The deaths have been marked by question marks since 21 February 2020 when a woman from Jönköping was found dead in her room in a holiday hotel in Punta Cana in the Dominican Republic.
The day after the woman died, her husband, also from Jönköping, died in police custody, where he was taken to be questioned about his wife's death.
Relatives of the couple have asked the Ministry of Foreign Affairs for help in sorting out the course of events, Jönköpings-Posten has previously reported.
