HACKNEY. >> I'M ANDREA NAKANO. >>> YOU'VE LIKELY SEEN THE VIDEO ALL OVER SOCIAL MEDIA TODAY, A CAR FLYING OVER THE SANCHEZ STAIRCASE IN SAN FRANCISCO THROUGH THE BRANCHES OF TREES SMASHING INTO THE ROAD BELOW. >> THIS IS WHAT THE SCENE LOOKED LIKE TODAY, TREE LIMBS AND CRACKED CONCRETE LITTERING THE SIDEWALK AND THE ROAD RIGHT NEAR DOLORES PARK. INVESTIGATORS SAY THE CAR DROVE DOWN THE STREET, PLUMMETED OVER THE STAIRS AND LANDED UPSIDE DOWN ON 19th STREET. BY THE TIME POLICE ARRIVED, THE PEOPLE INSIDE THE CAR WERE GONE. >> BETTY YU SPOKE TO THE NEIGHBORS WHO SAY IT'S CLEAR TO THEM THAT THIS GROUP WAS IN A STOLEN CAR. >> Reporter: IT'S THE KIND OF CRASH YOU MIGHT SEE IN A HOLLYWOOD MOVIE. A CAR BARRELED THROUGH A GUARDRAIL ON A DEAD END STREET IN DOLORES HEIGHTS, FLEW DOWN AN EMBANKMENT, KNOCKED DOWN A TREE AND LANDED UPSIDE DOWN AT 19th AND SANCHEZ AROUND 7:20 SATURDAY. >> THERE IS A WOMAN PULLING OUT A GUY ALL BLOODY AND THE GUY HAD A FULL FACE MASK, ALL BLACK DRESSED IN BLACK. SHE WAS IN BLACK, RED HAIR, YELLING AT THEM "WE HAVE THREE MINUTES TILL THE COPS COME. HURRY UP." >> Reporter: SAN FRANCISCO POLICE SAID EVERYONE INSIDE THE CAR FLED THE SCENE. MIKE PEREZ RUSHED OVER TO HELP THE FIVE PEOPLE INSIDE. >> WE SAW WHAT WAS GOING ON. THERE WAS BOTTLES OF ALCOHOL POURING OUT OF THEIR CAR. THEY WERE ALL BLOODIED. YOU COULD TELL THEY WERE UP TO NO GOOD. THEY WERE VANDALS. YOU COULD TELL BY THE WAY THEY WERE DRESSED. THEY DIDN'T WANT OUR HELP. SHE SAID, "DON'T TOUCH ME." >> Reporter: THIS NEIGHBOR SPOKE TO A MAN WHO SAID HE'D JUST BEEN CARJACKED. >> THEY KICKED HIM OUT OF HIS CAR A COUPLE MINUTES BEFORE SOMEWHERE DOWN THE BLOCK. HE KIND OF FOUGHT THEM AND IN THE END THEY HIT HIM IN THE HEAD I THINK WITH A GUN. THAT'S WHAT HE SAID. HE SAID WHEN THEY WERE FIGHTING, HIS SHIRT GOT TORN AND I SAW THAT. >> Reporter: THIS DROP IS ESTIMATED TO BE AT LEAST 50 FEET. ONE WITNESS TOLD US THAT A POLICE OFFICER SAID THAT A GUN WAS ALSO FOUND AT THE SCENE. >> I THINK IT'S A GREAT EXAMPLE OF HOW THE LAWLESSNESS IN SAN FRANCISCO HAS REAL IMPACT ON THE ACTUAL CITIZENS AND NEIGHBORS WHO LIVE IN THE CITY AND SO I HOPE THIS IS LIKE A LITTLE BIT OF A WAKE-UP CALL TO OUR POLITICIANS THAT WE NEED TO PROSECUTE CRIMES, HAVE MORE POLICE OFFICERS PERFORM. >> Reporter: DAVID WAS READING A BEDTIME STORY TO HIS DAUGHTER WHEN HE HEARD THE COLLISION. >> LATER ON IN THE CAMERA I FOUND OUT THAT I PASSED DIRECTLY PASSED TWO OF THE PERPETRATORS OR TWO OF THE VICTIMS, WHATEVER YOU WANT TO CALL THEM. AS THEY CAME UP THE STEPS, I WENT DOWN THE STEPS, BUT IN THE CHAOS NO ONE REALLY NOTICED. >> Reporter: MICHAEL PAINTED THE MURAL ON THE STEPS TO BEAUTIFY THE NEIGHBORHOOD AND DETER GRAFFITI. >> VERY, VERY EASILY IT COULD HAVE BEEN ME. I STILL HAD PAINT ON MY HANDS FROM WHEN I PAINTED THIS. >> Reporter: LUCKILY NO PASSER-BY WAS INJURED. >> I'M SCARED. I LIVE LIKE A D COUP
