Tributes paid as British tourist and fiancé found dead in Vietnam villa days after engagement video

Tributes have been pouring in for a couple who were found dead in a villa in Vietnam just days after announcing their engagement.

British tourist Greta Marie Otteson and her South African fiancé Els Arno Quinton recently became engaged, having posted a video announcing their milestone on YouTube days prior to their passing.

Greta was just 33-years-old, while husband-to-be Els was just 36, when their bodies were found in separate rooms in the same villa on Boxing Day, after a cleaner came to the holiday home located in Hoi An Town in central Quang Nam province.

Authorities are now investigating the tragic incident, with police officers finding empty bottles of wine at the scene.

Red Eye Studios posted a montage they made of the couple to celebrate their upcoming marriage, with the video showing Greta and Arno dancing and holding hands in all-white.

The tribute was posted with a description, reading: "Living in the romantic city of Hoi-An, our good friends Greta and Arno decided to surprise their families with a beautiful video to announce their engagement.

"This shoot was charged with so much emotion, reminding us how powerful the union of two souls can be.

"Congratulations to you both from everyone here at Red Eye Studios! We will miss you great souls…"

It is believed that they became engaged in December.

A Quang Nam Provincial Police spokesperson stated: "There were no signs of ransacking at the scene. The victims' belongings and phones were untouched."

There's said to be no signs of scratches or physical trauma on the bodies, though empty liquor bottles have been collected from the room for analysis.

The pair had been staying at the tourist villa since July, though Greta is known for enjoying her travels, having lived in Dubai and backpacked around Asia before settling in Vietnam.

Arno's friend Dayle Visser took to social media to share an emotional tribute, writing: "Rest in peace my brother. Thank you for always being the fierce friend you were. You saved me many a time.

"You were real and lived life harder than most people could ever dream of. I love you and I will always miss you."

One of Greta's friends added that she loved him 'unconditionally' as his 'bedrock', adding that she gave him the freedom to do what he wanted in life.

They added: "There are two distinct things that are so prominent in my thoughts and that is her laugh and how much love they constantly [threw] at each other, regardless of who was around.

"They celebrated each other there and I know they will continue doing that, wherever they are."

A Foreign Office spokesman stated: "We are supporting the family of a British woman who has died in Vietnam and are in contact with the local authorities."
