OAKLAND — Neighbors of the former NASA scientist who was killed near his home are rattled by the fatal shooting that took place in the typically quiet residential neighborhood Sunday morning.

Brian Bole, 30, who worked in the health care industry, was fatally shot not far from his home about 12:15 a.m. Sunday on the 3000 block of Richmond Boulevard. He died at the scene.

Jadene Lim and her husband Darry Louie were watching TV when they heard the gunshot come from across the street, she said. The couple said they have heard gunshots several times in their 40 years of living in the neighborhood.

” … But this one here, everyone heard the shot,” Lim said.

A neighbor who resides two doors down saw Bole’s body lying near a gravel parking lot and called police, she said. Another neighbor was smoking a cigarette on the porch when the shooting occurred.

None of the neighbors have reported seeing the suspect, though, she said.

“Nobody saw anyone run away or anything,” Lim said.

Oakland police are following up leads and going through video footage Thursday, Officer Johnna Watson said.

“We want to look for any evidence that could move this case forward to identify who is responsible for this crime,” she said.

It is not known whether Bole was randomly shot or targeted, and the department’s homicide unit is not releasing additional information, Watson said.

Since the shooting, Lim said neighbors are “banding together” to raise awareness and communicate about crime and exchange information. Some residents have decided to get surveillance systems installed on their properties.

“We’re all planning to put them in just to make it less where someone wants to do anything like that,” Lim said. “It’s dark because of the trees and stuff, but everyone feels safe so they just walk around feeling safe.”

Lim never met Bole, but she has met his roommates and friends who stopped at the makeshift memorial where he was found, she said. Bole’s friends appear to be “the techie types with good jobs and advanced degrees.”

The neighborhood is mostly populated by retired couples and 30-somethings, Lim said. Although residents are shaken by the killing, none of her neighbors are thinking about moving.

“It’s just that nobody was expecting that, so everyone is still in a funk,” Lim said.

Bole’s family members could not be reached for comment.

Police are looking for possible witnesses and anyone in the area who might have surveillance video.

Violent crime is extremely rare in the area, which is primarily residential and home to Oak Glen Park.

Police and Crime Stoppers of Oakland are offering up to $10,000 in reward money for information leading to the arrest of the killer. Anyone with information may call police at 510-238-3821 or Crime Stoppers at 510-777-8572.
