The Arizona Highway Patrol is conducting an extensive and detailed investigation into a collision that took the lives of four people on Interstate 10 west of Tonopah Saturday afternoon.
According to Arizona Highway Patrol, investigators believe there was an initial collision, followed by one or more secondary collisions, which resulted in additional injuries and deaths.
Troopers are investigating whether blowing dust was a significant factor in the collisions by potentially causing reduced visibility.
At this time, troopers believe the collision involved six commercial motor vehicles, four passenger vehicles, a van, and a recreational vehicle towing a trailer.
There are four confirmed fatalities, two people in critical condition who are receiving life-saving treatment, one person admitted for care and precautionary treatment, and five more people who were treated and released. These individuals were transported to numerous hospitals in the Valley area.
State troopers are still working to contact all the families of those involved and will not be releasing names or identification at this time.
The eastbound travel lanes of Interstate 10 were reopened for traffic at approximately 3:10 a.m. on Sunday, March 2, 2025.
