An inquiry is being conducted by Tanzanian authorities into the death of Ashly Robinson, a US social media influencer, who was found unresponsive in a luxury resort in Zanzibar. Her fiancé, Joe McCann, founder of the crypto investment firm Asymmetric, is being investigated in connection with her death. The couple had been celebrating Robinson's birthday and their recent engagement at the Zuri Zanzibar resort when they got into a heated argument, according to hotel staff.

Although the police initially confirmed that Robinson died by suicide, they are still investigating the circumstances surrounding her death. As a result, McCann's passport has been withheld, and he has been asked to remain in the country pending the outcome of the forensic results from Robinson's autopsy.

The hotel has expressed its condolences to Robinson's family and is cooperating fully with the local authorities and the US Embassy. Robinson's family has expressed doubts about the official cause of death and has set up a fundraising page to cover travel costs and other expenses. McCann, who has an estimated net worth of $45 million, is a prominent figure in the crypto industry, but his firm has faced significant financial losses in recent times. The US State Department has offered its condolences to Robinson's family but has declined to comment further on the investigation.
