RENO, Nev. (AP) - The former Reno pawnshop owner accused of murdering his estranged wife and shooting the judge handling their divorce has made his first appearance in court in a matter indirectly related to the charges against him. Darren Mack appeared on Thursday with his attorney, who claims the money in Mack's retirement account is not part of his wife's estate and can be used for his defense. But an attorney for Charla Mack's mother argued all funds should be off limits and Mack should not be allowed to use his slain wife's money to defend himself against murder charges. Probate Commissioner Lynne Simons ordered the funds frozen for another 30 days while lawyers file arguments on whether the pension funds are a federal matter. Mack, wearing a red jail jumpsuit and shackled at his wrists and ankles, watched attentively during the hearing and whispered to his attorney often.
