Gardaí say a man killed in Co Westmeath earlier this week was violently assaulted and died as a result of his injuries.
The body of 65-year-old Stefan Nivelles Posschier from Rattin, near Kinnegad, was found at his home on Tuesday evening.
It is understood a relative raised the alarm after they found Mr Posschier with serious injuries.
As part of the investigation gardaí say they now want to speak to anyone who met or saw Mr Posschier or interacted with him on social media in the days prior to his death.
A well-known tarot card reader and fortune teller, Mr Posschier had been living in the area for more than 20 years.
Gardaí say an incident room has been set up at Mullingar Garda Station and a family liaison officer has also been appointed.
Investigating gardaí can be contacted at Mullingar Garda Station on 044 9384000 or on the Garda Confidential Line 1800 666 111 or through any garda station.
Gardaí said no arrests have been made.
