MINNEAPOLIS — A Minnesota man says his family has been given little information on how his two sisters died while vacationing on a tropical African island.

The bodies of Annie Korkki, 37, of Denver, and Robin Korkki, 42, of Chicago, were found in their resort villa last week in Seychelles, an archipelago nation off Africa’s east coast in the Indian Ocean.

Their brother, Chris Korkki, of Lakeville, said the family has learned nothing through official channels about his sisters’ deaths.

“At this point, the only details we know are the articles flying around online,” Chris Korkki told the Star Tribune . “My mom has been talking with people from the U.S. Embassy. I don’t think they’ve provided her with any information.”

Emails sent by The Associated Press to police and the foreign ministry in Seychelles weren’t immediately returned Thursday.
