Joe McCann, the founder of the crypto investment firm Asymmetric, is at the center of an investigation by Tanzanian authorities following the alleged suicide of his fiancée, US influencer Ashly Robinson, during a vacation in Zanzibar. Robinson, a 31-year-old lifestyle creator from Miami, was found unresponsive in a luxury villa at the Zuri Zanzibar resort on April 9, where the couple was celebrating her birthday and recent engagement. She was later pronounced dead at a hospital. According to Zanzibar police, Robinson's death has been confirmed as a suicide following a 'misunderstanding' between the couple, but the investigation is ongoing.

The couple had been involved in a heated argument before being separated by hotel staff, and despite the initial findings, police have withheld McCann's passport and asked him to remain in the country pending the results of Robinson's autopsy. The hotel has expressed its condolences and is cooperating with the authorities. Robinson's family has expressed doubts about the official cause of death and has set up a fundraising page to cover travel and other expenses.

McCann, with an estimated net worth of $45 million, is a well-known figure in the crypto industry, having led Asymmetric, a hedge fund and venture firm backed by prominent investors. However, he recently announced the shutdown of Asymmetric's Liquid Alpha Fund due to significant financial losses.

The incident has sparked widespread media attention, with the US State Department offering its condolences to the Robinson family.
