Joe McCann, the founder of Asymmetric, a cryptocurrency investment firm, is at the center of an investigation in Zanzibar, Tanzania, following the alleged suicide of his fiancée, Ashly Robinson, a US influencer. The 31-year-old lifestyle creator was found unresponsive in a private villa at the luxury Zuri Zanzibar resort, where the couple was celebrating her birthday and recent engagement.

Despite initial confirmation of suicide, the police are still investigating her death, citing a prior argument between the couple. McCann's passport has been withheld, and he has been asked to remain in the country pending the outcome of the forensic examination of Robinson's autopsy. The hotel has expressed its condolences and is cooperating with the authorities.

Robinson's family has raised concerns over the circumstances of her death, setting up a GoFundMe page to cover expenses. McCann, with an estimated net worth of $45 million, is a prominent figure in the crypto industry, having led Asymmetric, a hedge fund and venture firm backed by notable investors. However, the firm's Liquid Alpha Fund was shut down in December due to significant financial losses. The US State Department has offered its condolences to the Robinson family, while the Tanzania Police Force has not responded to requests for information.
