Yamamoto appealed the sex offender registration requirement, arguing that there was insufficient evidence that it was necessary to protect the public. A state appellate court disagreed and upheld the trial court’s decision.
Yamamoto was 33 when he was arrested in September 2012. According to a story in The Sacramento Bee, Rocklin police said they initiated an investigation after receiving a call from a parent who suspected an inappropriate relationship with a 17-year-old student.
