Brentwood School teacher pleads not guilty to sexually assaulting student

LOS ANGELES (KABC) -- A teacher at the prestigious Brentwood School pleaded not guilty to charges that she had a sexual relationship with an underage student.

Aimee Palmitessa, 45, was charged Friday with a dozen felony counts - seven counts of unlawful sexual intercourse, two counts each of sodomy and sexual penetration by foreign object of a person under the age of 18 and one count of oral copulation of a person under 18.

The victim, a 16-year-old boy, was once Palmitessa's student, according to the Los Angeles District Attorney's Office. Palmitessa is accused of assaulting the boy between June 12 and Aug. 11.

The boy told authorities about the alleged incidents, and Palmitessa was arrested on Aug. 18.

Palmitessa will remain free on bail and has been ordered to not contact the victim. She is set to be back in court Oct. 16 for a preliminary hearing.

Palmitessa has been a biology teacher at Brentwood School for about nine years and is currently on administrative leave.

She's also facing a drug charge from the Coachella Music Festival back in April.

If convicted as charged, Palmitessa faces up to 10 years and four months in state prison.

The case remains under investigation.
