Investigators seek answers in deadly limo fire Updated at 5:20 p.m. He helped four of the surviving women escape through the partition. One of the women ran around to the passenger door on the back side of the limo, but by then it was engulfed in flames. "When she opened that back door, I knew it wasn't a good scene," Brown said. I figured with all that fire that they were gone, man. There were just so many flames. Within maybe 90 seconds, the car was fully engulfed. Investigators have done preliminary interviews with survivors and the driver but need to re-interview them, Maskarich said. It will take a few weeks for investigators to piece together "some semblance of answers for the tragic events that just occurred," he said. Debris or any other objects on the roadway do not appear to have been a factor, added Maskarich. San Mateo County Coroner Robert Foucrault said they doubted that the blaze involved criminal activity. His office planned to begin autopsies later Monday. "My guess would be they were trying to get away from the fire and use that window opening as an escape route," said Foucrault. Brown said he wishes he could have done more. "It's something you never imagine will happen," he told the Chronicle. It's a limousine ride. It's supposed to be a joyous thing. Brown said he is an experienced commercial driver who has operated airport shuttles and trucks. He started driving for Limo Stop two months earlier and had put in about six shifts behind the wheel of the Town Car that caught fire, he said.
