Dust storm leads to deadly wreck
CASA GRANDE, Ariz. (AP) -- A stream of thick, blowing dust crossing an Arizona highway led to a chain-reaction crash that killed three people in an area where gusting winds often stir up towering clouds of dirt that can reduce visibility to zero.
At least 12 other people were injured Tuesday in the 19-vehicle pileup on Interstate 10 between Phoenix and Tucson.
Crews brought in portable lights as they worked past sunset to pry apart the 10 commercial vehicles, seven passenger cars, one tanker and one recreational vehicle that were involved, Arizona Department of Public Safety officials said.
