(Chandler, AZ) -- Two people are dead following a crash on westbound I-10 that has shut down the interstate from Riggs Road to Loop 202. The Department of Public Safety says a semi crossed over the median, plowed into three vehicles, then flipped over and caught fire. The driver of the commercial truck was seriously injured, two adults and two children were hurt and two people were killed. There's no word on how long that stretch of I-10 will remain closed.
