Dateline NBC “Under the Bay Bridge” March 20 2026

Dateline NBC returns Friday night with a high-profile case that captured national attention. Under the Bay Bridge airs March 20, 2026, at 9/8c, with correspondent Josh Mankiewicz reporting on the shocking killing of tech executive Bob Lee in San Francisco.

Lee, known for his work in the tech industry, was fatally stabbed near the Bay Bridge in April 2023. The crime stunned both Silicon Valley and the wider public, raising urgent questions about safety, motive, and what really happened in the final hours of his life. Early reports suggested a random attack, but as investigators dug deeper, the case quickly became far more complicated.

The episode explores the twists that followed, including conflicting accounts, shifting theories, and the eventual identification of a suspect known to Lee. Detectives worked through digital evidence, surveillance footage, and witness statements to piece together a timeline of events that did not initially make sense. What emerged was a story that challenged early assumptions and revealed a more personal connection at the center of the case.

Through interviews and detailed reporting, Dateline examines how the investigation unfolded and why the truth proved difficult to pin down. Under the Bay Bridge offers a closer look at a case that blurred the line between public perception and reality, leaving many to question what really happened that night in San Francisco.
