Autumn Radtke, the 28-year-old CEO of virtual currency exchange First Meta, has died. According to multiple reports, suicide is suspected, but not confirmed.

The Daily Mail cites “police sources” as saying they have “strongly suspected” suicide, and reports that she was discovered in her Singapore apartment on February 28th. Officials are reportedly awaiting toxicology test results to determine the cause of death.

A message on the First Meta Exchange site says, “The First Meta team is shocked and saddened by the tragic loss of our friend and CEO Autumn Radtke. Our deepest condolences go out to her family, friends and loved ones. Autumn was an inspiration to all of us and she will be sorely missed.”

Some of the stories about Radtke are playing up the Bitcoin angle, with at least one calling her “Bitcoin CEO,” but according to a post from September (via Business Insider) about the currencies First Meta Exchange supports, it only supports selling Bitcoin, while offering much greater support (like buying, depositing and withdrawals) of a number of other currencies, including Linden dollars.

Here’s a 2012 presentation Radtke gave on the “past and the future” of virtual currency trading:
