Joe McCann, the founder of Asymmetric, a crypto investment firm, is under investigation by Tanzanian authorities after the alleged suicide of his fiancée, US social media influencer Ashly Robinson, during their trip to Zanzibar. Ashly Robinson, a 31-year-old lifestyle creator from Miami, was found unresponsive in a private villa at the luxury Zuri Zanzibar resort, where the couple was celebrating her birthday and recent engagement. She was pronounced dead at a hospital.

According to Zanzibar police, Robinson's death has been confirmed as a suicide following a 'misunderstanding' between the couple. However, the police have not ruled out other possibilities and are still investigating. The couple had a heated argument before being separated by hotel staff and sent to different rooms.

McCann has been questioned by the police and has been asked to stay in the country until the forensic results from Robinson's autopsy are available. The hotel has expressed its condolences and is cooperating fully with the local authorities and the US Embassy.

Robinson's family has expressed doubts about the cause of death and has set up a GoFundMe page to raise $50,000 for travel costs, arrangements, and other expenses. They have exceeded their target. McCann, with an estimated net worth of $45 million, is a prominent figure in the crypto industry, leading 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 couple had traveled to Zanzibar on April 4, according to a statement from Tanzanian police.

The US State Department has offered its condolences to the Robinson family but has no further comment on the investigation.
