A jury will soon decide if the three-decades-old mystery of the fatal Red Fox Tavern robbery has been solved by police.
A man with name suppression and Mark Joseph Hoggart are on trial for the 1987 aggravated robbery of the pub and murder of its owner, Christopher Bush, in Waikato.
The Crown has argued they are the two heavily disguised robbers who burst in through a back door of the Maramarua tavern on Labour Weekend.
It is alleged the unnamed accused fired a sawn-off double-barrelled shotgun, killing Bush before his three staff members were tied up and just over $36,000 stolen.
Defence lawyers have repeatedly said that the wrong men are on trial.
In a circumstantial Crown case the analogy often drawn is that of a rope, he said, as any one strand alone might not support weight but all strands combined can.
"The logic that underpins a circumstantial case is that the defendants are either guilty or the victims of an unlikely series of coincidences," Justice Woolford said.
In the Crown case the defendants were prison mates, known to be associating on the outside, with movements each side of the fatal night consistent with the offending, he said.
The prosecution further argued the defendants' own accounts of their whereabouts that night could not be corroborated, he said.
The delay meaning recall may not be completely accurate, the court heard.
Wellington defence lawyer Christopher Stevenson had also argued there was no real similarity between the earlier aggravated robbery committed by his unnamed client and the fatal Red Fox Tavern robbery.
In the defence case the unnamed accused did have a few thousand dollars when he left prison and had a means to make more, Justice Woolford said.
Possession of firearms also was relatively common in the unnamed man's circle of friends, the court heard.
A theory that is opposed by the Crown who have said Hamilton's alibi rules him out. Stevenson disputes this.
Justice Woolford said before the jury could even consider the defendants, they had to rule out a reasonable possibility that Hamilton was one of the offenders.
He was initially the "prime suspect" who police say they eliminated in the course of their investigation.
