2 New Mexico Teen-Agers Charged With Zuma Killing : Courts: The evidence against a third youth is being reviewed. Detectives believe the motive was money and a car to get them home.

Los Angeles County prosecutors on Friday filed murder charges against two New Mexico teen-agers accused of fatally stabbing a Northridge woman at Zuma Beach in Malibu and said they would continue to review evidence against a third youth.

The murder charges included special circumstances--lying in wait and murder during the commission of a robbery--that would send the youths to prison for life without possibility of parole if they are convicted of killing Jacqueline Kirkham, 43, for her money and her car.

Charged with murder and second-degree robbery Friday were Michael Loretto, 17, and Guillermo Bustos, 16, both of Pojoaque, N.M. They are being held in a Santa Fe County juvenile center on New Mexico charges.

Their companion, 17-year-old Jason Alexander, was also in custody in New Mexico.

Los Angeles Deputy Dist. Atty. Harvey Giss said he was still “trying to ascertain the exact facts as they apply” to Alexander, but a spokeswoman for the prosecutor’s office said charges against the youth were expected.

Alexander’s attorney, George Adelo, said Friday that Alexander was not involved in the robbery and killing of Kirkham, whose sports car was found abandoned outside Santa Fe.

“He is not involved in any aspect of the alleged assault. That’s why he hasn’t been charged,” Adelo said. “This is the classic example of being in the wrong place at the wrong damn time.”

Crime reports were sealed Friday because of the continuing investigation, and officials declined to discuss details.

But law enforcement sources said Bustos stabbed Kirkham after Loretto tried to take her purse.

Detectives have said all three youths fled New Mexico by bus when they realized they were being investigated for the May 10 burglary of a bar, then attacked Kirkham on May 28 because they needed money and transportation to return home.

Los Angeles County prosecutors also filed papers Friday asking that the two charged teen-agers be extradited to California. Their return could take place in days or weeks, depending on whether they fight the extradition efforts.

Loretto’s attorney in New Mexico, Public Defender Todd Wertheim, declined to comment on the charges. He said no decision had been made whether to fight extradition.

An attorney for Bustos could not be reached, and Adelo said he would fight extradition.
