Crypto fund manager under investigation in Tanzania after fiancée's death

Joe McCann, founder of the crypto investment firm Asymmetric, is being investigated by local authorities in Zanzibar, Tanzania, in connection with the death of his fiancée, Ashly Robinson, CoinDesk reported. According to local police, Robinson entered the country with McCann on April 4 and was found unconscious in a villa on April 9 before being pronounced dead after transport to a hospital. Police confirmed that the couple had argued so violently that hotel staff had to separate them into different rooms on two occasions. While authorities are treating the death as a suicide, they have confiscated McCann's passport and barred him from leaving the country until an autopsy is completed, citing the ongoing investigation. McCann has led Asymmetric, which is backed by Andreessen Horowitz (a16z). Last December, he announced the liquidation of the firm's Liquid Alpha Fund amid rumors that it had lost 78% in 2025.
