SAN MATEO, Calif. The mother of one of the survivors of a limousine fire that killed five women when it burst into flames as it traveled over the San Mateo bridge says the women were heading to a bachelorette party.
Rosita Guardiano told the San Francisco Chronicle that the bride-to-be was one of the people killed in the Saturday night fire on the San Mateo Hayward Bridge. She says the woman was to be married next month.
Guardiano says her daughter -- 42-year-old Mary Grace Guardiano of Alameda -- is in intensive care, where she's being treated for smoke inhalation. Three other woman also suffered smoke inhalation and burns.
In addition to Ms. Guardiano, CBS affiliate KPIX in San Francisco has learned the identity of two other survors -- Jasmine Desguia from San Jose and Amalia Loyola from San Leandro are both in critical condition at Santa Clara Valley Medical Center.
The limo was carrying nine passengers -- all women -- when it burst into flames around 10 p.m. Saturday. Authorities say the five women who died were trapped inside, while four others and the driver, managed to escape.
San Mateo County Supervising Deputy Coroner Michelle Rippy says autopsies are being conducted to determine the exact causes of death of the five who were not able to make it out of the burning limo.
All five were pronounced dead at the scene.
The four women who escaped were taken to area hospitals where they were being treated for smoke inhalation and burns.
The limo was going west on the bridge at about 10 p.m. when smoke began pouring out of the rear passenger area, the California Highway Patrol said Sunday. The driver managed to stop the car and he and those in the front scrambled to safety. But the fire evidently spread so quickly that the rest of the occupants were unable to get out in time.
Emergency crews extinguished the blaze before it engulfed the entire vehicle, but the rear one-third of the white, 1999 Lincoln Town Car was left a charred ruin.
The dead women were all in their 30s and 40s, the CHP said.
The women were apparently going from Alameda to Foster City. The survivors, also in their 30s and 40s, were taken to Stanford Medical Center and to Valley Medical Center in San Jose for treatment of smoke inhalation and burn injuries.
The driver was not injured. His name has not been released.
