Two sisters were found dead while on vacation.

According to CNN, Americans in Annie Korkki, 37, and Robin Korkki, 42, were vacationing in Seychelles. Just two days before they were planning on heading home, they were found unresponsive in their villa.

However, it is still unclear what caused them both to die.

“Preliminary examination done by the police on their bodies did not show any signs of violence,” said Seychelles police spokesman Jean Toussaint.

Both of the girls were originally from Minnesota. Annie later moved to Denver, while Robin moved to Chicago.

Korkki’s family members have been left without answers since the girls’ shocking passing.

“At this point, the only details we know are the articles flying around online,” their brother, Chris Korkki, said. “Two things keep going through my mind: This isn’t happening, and we just want answers.”

Neither Toussaint nor the US Embassy have released further details. This situation continues to be under investigation.
