The stretch of interstate from Lordsburg to Willcox, Arizona, was closed for hours following the crash, and reopened Tuesday morning.
State police say sudden high winds created limited visibility from blowing dust, causing 18 commercial trucks and seven passenger cars to crash on the westbound lanes of I-10.
The interstate at Lordsburg has seen several closures this year because of blowing dust and low visibility. The dust comes from vacant desert land in the largely rural area.
In February, two women were killed when their car got sandwiched between two semi-trucks in a crash caused by a dust storm.
The dead Monday were identified as 77-year-old Jose Manuel Clemente and 38-year-old Maurella Clemente Munoz of El Paso; 30-year-old Jose Elias Caraveo-Serrano and 29-year-old Susana Caraveo of Phoenix, along with their 9-month-old daughter; and 47-year-old Josefina Silva of Escondido, California.
