UNION CITY -- Authorities have released the identity of a Sunnyvale man found dead Saturday after a bank robbery led to a car chase that ended with exchanges of gunfire between an officer and the man, police said.

Francis Buhay, 36, was found shot in the head in the backyard of a home on the 2700 block of Dowe Avenue, Lt. Ben Horner said. Authorities believe Buhay's fatal wound was self-inflicted, Horner said.

In 1999, Buhay was convicted in a federal court for robbery, police said.

Anthony Pabros, a Fremont man whom authorities say drove the getaway car after Buhay robbed a Union City bank, is expected to enter a plea Friday at the Fremont Hall of Justice.

Pabros, the owner of Kingdom clothing store on Smith Street in Union City, is being charged with four counts of robbery and one count of shooting at a police officer, deputy district attorney Angela Backers said.

Pabros, 36, of Fremont, was taken into custody Wednesday after a court appearance where he had his bail revoked.

Backers told Alameda County Superior Court Judge Dennis Hayashi that Pabros was a "risk to the public" and "a danger to society."

"We filed a motion to set his bail at $1 million," Backers said. "But now his bail is zero and he'll remain in custody until he can prove that whatever bail money he can post is from a legitimate source."

A family member loudly wept in the courtroom when Pabros was handcuffed and taken away.

Pabros' attorney, Douglas Rappaport, did not return a phone message left Thursday.

The incident Saturday started around 12:45 p.m. when police responded to a 911 call reporting an armed robbery at Bank of the West at 33301 Alvarado Niles Road.

When the robber, identified by police as Buhay, left the bank and hopped in a car they say was driven by Pabros, officers pursued the vehicle for about a half-mile.

The driver pulled over in a residential intersection and Pabros was arrested. But Buhay ran away while firing a handgun at officers, police said.

Officers returned fire as Buhay fled into the backyard of a nearby home, Horner said.

Authorities eventually found Buhay dead in the backyard with a weapon near his body, police said.
