UPDATE: A forensic pathologist has detailed the multiple fractures likely caused by blunt force suffered by alleged murder victim Cleveland Paul Clay.
Dr Rohan Samarasinghe appeared as a witness before the Maryborough Supreme Court on Thursday in the trial of Simeon Frederick Blair.
Dr Samarasinghe performed a post mortem examination of Mr Clay, who had close to 50 external injuries such as bruising, lacerations and abrasions.
He also detailed fractures on Clay's face, right side, left side and top of his skull.
Four other witnesses also appeared before the trial today to give evidence about the hours before Blair allegedly attacked Mr Clay at the back of the Carlton Hotel.
EARLIER: Townsville man Cleveland Paul Clay was planning a week-long stay in Maryborough less than 12 hours before an alleged violent attack by a man now charged with his murder.
The trial of Simeon Frederick Blair has heard how the two men met on April 27, 2012 while out drinking in Maryborough.
Blair is now charged with murdering Mr Clay with a piece of discarded wood at the back of the Carlton Hotel in the early hours of April 28, 2012.
Three men who met Mr Clay the day before the alleged attack appeared before the trial in the Maryborough Supreme Court on Thursday to give evidence.
The court heard both Blair and Mr Clay had been drinking on the night and Mr Clay had been smoking cannabis with residents of the Carlton Hotel.
Mr Clay had approached patrons at the hotel and its bar manager about accommodation some time after 2pm on April 27 before paying $150 in cash for a week-long stay in one of the upstairs rooms.
The court heard he then drank and smoked with some of the patrons in their rooms at the Carlton and also went out to several other Maryborough pubs before meeting up with the group that included Blair and several other people.
One witness, who was 16 at the time of the alleged attack, said Clay had begun threatening Blair and challenging him to fight when the group had made its way back to the Carlton Hotel.
The jury was also shown photos taken by Senior Constable David Mayes at the scene of the alleged attack.
Sen Const Mayes and his partner were the first officers tasked to the Carlton Hotel about 1.45am on the morning Mr Clay was injured.
The officers had to use a make-shift shelter to preserve evidence, including a large pool of blood, from the rain.
The photos show the extent of Mr Clay's head injuries and blood loss and were tendered as evidence.
More than 30 exhibits have been tendered in the first three days of the trial and more than seven witnesses have also appeared.
The trial will continue into next week.
