CASA GRANDE, Ariz.(AP) Three people were killed and at least 12 injured after a dust storm led to multiple crashes Tuesday on Interstate 10 between Phoenix and Tucson, authorities said.
Arizona Department of Public Safety(DPS) officials identified one of those killed as George Lee Smith, 76, of Mead, Wash.
They said Smith's wife was injured, but her condition wasn't immediately disclosed.
