CONCORD — Nearly 18 months after a fatal shooting in one of its train cars, BART workers finished installing the final working surveillance camera in its fleet Wednesday, officials said.

The Jan. 9, 2016 shooting exposed the fact that approximately 70 percent of BART’s on-board cameras — including the one where the shooting occurred — were fakes, as police scrambled to find images of the suspect.

BART shooting: Man fatally shot on train identified as Antioch resident Carlos Misael Funez-Romero, 19, was shot while in a train at West Oakland station. The packed BART train had slowed to stop around 7:40 p.m. when the gunman shot Funez-Romero, who was seated near the doors of the train car. The sound of gunfire reverberated through the other cars in the train and sent some passengers fleeing through open car doors, while others rushed to aid the bleeding victim.

The bystanders attempted to provide emergency medical care, as some shielded his body from view. Ultimately, however, Funez-Romero died at the scene.

The incident sparked a public outcry after it was discovered the cameras on Funez-Romero’s train were decoys — installed in the late ’90s and early 2000’s as a way to deter vandalism — and hadn’t captured the shooting or the suspect. The agency was able to get surveillance footage of the suspect from cameras on the station’s platform, but to date, no arrests have been made in the case, said BART police Lt. Terence McCarty.

BART officials quickly promised to replace the decoys with working cameras, but it wasn’t until August, seven months after the fatal shooting, that BART’s governing board approved the purchase of operational cameras, along with related hardware, for the roughly 470 train cars lacking working cameras, in a $1.42 million overhaul of its surveillance system.

The final installment Wednesday marks the completion of that effort and makes good on a promise to the public to replace the cameras by July 1 this year.

McCarty said it isn’t clear that working surveillance cameras on the train car where Funez-Romero was shot would have aided investigators in identifying the suspected assailant, since the agency already collected the man’s image from cameras inside the stations and on the platform.

“I can’t recall a case (of violent crime) where we were frustrated because we had a lack of train car cameras,” McCarty said. “We’ve been pretty successful in the past regardless of not having them on the train cars.”

McCarty did say that have more cameras installed has helped officers identify suspects in other crimes, McCarty said. In April, a group of 40 to 60 minors jumped the turnstiles at the Coliseum station and boarded a train, with some among the group robbing and beating patrons. McCarty said the agency received seven reports of robberies that evening. And, so far, he said the surveillance footage helped officers identify two of the suspects, who have since been arrested.

“We’re very hopeful this will be a deterrent and will make the system safer,” McCarty said.

The cameras need to be replaced every six to seven years. BART is in the process of replacing its current fleet of 669 train cars with 775 new ones. Those new cars all have working cameras already in place, and they will be phased in over the next several years, coinciding with the time it will take for the aging fleet to retire from service, officials said.
