2010 raid on a motorcycle gang clubhouse in which a man was fatally shot by deputies.

Also Tuesday, U.S. District Judge Gregory Frizzell found one of the defendants, Scott Lee Sollars, mentally competent, clearing the way for a trial to be held next month in the case against him and co-defendant Albert Dee Ahlfinger.

Sollars, 55, and Ahlfinger, 50, were charged last spring with firearm and ammunition possession despite having felony records.

The charges stem from an April 9, 2010, raid by law enforcement officers at a building in the 1800 block of North Kingston Place, during which Russell Doza was fatally shot by Tulsa County sheriff's deputies. Doza had picked up a pistol and turned toward them, the deputies said.

The raid was conducted after an informant alleged that drugs were being sold at the building, which was then the "Rogues Outlaw Motorcycle Gang Clubhouse," according to an FBI affidavit.

In the building, firearms were "accessible to all subjects in the house," arrest reports state.

The indictment says Ahlfinger's record includes a 1996 conviction for possession of a controlled substance and a 2008 stolen-property conviction, both in Tulsa County. It says Sollars has convictions in Kentucky, Florida and Oklahoma for crimes such as burglary, auto theft, possession of a controlled drug and illegal gun possession.

On Sept. 9, Frizzell ordered Sollars to undergo a mental examination to determine his mental competency. The report has not been made public, but Frizzell said it indicates that Sollars' "status has improved."
