4 people killed in fiery crash between SUV, big rig on LA freeway

LOS ANGELES -- Four people died in a fiery crash between an SUV and a big rig on Interstate 5 in Santa Clarita on Thursday evening, authorities said.

The crash took place just before 7:30 p.m. on the northbound I-5 at Calgrove Boulevard, just north of the interchange with the Antelope Valley Freeway, according to the California Highway Patrol.

Although Los Angeles County fire officials initially reported two people were killed, CHP Officer Patrick Kimball later said four people had died.

All four victims were believed to be occupants of the SUV, KTLA reported.

Witnesses initially reported the SUV was speeding at more than 100 mph before it slammed into the back of the big rig, CHP logs show.

First responders arrived to find the SUV stuck beneath the truck and engulfed in flames.

Aerial video of the scene showed the truck was carrying a load a lumber.

Officials shut down all but one lane of the northbound I-5 as they investigated the scene and cleared the wreckage, and traffic could be seen backed up to state Route 210.

Caltrans estimated that the roadway would fully reopen around 1:30 a.m.
