A man stumbles into the view of a surveillance camera aimed outward through the glass front door of a building lobby.

He reaches out, placing his left hand against the doorframe before collapsing on to the sidewalk outside.

The view changes to another camera, this one outside, facing the other way. The man gets up, holding a phone in one hand with the other pressed tight against his ribs, dripping blood on the sidewalk before walking off.

The man was Bob Lee, a 43-year-old tech innovator who founded Cash App and was an executive at both Square and MobileCoin before his stabbing death early Tuesday morning.

It is unclear if the video is the same one described by a San Francisco Standard article earlier this week, but it appears to show the same sequence of events.

Police arrived within minutes and rushed him to the hospital, where he died.

Police have not publicly identified a suspect, although they have likely obtained additional surveillance video in the area.

In a statement, San Francisco Police Chief Bill Scott said that the department would not be commenting on evidence in the case due to the active investigation. However, he said that investigators were working "tirelessly" to find the killer.
