Washoe County prosecutors have decided to retry an ex-motorcycle gang member on murder charges after the state Supreme Court overturned his conviction in a 2011 shootout with rival gang leaders at a northern Nevada casino.  Washoe District Judge Connie Steinheimer has scheduled a hearing June 8 to consider the motion for a new trial for Ernesto Gonzalez and set a date for the proceedings. Michelle Bays, spokeswoman for the district attorney’s office, confirmed assistants to District Attorney Chris Hicks will argue for the retrial. The Supreme Court overturned Gonzalez’ conviction in December partly because of faulty instructions provided to the jury that found the former Vagos leader guilty of killing Jeffrey “Jethro” Pettigrew, ex-president of the Hells Angels in San Jose, California.
