Investigators found no signs of arson or an accelerant after their initial examination of six cars destroyed by fire while parked in the San Francisco International Airport’s long-term parking lot on Thursday, according to the San Mateo County Sheriff’s Office.
The fire was reported at about 12:30 a.m. after a shuttle bus driver noticed a car on fire in the long-term parking lot near the United Airlines Maintenance Base.
A parking lot security guard was the first person on the scene and tried unsuccessfully to put the fire out.
The fire totaled six cars, and one other car sustained some damage, according to the sheriff’s office.
The sheriff’s office towed the first vehicle that caught on fire, which had been in the long-term parking lot since July 13, for further inspection. The vehicle’s owner has been notified of the fire but is currently out of the country.
Surveillance cameras for the lot are trained on the entrance and exit points, but airport spokesman Mike McCarron said there are no cameras in the area where the fires burned.
He said the parking lot is still fully operational.
The blaze is still under investigation. Anyone who has any information about the incident can call (650) 821-6205.
