June 10 (UPI) -- A semi hauling a tanker burst into flames overnight in a multiple-vehicle collision that killed four and injured nine.
The commercial semi hauling a trailer filled with milk failed to slow upon hitting traffic in the area of 52nd and Van Buren streets while traveling eastbound on Red Mountain Loop 202 around 10:09 p.m. and collided with seven passenger vehicles, according to the Arizona Department of Public Safety. The tanker trailer broke away from the truck, and went over the concrete barrier median wall into westbound traffic.
Arizona DPS spokesperson Raul Garcia later told AZFamily the tanker was leaking both milk and diesel fuel, according to the Phoenix Fire Department, and at one point ended up in flames. Another vehicle involved in the crash had caught fire as well.
Four people died as a result of the crash, according to DPS, and several others were injured.
Fire officials said paramedics took nine to nearby hospitals, six of whom ranged in age from 22-45 and had critical injuries. Another three had non-life threatening injuries, with a 6-year-old girl among them, AZFamily reported.
Detectives and troopers are working together on the investigation, and have ruled out impairment, according to DPS.
