Robicheaux is charged with:

• Rape by use of drugs

• Oral copulation by anesthesia or controlled substance

• (4) Possession of a controlled substance for sale

The DA’s office said that In April 2016, Robicheaux and Riley met a  32-year-old Jane Doe 1 at a restaurant in Newport Beach.

On April 10, 2016, Robicheaux and Riley are accused of inviting the victim to a party in Newport Beach and escorting her to Robicheaux’s apartment once she was intoxicated.

The two are accused of supplying multiple drugs to the victim 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.

Jane Doe 1 contacted the Newport Beach Police Department (NBPD) the next day and underwent a forensic exam, which tested positive for multiple controlled substances.

On 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.

A search on  Jan. 9, 2018, Robicheaux and Riley were found to possess large quantities of illegal drugs which were recovered in Robicheaux’s residence.

Robicheaux is also accused of possessing two illegal, unregistered assault rifles, four other firearms, and several large capacity magazines.

New Port Beach police submitted the case to the Orange County District Attorney’s Office for review on Sept. 6, 2018, and arrested the defendants at Robicheaux’s residence on Sept. 12, 2018.

“The defendants may have traveled together to various festivals and locations since 2015 including Burning Man in Black Rock Desert, Nevada, Dirtybird Campout festival in Silverado, Splash House festival in Palm Springs, and landmarks near Page, Arizona”

“Robicheaux also appeared on the Bravo television show “Online Dating Rituals of the American Male.”

“Law enforcement investigating this case believe there may be additional victims.”

Prosecutors say they found a vast quantity of porn videos depicting other women and they are trying to identify additional victims.
