SAUGUS, Calif. (KABC) -- The Los Angeles County District attorney's office has reportedly declined to file charges against the mother of the shooter at Saugus High School last year.
The county sheriff's department had presented two charges against Mami Matsuura-Berhow, the mother of 16-year-old Nathaniel Tennosuke Berhow.
The teen opened fire with a gun assembled at home -- shooting five schoolmates, including two who were fatally wounded, before before taking his own life on Nov. 14 -- his birthday.

The Santa Clarita Valley Signal says detectives wanted to charge Berhow's mother for contributing to the delinquency of a minor and criminal storage of a firearm.
However, the case was rejected last month due to lack of evidence.
The anniversary of the shooting is Saturday.
