SANTA ANA  (AP) — A former Orange County high school teacher who had a long affair with a 15-year-old student has been sentenced to six months in jail.

Thirty-seven-year-old Rebecca Diebolt of Brea was sentenced Friday and ordered to register as a sex offender for life.

She pleaded guilty in January to sex acts with a minor. Diebolt was a language-arts teacher and swimming and water polo coach at Valencia High School in Placentia.

Prosecutors say she began a sexual relationship with the female student in 2004 and it continued until 2008, when the victim was in college.
