Reputed gang member who allegedly held open the sliding door of a van so fellow gang members could gun down a rival was found guilty today of first-degree murder.

 Ruben Hernandez, 28, who already is serving a lengthy sentence for another gang-related homicide, was found guilty of the 2005 slaying of Michael Moore, 30, of Aurora, and the attempted murder of Moore’s passenger, who was wounded in the shooting. Moore was killed Nov. 28, 2005, near the intersection of Galena and East boulevards in Aurora, when the van pulled alongside his car and someone inside opened fire, according to authorities. Hernandez did not shoot, but his actions made him accountable in the slaying, said Kane County Judge Allen Anderson, who presided over Hernandez’s bench trial. “The defendant was present and involved,” the judge said. Witnesses testified at the trial, which took place May 1-3, that Moore’s passenger, a reputed gang member, had gotten into a verbal altercation three days before the shooting with members of Hernandez’s gang. The alleged shooter is awaiting trial. Hernandez’s sentencing was set for July 2, but the outcome is not in doubt – he will automatically receive a life sentence since it is his second conviction on a homicide. He is currently serving a 40-year sentence for beating a man to death in anther gang-related slaying.
