LOS ANGELES -

A coroner's report says the Porsche carrying "Fast & Furious" star Paul Walker may have been going 100 mph or more before it crashed, killing both Walker and the driver.
    
The report released Friday by the Los Angeles County coroner's office says that Roger Rodas, Walker's friend and financial adviser, was driving the 2005 Porsche Carrera GT at an unsafe speed, estimated by witnesses to be 100 mph or more.
    
The report also says no alcohol or drugs were detected in the system of either man on the day of the fiery one-car crash.
    
It says the Nov. 30 deaths have been ruled accidents and were due to combined traumatic and thermal injuries.
    
Investigators found no mechanical problems with the Porsche or problems with the roadway.
