Two men have been arrested and charged with open murder, robbery and conspiracy to commit robbery in the death of 15-year-old Marcos Arenas in Las Vegas last week. Jacob Dismont, 18, and Michael Solid, 21, were charged Saturday over the incident. According to police, the two attempted to steal an iPad away from the youth but he refused to let go of it, resulting in his being dragged and run over by the two men.
