Two sisters from Minnesota described by their brother as "experienced foreign travelers" were found dead last week while on vacation in the Seychelles, an archipelago off the east coast of Africa—and no one yet knows why, CBS Minnesota reports. Workers at the Maia Luxury Resort on the island of Mahe say they spotted Robin Korkki, 42, and Annie Korkki, said to be 37 or 38, kicking back with drinks throughout the day on either Sept. 21 or 22 (reports differ) and that they were assisted to their room around 8:15pm, the Seychelles Nation reports, via People. The next day, the sisters were found "unresponsive" in their beds by staff, with no obvious signs of trauma. "There were no marks on them whatsoever," the Seychelles tourism minister tells NBC News.
Medication was found in the women's villa, though police haven't said what kind. Autopsies are scheduled for this week, the Nation notes. "At this point, the only details we know are the articles flying around online," their brother, Chris Korkki, tells the Star Tribune, describing his sisters as adventurers who "definitely wanted to experience life to the fullest." The sisters were a week into their trip at the $2,000-per-night luxury resort when they were found dead; they were due to depart for home on Sept. 24, the Seychelles News Agency reports. CBS notes that both local authorities and the US Embassy are involved in trying to figure out what happened. Meanwhile, more than $25,000 has been raised so far on a crowdfunding page for the sisters' family.
