New footage has been released of the moments after Bob Lee, Cash App founder and former chief technology officer of Square, was stabbed in San Francisco.

The newly released video was obtained by the Daily Mail, and it shows Lee collapsing in front of a business that was closed. He appeared to call someone on the phone, and it was reported that he was dialing 911 while also trying to flag down a car for help. According to reports, Lee allegedly told the 911 operator, “Help. Someone stabbed me.”

Lee could be seen falling several times and approaching another car, which sped away after Lee lifted his shirt to show his stab wounds. Police later arrived at the scene, where Lee was pronounced dead. A 4-inch kitchen knife was recovered from the scene, but police have yet to make any arrests.
