Tanzanian authorities are investigating the death of Ashly Robinson, a 31-year-old US influencer, who was found unresponsive in a luxury resort in Zanzibar, where she was celebrating her birthday and recent engagement with her fiancé, Joe McCann, founder of crypto investment firm Asymmetric. Despite police confirming that Robinson died by suicide, following a heated argument with McCann, they are still investigating her death and have withheld McCann's passport. The couple had been separated twice by hotel staff due to their dispute. McCann, who has an estimated net worth of $45 million, has been questioned by police and has been asked to remain in the country while they await the results of Robinson's autopsy.

Robinson's family has expressed doubts about the initial reports of her death and has set up a fundraising page to cover travel and other expenses. The hotel where the incident occurred has expressed its condolences and is cooperating with the authorities.

McCann's crypto firm, Asymmetric, has been in the news recently after he announced the shutdown of its Liquid Alpha Fund due to significant financial losses.
