An investigation is underway in Tanzania 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 questioned 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. The hotel has expressed its condolences and is cooperating with the local authorities. Robinson's family has set up a fundraising page, expressing doubts about the official cause of death.

McCann, a prominent figure in the crypto industry, has an estimated net worth of $45 million and has been leading Asymmetric, a hedge fund and venture firm backed by notable investors. The US State Department has offered its condolences to the Robinson family but declined to comment further on the investigation.
