An area close to his farmyard has been declared a crime scene.
Suspected human body tissue has been found in the search for Michael Gaine in County Kerry.
An area close to his farmyard has been declared a crime scene, and the State Pathologist has been called.
The 56 year old disappeared in March, with the case upgraded to a homicide investigation last month.
Gardaí have been onsite at Mike Gaine's farm in Carrig East, just outside Kenmare, since first light this morning.
A number of Garda vehicles are present, and Gardaí can be seen moving between the farmyard and two nearby fields, where slurry was spread yesterday.
At least six yellow, evidence markers can be seen across the two fields where the slurry was spread.
Last night, Gardaí said a scene closed to the farmyard had been sealed off and a forensic and technical examination will be carried out today.
