Oakland police say six people have been shot in the city's downtown area and that a teenage girl is in critical condition.

The Oakland Police Department says a 16-year-old girl is listed in grave condition and that the other victims in Tuesday evening's shooting are in stable condition.

Police say the victims range in age from mid-teens to early twenties.

The department says the shooting happened during a vigil two blocks away for someone drowned last year in Salinas, California.

It's unclear if the shooting is connected to the memorial gathering.

The San Francisco Chronicle reports the broad-daylight shooting sent people ducking for cover.

Mason Stone tells the newspaper people were running "every which way."
