At approximately 1:34 p.m., on Friday, March 14, the Arizona Department of Public Safety responded to a multi-vehicle collision on westbound Interstate 40 near milepost 294 in Sun Valley.

According to the AZDPS, a commercial truck tractor and trailer rear-ended a Cadillac Escalade, causing a chain reaction that involved a Jeep Wrangler and another commercial truck tractor and trailer.

Tragically, five individuals lost their lives as a result of the crash. Two others sustained injuries, while one individual was unharmed. Those deceased include Jeet Vikram, 34, of Ozone Park, NY, Sarah Broyel-Case, 50, of Fort Collins, Colo., a 17-year-old Scottsdale boy, a 17-year-old girl from Fort Collins, Colo., and Samuel Case, 51, of Fort Collins, Colo., who passed away in the hospital on March 18.

This incident remains under investigation, and further details will be released as they become available.
