A garda scenes of crime manager has told the Tipperary murder trial that traces of blood were found in a number of places when they searched the house of farm owner Mary Lowry.

Retired detective John Grant was giving evidence in the trial of Patrick Quirke of Breanshamore, Co Tipperary who is accused of murdering Bobby Ryan, a part time DJ known as Mr Moonlight.

Mr Quirke has pleaded not guilty to the murder of Mr Ryan at an unknown location on a date between 3 June 2011 and 30 April 2013. Mr Ryan's body was discovered by Mr Quirke on a farm at Fawnagowan, Tipperary.

Mr Grant was crime scene manager at Mary Lowry's farm on the day the remains of Bobby Ryan were found. He said tests to identify traces of blood were carried out in the house, farmyard and outhouses.

The tests were positive for blood on a ceiling and light fitting in a sitting room. Blood traces were also found on the bed frame, mattress and floor in Mary Lowry's bedroom and on wardrobe doors and base.

He said the doors and light fitting were taken away for analysis. The court has not yet heard the result of that analysis.

Mr Grant also said that one member of the garda technical team suffered an adverse reaction during the removal of Mr Ryan's remains from the run-off tank that he had to call in welfare services on their return to Dublin.

He said he did not believe Mr Ryan's remains could have been examined in-situ but it was up to the pathologist to decide whether or not to attend. He believed the fire service personnel who had chemical suits were the best equipped to remove the body from the tank.

He also attended the post-mortem examination and said the pathologist listed a number of blunt force trauma injuries, which he said would have caused death within minutes.

These included multiple fractures to the face and head along with a broken rib and leg bone.
