The man whose body was found in a flat in Limerick yesterday has been named locally as 45-year old Martin Clancy, from Limerick city.
The State Pathologist Professor Marie Cassidy arrived at the scene this lunchtime ahead of conducting a post mortem later today.
The results of the autopsy will help gardaí decide the course of their investigation.
Gardaí are understood to be treating the death as suspicious.
Mr Clancy's neighbours paid tribute to him today.
"Quiet, lovely person, sound out, kind," said one neighbour.
"He took everyone that was homeless in off the streets kind-of-thing.
"He was a good person.
"Two weeks ago, I was just talking to him at the door and he was doing ok because I had brought him over food and whatever."
Another neighbour said: "I knew Martin very well. He was very quiet, he didn't bother anyone.
"Martin was always walking his dogs. His two dogs he was always out with."
