Arraignment delayed for Chino Hills music teacher

CHINO -- An arraignment hearing was delayed today for a Chino Hills High School music teacher accused of having a sexual relationship with an underage student.

Justin Clark Wallin, 30, left Chino Superior Court without entering a plea because prosecutors have not yet filed criminal charges in his case. He is scheduled to return to court Nov. 12.

Wallin was arrested in July for allegedly having a sexual relationship with a 16-year-old girl.

The relationship was reported to authorities after the girl's parents discovered more than 8,000 text messages -- some sexually explicit -- sent by Wallin to their daughter, San Bernardino County sheriff's officials said.
