The fourth and final defendant in the Dewey Tucker murder case was sentenced Wednesday to six years and four months in prison for his participation in the mistaken identity, drive-by slaying of the Vallejo musician.

Christopher “Spider” Mancinas, 32, was acquitted of the Jan. 12, 2010 murder, and of conspiracy and shooting into an occupied vehicle, but he was convicted of participating in a criminal street gang.

He also was sentenced in Sonoma County Superior Court Wednesday to eight years in prison for an assault in 2006 and to seven years and eight months in prison for sales of methamphetamine in October 2010. His total prison term is 22 years, Deputy District Attorney Robert Waner said.

Mancinas was one of four Sureno gang members charged with Tucker’s murder.

Raul Vega, now 22, who shot Tucker, was convicted and sentenced to life in prison without parole and 25 years to life for the first-degree murder.

Javier Carreon-Lopez, now 23, pleaded no contest to being a member of a street gang and was sentenced to two years in prison.

Hector Barragan, now 32, also pleaded no contest to being an accessory and was sentenced to three years probation.

Tucker, 24, was killed while driving in his Nissan to band practice in the East Bay on westbound Interstate Highway 80 near the Carquinez Bridge.

Vega, Barragan, Mancinas and Carreon-Lopez drove to Vallejo to find a member of a rival sect within the Sureno gang who lived next door to Tucker, according to the testimony at Vega’s and Mancinas’ trials.

Vega and Javier Carreon-Lopez, 22, got into a Honda and pursued Tucker who they thought was the rival gang member. Carreon-Lopez pulled alongside Tucker’s Nissan and Vega shot Tucker in the head.

Mancinas testified at his trial that he and Barragan chased after Vega and Carreon-Lopez in a separate vehicle.

During his sentencing Wednesday, Sonoma County Superior Court Judge Dana Simonds granted Mancinas’ request to close the courtroom while Mancinas pleaded for leniency.

Mancinas has testified he quit the gang life and had provided law enforcement with information about gang activities. He told Simonds he could not speak in public because it would jeopardize his family.

The court was closed for six minutes and Mancinas was then sentenced to 22 years in prison.
