SAN FRANCISCO (KGO) -- One driver is dead following a terrible four car crash Thursday on one of San Francisco's busiest streets.

Lombard Street was shut down for hours following the crash that left wreckage behind at the intersection of Lombard and Divisadero. We're learning that a stuck accelerator pedal might be to blame.
Walgreens pharmacist Cynthia Thai won't forget the sound of cars colliding at the intersection of Lombard and Divisadero streets. "I just heard a really loud bang," she said. "A lot of people scrambled to the front to see what was going on, it's crazy, I couldn't imagine how many got hurt."
A white Prius was reduced to twisted metal after police say it was hit broadside by a maroon ford SUV. Paramedics tried to save the life of the man inside.
"They pried the door off and gave him CPR for 15 minutes until ambulances showed up," said John Headley, who witnessed the crash.
The man did not survive and several other drivers were sent to the hospital.
Police say the driver of the maroon SUV was going about 60 miles per hour down Divisadero Street possibly due to a stuck accelerator pedal, which caused the SUV to run a red light at Lombard.
"The car was coming down, totally turned, knocking the car 30 feet and kept going," said Headely. "They were a pretty elderly couple."
Headely works at a nearby pet store. "That's an intersection where I've seen three accidents before while I was here," he added.
The two streets were closed for hours, creating traffic gridlock on Lombard and many other side streets through the Marina District.
An investigation into the crash is underway.
