Golden Gate Transit bus driver Ersie “Chuck” Everett, a 58-year-old San Leandro man, has been identified as the second victim of a fatal shooting at the Richmond-San Rafael Bridge toll plaza Tuesday evening.Everett was killed along with 51-year-old Richmond resident Deborah Ross shortly before 6 p.m. Tuesday, allegedly by Ross’ boyfriend, 46-year-old Nathaniel Burris.Ross was working at the bridge as a toll collector when the shooting happened. She had worked for Caltrans for eight years. Burris allegedly shot Everett as he sat in a car in the toll plaza parking lot, police said. After the shooting, Burris fled in a white Ford van bearing the words “Western Eagle Shuttle,” prompting a statewide search and airport alert.Western Eagle Shuttle is a San Rafael-based airport transportation company, according to its Web site, and French said it’s likely Burris worked there.A California Highway Patrol officer arrested Burris on Interstate Highway 80 near the Sierra mountain community of Baxter in Placer County just after 3 a.m. today, French said.He and Ross had been in a dating relationship and lived together in the 400 block of Second Street in Richmond, according to French.Police did not know whether the couple had a history of domestic violence. French confirmed today that police had been called to their home Sunday, but said she didn’t know what the call was for.Investigators have not confirmed the nature of the relationship between Ross and Everett but believe they knew each other, French said.She said police would likely bring Burris back to Contra Costa County on Friday. Investigators have until Friday to take the case to the district attorney’s office, she said.Autopsies were being conducted on Ross and Everett’s bodies this morning, a Contra Costa County deputy coroner said.Flags at the state Capitol in Sacramento are being flown at half-staff today in Ross’s honor, according to Schwarzenegger’s office.Golden Gate Transit was holding a news conference late this morning to remember Everett, who was first hired by the agency in 1990, according to Mary Currie, spokeswoman for the Golden Gate Bridge, Highway and Transportation District.
