An employee in the San Bernardino County District Attorney’s office, who came forward last year revealing she had an 18-month long relationship with District Attorney Mike Ramos after the affair became public, has filed a civil suit against the county and Ramos.

Cheryl Ristow, an investigative technician, resigned from her job this week after more than a year on stress leave. Ristow has previously alleged she was retaliated against after knowledge of her relationship with Ramos was revealed in a local news publication in May 2009.

Ristow has said her employment was placed under scrutiny by her supervisors after she indicated she wouldn’t lie for Ramos.

Ramos has repeatedly denied having any affair with Ristow or any other women under his command.

Sources now say legal documents filed today in San Bernardino County Superior Court clearly label Ramos’ repeated denials as untrue.

Some of the causes of action alleged in the lawsuit include Sexual Harassment, Violations of the Business and Professions Code, Assault and Battery, and Intentional Infliction of Emotional Distress.

Ristow is represented by attorney James Reiss of the Rancho Cucamonga-based law firm of Reiss and Johnson.
