Former Whitney High teacher sentenced to prison for sexual relationship with student

A former Whitney High School teacher has been sent to prison for having a sexual relationship with a student, according to authorities.

Placer Superior Court Judge Michael Jones sentenced Matthew Scott Yamamoto to four years and eight months in prison, a news release from the District Attorney’s office states.

The judge found that Yamamoto, who was 33 years old at the time of his September 2012 arrest, had violated his position of authority over the 17-year-old victim and that he “essentially robbed her of her high school years” – factors that outweighed his lack of criminal history and “strong family support,” according to the news release.

The judge also noted that Yamamoto taught his victim how to destroy evidence and create fictitious email accounts to foil police, the news release states. He also repeatedly violated the restraining order imposed in the case, according to the release.

In October, Yamamoto pleaded no contest to oral copulation with a minor, attempted sexual intercourse with a minor and sexual penetration with a foreign object on a minor, all felonies, the release states. He pleaded guilty to one felony count of conspiracy to obstruct justice.

Yamamoto will have to register as a sex offender upon release from prison.

The District Attorney’s office stated in its release that it was satisfied with the sentence.
