Robicheaux, 38, and Cerissa Laura Riley, 31, were taken into custody Sept. 12 on multiple charges, including “rape by use of drugs.” Orange County District Attorney Tony Rackauckas said in a news conference that the investigation into the pair began in October 2016. Police were called to Robicheaux’s Newport apartment on Oct. 2, 2016, after a neighbor called 911 when he or she heard a woman screaming. The alleged victim said she was sexually assaulted by Robicheaux and Riley when they brought her to his home after meeting them at a bar, where she drank “until she was unconscious,” according to The Associated Press. A 32-year-old woman claimed she was assaulted by the pair in April 2016 after meeting them at a local restaurant. She told police she “consumed large amounts of alcohol” before going to Robicheaux’s home for an after-party, according to the Los Angeles Times. Prosecutors claim the woman was then drugged and sexually assaulted. The AP said “a forensic exam found multiple controlled substances” after she called police the day after the alleged incident. On Jan. 9, 2018, authorities searched Robicheaux’s home and allegedly found unregistered firearms and large amounts of illegal drugs, including GHB, according Rackauckas. In a press conference, Rackauckas also said investigators were combing through “thousands and thousands of videos and images on Robicheaux’s phone, many also including Riley.” Some videos reportedly show women who are inebriated and “barely responsive to the defendant’s sexual advances,” leading investigators to believe there are other victims. Robicheaux, a board certified orthopedic surgeon, was featured on a 2014 reality dating show that aired on Bravo, “Online Dating Rituals of the American Male.” Orange Coast Magazine also named him “Orange County’s Most Eligible Bachelor” in 2013, according to the LA Times.
