Former music teacher pleads guilty in sexual relationship with student

CHINO -- A former music teacher at Chino Hills High School has pleaded guilty to two felonies for allegedly having a sexual relationship with a 16-year-old girl.

Justin Clark Wallin, 31, pleaded guilty Monday in Chino Superior Court to two counts of unlawful sexual intercourse with a minor.

His pleas were entered as part of a plea agreement with prosecutors that carries a sentence of a year in jail. Wallin is scheduled to be sentenced April 21.

Wallin was arrested in July after the girl's parents discovered more than 8,000 text messages -- some sexually explicit -- sent by Wallin to their daughter, who was a student at Chino Hills High School.

The San Bernardino District Attorney's Office filed a seven-count criminal complaint against Wallin in January.

In exchange for Wallin's guilty pleas, prosecutors have agreed to drop three counts of oral copulation, one count of sexual penetration, and a misdemeanor for annoying or molesting a child.

Wallin was initially free on bail after his arrest, but he was taken back into custody Jan. 7 at his arraignment, when a judge raised his bail from $100,000 to $275,000.

Wallin remains in custody at West Valley Detention Center in Rancho Cucamonga.
