Greta Marie Otteson, a 33-year-old woman from Britain, and her South African fiancé Els Arno Quinton, 36, were found dead in their room at the Vietnam hotel where they were staying. Allegedly, the two had limoncello that was toxic because of the presence of methanol in it.

The couple, who were spending Christmas in the coastal city of Hoi An, announced their engagement just days prior to their untimely deaths through a YouTube video.

Greta and Els moved to Vietnam in February of last year.

Authorities believe that the couple ordered ‘homemade’ limoncello from a local restaurant that could have been laced with methanol.
“Police forensics established the limoncello, which had been delivered, was the source,” a source close to the victims’ families shared with The Times.

Greta sent a text message to her family, complaining about experiencing the “worst hangover ever.” She was also seeing “black spots” in her vision.
