LOS ANGELES — Security video of a man driving into a crowd at a Los Angeles boardwalk opens with hundreds of people walking lazily or sitting at cafes before a black car suddenly appears and sends them scrambling wildly.

Restaurant manager Dennis Walker showed The Associated Press the seven-minute video of the Saturday melee that killed one person and injured 11.

It shows a young man parking the car next to the boardwalk. Minutes later he gets out wearing a baseball cap, gray shirt and white pants as he walks between the boardwalk and car for several minutes.

He then gets in and the car rapidly accelerates, screeching across a sidewalk to reach the promenade. The vehicle runs down sidewalk vendors and their booths and hits other people and objects as drives out of sight.
