A Bob Lee video showed the Cash App co-founder in front of a high-end apartment complex when he was attacked Tuesday.

The two-minute video shows how he struggled and desperately asked for help before falling to the ground and getting on his knees and elbows, according to the Daily Mail.

When he was attacked, Lee, 43, was strolling through the progressive city's posh Rincon Hill area early on Tuesday morning.

The dying tech tycoon repeatedly and desperately tried to flag down passing automobiles, only to watch in despair as they sped away, as shown in the Bob Lee video.

A terrible murder in the district of former House Speaker Nancy Pelosi, a staunch Democrat, has sparked concern over public safety and rising homelessness in San Francisco.

Lee, a former San Franciscan who left the city due to rising crime, can be seen in the first scene of the disturbing footage, wobbling along Main Street in the aftermath of the stabbing.

A chilling 911 call reveals that the Cash App co-founder was begging for aid shortly after being stabbed before collapsing and dying, per NY Post.

"A male is screaming 'help,' saying 'someone stabbed me,'" a dispatcher can be heard saying in the 911 call. "Advised he is bleeding out. He's outside on the street."

Lee, holding his phone in one hand, tried to call the building's intercom before passing out, as seen on surveillance tape.

They also assure the citizens of San Francisco that their department is fully staffed and prepared to respond to any emergency.
