MURRIETA (Wire Service) - A former Vista Murrieta High School band instructor accused of making sexual overtures to a 15-year-old student and showing her pornography pleaded not guilty today to three counts of annoying a minor.

Garrett Bayly Karlin, 24, could face jail time and fines if convicted of the misdemeanor charges, which authorities say stem from his contact with a member of the high school band.

Karlin remains free on $3,500 bail. A trial-setting conference is scheduled in the case for March 25.

According to Murrieta police, Karlin Advertisement

Karlin had met the student while working part-time for the Murrieta Valley Unified School District as a summer band camp coach, a position he no longer holds.

During private encounters with the youth, Karlin allegedly made inappropriate suggestions and showed her sexually explicit material, police said.

The alleged incidents came to light in November, leading to an investigation that culminated in Karlin's arrest on Nov. 20 at his home.
