Tanzanian authorities are probing the alleged suicide of Ashly Robinson, a 31-year-old US influencer, during a trip to Zanzibar with her fiancé, Joe McCann, founder of the crypto investment firm Asymmetric. The couple had been celebrating Robinson's birthday and recent engagement at a luxury resort when she was found unresponsive in a private villa on April 9.

Despite police confirming her death as a suicide following a 'misunderstanding' between the couple, the investigation is ongoing, and McCann's passport has been withheld. The couple had reportedly argued and been separated by hotel staff twice before Robinson's death. McCann, who has an estimated net worth of $45 million, has been questioned by police and asked to remain in the country pending the results of Robinson's autopsy.

Robinson's family has expressed doubts about the official cause of death and has set up a GoFundMe page to cover travel costs and other expenses. McCann, a prominent figure in institutional crypto, had recently announced the shutdown of Asymmetric's Liquid Alpha Fund due to significant financial losses. The US State Department has offered condolences to Robinson's family but declined to comment further on the investigation.
