A van collided with a bus carrying Dallas Cowboys staffers but no players on an Arizona highway, leaving four dead in the van, authorities said. The bus occupants emerged uninjured from Sunday's crash, Arizona Department of Public Safety spokesman Quentin Mehr said. ''All on the bus came through OK with some bumps and bruises,'' Cowboys spokesman Rich Dalrymple (DAHL'-rimp-ul) said in an email.
