DEMING, NM - Authorities have released the identities of six Arizonans killed last month in a fiery multi-vehicle crash along Interstate 10 in southwestern New Mexico .
They say the name of the seventh person who died still hasn't been confirmed.
New Mexico State Police say the eight-vehicle crash on May 22 involved at least three tractor-trailers and three passenger cars in Hidalgo County, several miles from the Arizona border.
A sudden dust storm likely triggered the chain-reaction collisions.
Police say 54-year-old Hyon Suk Head of Tucson was killed in one of the cars while 43-year-old Larissa Wallace and 9-year-old Wyatt Wallace -- both of Circle City -- both died in a minivan.
Three Tucson residents in a car also were killed -- 40-year-old Joseph Guttuso, 38-year-old Marine Guttuso and 40-year-old Morgan Earle Cole.
