Detectives have confirmed a driving licence, bank card and mobile phone are missing from the man whose body was found in a field two days ago.
Deniss Timosejeves, 22, went missing after going for a walk from his home at Thornleigh Place, Applewood, Swords, Co Dublin, on Easter Monday.
The shop worker, who was a qualified computer engineer and originally from Ludza in Latvia, was discovered the next day in nearby farmland at Balheary with a broken arm and internal injuries.
Gardaí are trying to locate a number of personal items missing from the deceased, including a Latvian driving licence, a bank card bearing his name and a mobile phone.
Superintendent Ronan Galligan of Swords garda station said the force was now treating the death as suspicious.
“I wish to stress that this investigation is at a very early stage and we are committed and determined to discover who was involved in his death,” he added.
It was originally thought Mr Timosejeves may have fallen from a mobile phone mast near where his body was discovered, but it is now suspected he may have been killed – possibly in a hit and run – before his remains were moved to the scene.
Investigators have appealed for anyone who was in the Applewood or Balheary area on Monday evening and who may have seen him to get in contact.
When last seen, Mr Timosejeves was wearing a “distinctive” FC Barcelona scarf and an orange and black jacket. He was 5ft tall and of slight build.
He was living in Ireland since 2011.
“He came over here a young man, trying to make a living,” said Supt Galligan. “He was working in the Swords area, he was very well respected by his employers and by the people who knew him well.”
Detectives said some of his personal possessions – including a silver Sony Ericsson slide phone, his Latvian driving licence and AIB bank card – were missing when his body was discovered.
Liaison officers have been appointed to deal with a number of Mr Timosejeves’ relatives in Swords as well as in Latvia.
Gardaí said they would not release the details of a post mortem examination carried out by Deputy State Pathologist Khalid Jabber because of “operational reasons”.
