Tanzanian authorities are investigating the death of Ashly Robinson, a US social media influencer, whose fiancé, Joe McCann, a prominent cryptocurrency fund manager, is being questioned in connection with the incident. Robinson, 31, was found unresponsive in a luxury resort villa in Zanzibar, where the couple had been celebrating her birthday and recent engagement.

Despite initial findings suggesting she died by suicide, police have withheld McCann's passport and are awaiting the results of a forensic autopsy. The couple had reportedly argued, with hotel staff intervening to separate them twice.

Robinson's family has expressed doubts about the circumstances of her death and has set up a fundraising page to cover expenses. McCann, founder of crypto investment firm Asymmetric, has an estimated net worth of $45 million and is a well-known figure in the institutional crypto space. The incident has sparked widespread attention, with the hotel offering its cooperation to the authorities and the US Embassy. The US State Department has offered its condolences to Robinson's family but declined to comment further on the investigation.
