Police arrested a middle school music teacher in San Jose on Friday for allegedly sexually assaulting a student at the school and blackmailing them into a three-year sexual relationship.

KRON 4 said that the teacher's name is Samuel Neipp, originally from Gilroy, California. He worked as a music teacher and at Dartmouth Middle School and as an assistant band director at Branham High School. The 13-year-old student was attending Dartmouth Middle School at the time, and police say that he "used his position of authority to exploit the victim into a sexual relationship." He then allegedly blackmailed the student, threatening to post nude photos unless they kept the "relationship" a secret. KRON 4 also lists the charges currently being placed on Neipp, which include:

  • Lewd and Lascivious Acts with Minor Under 14 (felony)
  • Oral Copulation (felony)
  • Possession of child pornography (felony)
  • Extortion (felony)

The parents of the children who still attend Dartmouth Middle School are shaken by the revelation. ABC 7 spoke with Larry Euley, a parent of one of the children in the band that Neipp oversaw. Euley said, "They're all upset and they have a competition next weekend. So this is throwing a monkey wrench into everything they are trying to rehearse for it." Euley went on to then explain that "[the students] had no clue that any of this was going on."

The school also issued a public statement to parents on their website, where they asked anybody with additional information regarding Neipp's alleged sexual assault to contact the San Jose Police Department. They also asked all parents to tell their children to contact a school administrator if they were subjected to inappropriate conduct.

The San Jose Police Department told ABC 7 on Saturday that they had been fielding calls from parents all day Saturday, with a few coming from potential victims.
