PHOENIX (AP) – An SUV careened off a Phoenix freeway overpass, landed on a median and burst into flames, killing a woman and her four young sons, authorities said Thursday.

Arizona Department of Public Safety officials identified the woman as 39-year-old Durjuana Miller of Phoenix, who was the driver. The names of the four boys who died weren’t immediately released, but the DPS said they were ages 8, 6, 3 and 3 months.

The SUV failed to slow enough at the top of an Interstate 10 off-ramp to make a turn Wednesday night, according to the DPS.

“There was skid (mark) on the ground, so the driver tried to slow down but was not able to negotiate that corner,” DPS Capt. Damon Cecil said.

After hitting a barrier, the vehicle flew end over end and then dropped 50 feet down to the freeway’s dirt median, where it landed on its wheels and burst into flames.

“It was fully engulfed,” Cecil said. “None of the occupants were able to get out.”

DPS officials said investigators were trying to determine the cause of the crash.
