SYLMAR : Murder Charge Filed in Pizzeria Slaying

A 17-year-old suspected of killing an assistant manager at a Porter Ranch pizzeria was charged with premeditated murder Monday by the Los Angeles County district attorney.

Dusty Tyrone Castillo, who prosecutors will argue should be tried as an adult, was also charged with using a firearm during the commission of a crime, which would add two years to his sentence.

Castillo was arrested Friday in San Luis Obispo on suspicion of killing John Michael Holden, 19, during a Jan. 14 holdup at the Ameci In & Out Pizza & Pasta restaurant, police said.

According to police, two teen-age robbers entered the restaurant at 11229 Tampa Ave. about 6:30 p.m. and demanded money from Holden, a part-time student at Moorpark College. Holden handed over $450, but a robber shot him once in the upper torso anyway.

Two other teen-agers arrested shortly after the killing are being tried as adults and were in San Fernando Superior Court on Monday for a pretrial hearing. Both say they are innocent.

Castillo, who is being held at Sylmar Juvenile Hall, was scheduled for arraignment at 8 a.m. today.
