CASA GRANDE, Ariz. (AP) -- Authorities have released the names of two other people who died in a 19-vehicle pileup on Interstate 10 north of Picacho Peak during a dust storm.
Arizona Department of Public Safety officials say the other victims were 46-year-old Lenny Lubers of Phoenix and 51-year-old David D. Bechtel of Milton, Iowa.
They announced hours after Tuesday's noon crash that 76-year-old Gordon Lee Smith, of Mead, Wash., had died in the chain-reaction crash that also injured 12 other people.
DPS says the injuries ranged from minor to life-threatening and Smith's wife was among the injured.
They say 11 of the 19 vehicles involved were large commercial vehicles.
Investigators say a stream of thick, blowing dust crossing I-10 led to the crash after visibility for motorists was reduced to zero.
