Accessory agrees to testify against co-defendants in Fontana shooting case

An alleged accessory to a September shooting in Fontana has agreed to testify against two alleged gunmen in exchange for a favorable plea deal from prosecutors.

Prosecutors say Daniel Casas, 23, served as the driver on Sept. 2 for two alleged gang members accused of ambushing a father and son who confronted the men while they were tagging in Fontana.

If Casas testifies against the two alleged shooters -- Angel Valencia, 19, and Andrew Valdivia, 19 -- he will be sentenced to a year in county jail in exchange for his plea, said Deputy District Attorney Doug Shaller.

A man and his teenage son confronted Valdivia and Valencia with baseball bats while the two alleged gang members tagged a wall in their neighborhood.

Valdivia and Valencia stopped tagging and left the area, then allegedly enlisted Casas to drive them to the man and son's home to retaliate, according to police.

The two alleged gang members shot the man once in the back and once in the neck, but he survived his injuries, Shaller said. The man's teenage son was not hurt.

Casas agreed to the plea offer last week when he, Valdivia and Valencia were set to face a preliminary hearing in Fontana Superior Court.

Casas agreed to plead no contest to a felony accessory charge. As part of Casas' plea deal prosecutors will dismiss two counts of attempted murder.

If Casas does not testify against Valdivia and Valencia he will be sentenced to seven years in state prison, Shaller said.

During last week's preliminary hearing -- held for Valdivia and Valencia -- two Fontana police officers who worked on the case testified about the incident, Shaller said.

Casas is set to testify when the preliminary hearing resumes on Tuesday, Shaller said.
