Several dozen people rallying in protest of a fatal shooting by Los Angeles police on Skid Row have begun a march to police headquarters.

The rally Tuesday morning included a moment of silence, and participant Patrisse Cullors declared the shooting site "sacred ground."

Police officers are directing traffic as the group heads toward the downtown police administration building where a there is a scheduled meeting of the city Police Commission, a panel of civilians who oversee the Police Department.

The unidentified homeless man was shot on Sunday near a downtown homeless shelter.

A memorial sprung up Monday where the shooting occurred. White roses were placed over a tent, blankets and clothing belonging to the man known as "Africa."

The shooting was captured on video, but exactly what happened remains unclear.
