Case # 18HF1291

Date: September 21, 2018


SANTA ANA, Calif. – Since the Orange County District Attorney’s Office (OCDA) has been made aware of the allegations involving Defendants Robicheaux and Riley, we have been diligently pursuing justice on this case consistent with our ethical responsibilities. Prosecutors and Investigators in the Sexual Assault Unit of the OCDA were instrumental in rekindling the investigation on this case after learning about it through a “DNA cold-hit” on a case related to these defendants. All law enforcement investigations require a full and complete analysis of all available evidence. The very nature of sexual assault cases and the inherent difficulties involved in investigating such allegations often require additional measures to garner the required corroboration to obtain evidence necessary to fulfill our prosecutorial burden of proof beyond a reasonable doubt.

The OCDA and the Newport Beach Police Department (NBPD) have worked together since September 2017 to obtain all available evidence in this case. There have been several meetings between the two agencies with that goal. Much of the information required in this prosecution involved the need to obtain, decrypt, and analyze terabytes of digital evidence through search warrants from technology companies. The OCDA is committed to protecting the public and is determined to devote all necessary resources to investigate the leads that have arisen in this case and to obtain justice for all the courageous survivors who have so bravely come forward to report their victimization at the hands of these defendants.

The timeline of the People v. Grant Robicheaux and Cerissa Riley case before filing is as follows:

  • April 10, 2016 – The defendants are accused of supplying multiple drugs to Jane Doe 1 then raping and orally copulating her while she was prevented from resisting due to intoxicating and controlled substances and they should have reasonably known of her condition.
  • April 12, 2016 – Jane Doe 1 contacted the NBPD and underwent a forensic exam, which tested positive for multiple controlled substances.
  • Oct. 2, 2016 – Robicheaux and Riley are accused of drinking alcohol with Jane Doe 2 at a bar in Newport Beach until the victim was no longer conscious. The defendants are accused of bringing Jane Doe 2 to Robicheaux’s apartment and sexually assaulting her with intent to commit rape. Jane Doe 2 awoke and screamed for help until a neighbor called NBPD, who responded to the scene and investigated this case.
