Friendship with Anna Sorokin
Duke became affiliated with Anna Sorokin, a Russian con artist posing as a German heiress using the name "Anna Delvey", when she was hired to be Sorokin's personal trainer and life coach. Sorokin, who had found Duke online, paid Duke $4,500 in cash for a package of sessions. Duke accompanied Sorokin and Rachel DeLoache Williams on a trip to La Mamounia in Marrakech in May 2017. She was sick for the majority of the vacation, and booked a flight back to the United States with Williams' help. After Duke left Morocco, Sorokin pressured Williams to pay for the $62,000 trip when her credit card was declined. After Sorokin started experiencing financial trouble and was kicked out of the hotel she had been residing at, Duke let her stay at her apartment.
