After a month of criminal investigations, police are still trying to piece together what happened to the 26-year-old man, whose body was pulled from the water near the Verbois dam, west of the city of Geneva.
In a statement, police said the victim’s name was Arsen Memaj, although he was also known by the name Emaj Ermal.
He was 1.72 centimetres tall and when discovered he was wearing a dark, hooded fleece jacket, blue jeans and “Landrover” ankle boots.
Police believe the man died several weeks before his body was found near the dam under circumstances “which have yet to be established”.
A bridge across the dam links the wine-making village of Russin with the community of Aire-la-Ville.
Police are looking to find out where the man lived and what people he knew in the area in the hope of shedding light on what happened.
The force issued a photo of the man, unshaven, with short hair, wearing a dark t-shirt and a hooded jacket.
The 20 Minutes newspaper reported online that, according its information, the body was found with feet and hands tied.
This information has not been confirmed.
But police say they are not ruling anything out at this point.
Anyone with information about the victim is asked to contact police on 022 427 72 40.
