The occupant of a Ravenswood property where a man was allegedly bashed with a hammer and injected with saliva heard nothing on the night of the incident, Launceston's Supreme Court has heard.
Ann Louise Wooders told the court she was at home on April 17 and 18, 2012, when Nathan Henry John Riley allegedly assaulted Timothy Robert John Saggers in a caravan and then a shed on the property.
Ms Wooders said she had never before seen the blood stain found by police in her shed but she had stored a dead cat and wallaby in there previously and they may have bled.
Mr Riley, of Waverley, has pleaded not guilty to attacking Mr Saggers.
The court has heard none of the items taken from the scene, including a hammer and metal tube used to bash Mr Saggers, contained the accused's DNA.
The trial continues.
