MARTINEZ -- Three Hayward men have been ordered to stand trial on murder charges for an accomplice's death during a San Ramon jewelry store heist last year, a prosecutor said Friday.

Krishneel Prasad, 20, Gregory Jamal Louis, 22, and Michael Porter, 21, were held to answer for murder and three counts of robbery on Thursday after a two-day preliminary hearing in Contra Costa County Superior Court, said deputy district attorney Jason Peck.

Authorities continue to look for an alleged fourth robber wanted on the same charges: 20-year-old Hayward resident Manuel Jovan Arroyo.

The owner of the Gold N Treasures store on San Ramon Valley Boulevard shot and killed 18-year-old Kibrom Bairu in self-defense during the May 30 robbery, authorities say. Bairu was allegedly threatening the owner and his employees with a gun at the time.

His alleged accomplices are charged with murdering him under the provocative act doctrine, which holds active crime participants liable for a homicide when it occurs in the course of the crime.

Prasad assaulted a store employee, and Porter gathered the jewelry during the holdup, Peck said. Louis allegedly served as the getaway driver. Louis and Prasad were arrested in June, and Porter was captured months later in Mississippi.

Police are asking for the public's help in finding Arroyo, a 5-foot-5-inch, 150-pound man of African-American and Latino descent. He has black hair and hazel eyes, as well as multiple tattoos on his arms and on the right side of his neck. He is known to live in Hayward but also has connections to the Walnut Creek area.

Prasad, Louis and Porter return to court April 8. All three remain in jail custody.

Prasad and Louis' bail is $1 million. Porter's bail is higher, $2.9 million, because he was on parole for robbery at the time of the San Ramon incident.
