An investigation is ongoing in Tanzania into the death of Ashly Robinson, a 31-year-old US influencer, who was found unresponsive in a luxury resort in Zanzibar. Her fiancé, Joe McCann, the founder of crypto investment firm Asymmetric, is being probed by the authorities. The couple had been celebrating Robinson's birthday and recent engagement at the resort when they got into a heated argument, according to hotel staff.

Despite initial reports suggesting Robinson died by suicide, the police are still investigating her death and have withheld McCann's passport. McCann has been questioned by the police and has been asked to remain in the country while the authorities await the results of Robinson's autopsy.

The hotel where the incident occurred has expressed its condolences to Robinson's family and is cooperating fully with the investigation. Robinson's family has set up a fundraising page to help cover the costs of travel and other expenses, and has raised over $50,000. McCann, who has an estimated net worth of $45 million, is a prominent figure in the crypto industry, but has recently faced challenges, including the shutdown of his firm's Liquid Alpha Fund due to significant financial losses. The US State Department has offered its condolences to Robinson's family but has declined to comment further on the investigation.
