OAKLAND -- Four reputed gang members, including two brothers, have been convicted of their roles last July in a Hayward carjacking and a subsequent vehicle pursuit in Oakland where a California Highway Patrol officer was shot at and had his car rammed, officials said Thursday.

The announcement of plea bargains in the case, reached last Friday, was made during a news conference at Oakland police headquarters, by police prosecutors and CHP commanders.

Joseph Gonzalez, 19, will be sentenced later this month to 27 years in prison after being convicted of assault on a peace officer with a semi-automatic firearm and gang and other enhancements.

His brother, David Gonzalez, 24, who was convicted of carjacking, will be sentenced to three years June 28 and Samiuela Sina, 19, who was convicted of carjacking, will get an 8-year term. Kenyon Thomas, now 18, who was prosecuted as an adult, will receive five years probation for robbery on Aug. 30.

The four Oakland residents admitted their involvement said Deputy District Attorney Elgin Lowe, who prosecuted the case.

Interim Oakland Police Chief Sean Whent called the four "significant violent criminals who want to do harm to people who protect our community."

Paul Fontana, a sector chief with the CHP's Golden Gate Division, said the arrests and convictions mean "four dangerous criminals are off the street so they are not able to target innocent people."


Authorities said the four drove a Dodge van to Hayward where an Acura was carjacked at gunpoint the night of July 21 and then returned to Oakland in the two vehicles.

At 8:30 p.m. on July 21, CHP Officer S. Deise attempted to stop the van containing David Gonzalez and Sina for a seat belt violation near the 800 block of 50th Avenue, not being aware of the earlier carjacking. Deise's first name was not released by police.

The van sped off with the officer in pursuit. During the chase Deise's car was rammed by the Acura driven by Joseph Gonzalez, with Thomas as a passenger. Gonzalez also fired the shots at the officer, who was not injured and has returned to duty. Fontana said the gunfire shattered the rear window of the patrol car and an emergency light bar inside stopped a bullet "that looked to be a straight shot at our officer."

The van and car eventually stopped and the suspects fled on foot. David Gonzalez and Sina were arrested that night.

Joseph Gonzalez was arrested two days later in Oakland and Thomas was arrested Sept. 5 in East Palo Alto.
