A former Saugus High School substitute teacher was sentenced to state prison Wednesday after pleading no contest to sexually assaulting one of his female students over two months.

David Cornish, 28, pleaded no contest to lewd acts upon a child aged 14 or 15 on Wednesday, and was sentenced to three years in state prison, said Ricardo Santiago, spokesperson for the Los Angeles County District Attorney’s Office.

A 10-year protective order was issued and he was ordered to register as a sex offender, according to Santiago.

Cornish was originally charged in May of 2020 on five counts each of lewd act upon a child, sexual penetration of a person under the age of 18, oral copulation of a person under the age of 16 and one count each of meeting a minor for lewd purposes, contact with a minor for a sexual offense and distributing or showing child pornography to a minor, according to Greg Risling, spokesperson for the Los Angeles Country District Attorney’s Office in a previous article.

On June 22, Cornish pleaded not guilty to the charges, according to the D.A.’s Office.

Over two months, the defendant is accused of having an unlawful sexual relationship with a 14-year-old girl he taught at Saugus High School. Cornish was arrested Wednesday, May 27 2020 after the victim reported the relationship to investigators.

On Tuesday, May 26, 2020, investigators from the Los Angeles County Sheriff’s Department’s Special Victims Bureau began investigating the circumstances involving an unlawful sexual relationship between a substitute teacher and his female student between the months of April and May 2020.

The victim disclosed to investigators that she had been involved in a sexual relationship with her substitute teacher, Cornish, according to Deputy Grace Medrano.

The William S. Hart Union School District is “deeply concerned that one of our substitute teachers, David Cornish, was arrested and is expected to be charged with engaging in sexual misconduct with a Saugus High School minor student,” said a district spokesperson in a statement.

“The district strives to provide a safe educational environment for all of our students, and we are saddened and disturbed that one of our substitute teachers is being charged with this misconduct,” Hart district officials said.

The Hart District immediately suspended Cornish upon learning of the allegations, according to the spokesperson.
