A 50-year-old Huntington Beach woman was arrested Tuesday, Nov. 7 on suspicion of lying under oath to protect her boyfriend who was on trial for suspected sexual assault of a 13-year-old girl, prosecutors said on Tuesday.

Cynthia Marie Dunaway-Erickson was arrested on a felony warrant filed on Thursday, Nov. 2 alleging perjury under oath and accessory after the fact, according to the Orange County District Attorney’s Office.

Dunaway-Erickson’s boyfriend was Jeffrey Scott Jones, who was convicted last year of sexual assaulting a 13-year-old girl in the woman’s care, authorities said. Jones, 57, was a teacher of Advanced Placement English classes at the Libra Academy in Huntington Park when charges were filed.

He slashed his throat with a razor blade moments after jurors found him guilty. His injuries were nonlife-threatening, and he was sentenced in March to 46 years to life in prison for the crimes that occurred in Huntington Beach.

Prosecutors said Dunaway-Erickson lied during her testimony about how Jones’ semen was found inside the victim so he’d avoid conviction. Dunaway-Erickson and Jones’ attorney used the defense that the accusations from the girl were false and she was angry at Jones for trying to structure her life.

If convicted, Dunaway-Erickson faces five years and four months in prison.
