The crash happened on the 101 Freeway near Las Virgenes Road at 8:30 a.m. Saturday.
The California Highway Patrol said a new witness came forward Monday, saying a white SUV swerved and possibly caused the collision.
Moments after her car crashed, 27-year-old Gilani Taylor was on fire. She crawled from the wreckage as good Samaritans literally ran toward her to put out the flames. It's emotional to think about for her family.
"We know she will walk out of there, and we just want to say glory on to His name, because that's what she wants me to do," said Taylor's father. "We love her dearly."
Taylor suffers from burns on 95 percent of her body.
"Her chances of surviving are small at best. Children occasionally survive burns this size. In general, adults don't. She's a healthy 27-year-old, so I think we give her her shot and do the best we can and see what happens," said Dr. Warren Gardner of the LAC-USC Trauma Center.
Taylor is an aspiring singer-songwriter and was scheduled to perform in Ventura on Saturday night.
"She's going to come through this, you are going to see a miracle," said Taylor's husband, Rodney.
Taylor's 9-year-old daughter, Jayla, never made it out of the car.
"My daughter, the first thing she would ask is, 'Do you all have any books?' And you'd look around, everybody is partying, but my daughter, she's in the corner reading her book," said Rodney Taylor.
Officials are looking for a white SUV, but they do not have any sort of make or model description.
