OAKLAND  (AP) — Some security cameras aboard San Francisco Bay Area commuter trains are fake and do not record the activity of passengers, a transit agency acknowledged after being pressed on whether there is footage of a weekend killing on a train.

Bay Area Rapid Transit Director Gail Murray told the Oakland Tribune in a story Friday (http://bayareane.ws/1n5KwL4) that some cameras are decoys and others record images. The story was first reported by the San Francisco Chronicle.

The transit agency has not released any footage of the shooting and refused to say if the killing Saturday was captured by security cameras.

The Alameda County Coroner’s Office on Friday identified the man as Carlos Misael Funez-Romero, 19, of Antioch, California.

He was shot as a San Francisco-bound train rolled into the West Oakland station. No arrests have been made.

The transit agency also has surveillance cameras on station platforms and at fare boxes. Police have distributed images of the suspected gunman taken by one of those cameras.

Cameras were installed in train cars beginning in 1988 as a way to stop vandals.

The newspaper looked at 140 camera lights in 35 BART cars on six trains moving between San Francisco and Oakland on Thursday. Only 24 of the cameras displayed a green light. The remaining 116 cameras displayed either a red light or no light at all.

Attorney Ernesto Castillo, who has defended people charged with BART crimes, said the transit agency has consistently failed to produce footage of purported crimes reported on trains.

“In my experience, every single case I’ve had that occurred on BART there’s never been footage,” Castillo said. “There is no reason BART shouldn’t have cameras functioning on every train.”
