A Southern California orthopedic surgeon - who appeared on Bravo's Online Dating Rituals of the American Male - and his girlfriend are being accused of drugging and sexually assaulting two women in 2016.
Robicheaux appeared on the Bravo reality TV show "Online Dating Rituals of the American Male".
In the first, a 32-year-old woman said she met the couple at a local restaurant in April 2016 and they invited her to a party, authorities say. Grant and Cerissa are then accused of drugging, "raping and orally copulating" the alleged victim who was unable to resist because she was intoxicated and drugged.
Both suspects were arrested Wednesday at Robicheaux's apartment in Newport Beach and have been released on $100,000 bail.
The defense attorneys said Riley is Robicheaux's girlfriend, while Rackauckas referred to her as a "female companion" and "purported girlfriend".
On Oct. 2, 2016, the defendants met the second victim at a bar in Newport Beach and drank with her until she was unconscious. Robicheaux's patients do not appear to be among them, although the investigation remains active. They were both charged on September 11 and are set to be arraigned on October 24. Robicheaux's medical license is under review by the medical board of California.
Prosecutors believe that Robicheaux and Riley also might have assaulted other women at such out-of-town events as Burning Man in Nevada and the Splash House Festival in Palm Springs and are calling on any other alleged victims to come forward. "Well, a wolf can wear scrubs or doctor's clothing, or a wolf can be a handsome woman".
U.S. media outlets reported that prosecutors suspected there could be hundreds - if not thousands - of other victims.
A search of the Robicheaxu's home found illegal drugs, including the date rape drug GHB, Rackauckas said. It's uncertain whether the firearm plays a role in the drugging and sexual assault charges the couple are facing, but Robicheaux is also accused of possessing two unregistered assault rifles, along with additional firearms of large capacity.
Robicheaux faces 40 years in prison if convicted as charged, while Riley faces 30 years and eight months, officials said.
"We've all heard of a wolf dressed up in sheep's clothing but a wolf can wear scrubs or doctors clothing or a wolf can be a lovely woman", he also said.
Robicheaux and Riley were charged with the attacks in January, with lawyers for the couple denying all the accusations made against them.
Dr Grant William Robicheaux billed himself as an elite orthopaedic surgeon catering to the famous and wealthy in the USA state of California.
This undated booking photo provided by the Newport Beach, Calif., Police Department shows Grant W. Robicheaux, 38, a California doctor who appeared in a reality TV dating show. They then allegedly raped her; she was unable to resist due to the drugs in her system, according to authorities.
He said the couple video taped hundreds if not thousands of sexual encounters with women.
"We believe the defendants used their good looks and charm to lower the inhibitions of their potential prey", Rackauckas said.
"These cases have been challenging to investigate, but we have remained dedicated to identifying the suspects and gathering as much evidence as possible to get justice for the victims", spokesperson Jennifer Manzella said.
