UPDATED: 6.57PM The judge in the trial of Russell John Tully said the jury has made a sensible decision to pause its deliberations and restart tomorrow morning.

The jury of six women and four men have to consider whether Tully is the gunman who shot dead Ashburton Work and Income receptionist Peggy Noble, and case manager Leigh Cleveland in September 2014.

He’s also charged with attempting to murder two other case managers, Kim Adams and Lindy Curtis.

The jury deliberated for an hour, before asking to go home for the night.

Justice Cameron Mander said that was completely understandable.

"You've had to listen to three long addresses today and it takes a lot out of you, concentrating that long. So accordingly, I'll release you for tonight."

Earlier, Justice Mander reminded the jury to pay no attention to Tully’s previous outbursts, saying it was irrelevant to the job ahead of them.

Tully has only been present in court for two out of ten days, and was removed on two separate occasions for outbursts.

Justice Mander told the jury it was an unusual situation but it shouldn’t read anything into it.

"Regrettable as it may be, it has simply been a circumstance of this trial, and your role in the case has been no different, and continues to be no different, because of that fact," he said.

Justice Mander also told the jury not to speculate on why Tully has been restrained to a chair in the middle of the court, surrounded by four prison guards.

The Crown said the evidence against Tully is overwhelming.

Crown prosecutor Mark Zarifeh told jury in the High Court trial the only proper verdict they can return is guilty on all counts for 49-year-old Tully.

He said: "There are a lot of strands of evidence that, all woven together, all point to that inescapable conclusion."

Zarifeh told the jury an amazing set of coincidences would have needed to take place, for the shooter to be anyone other than Tully - like wearing the same clothes, having a grudge against WINZ and having the same movements as Tully the day of the shooting.

He said evidence includes the clear grudge Tully bore against WINZ.

"Over that period of time, that's July to September, there were no other clients of the Ashburton WINZ Office that they were having the kind of issues they were having with Mr Tully".

The Crown has encouraged the jury to ask why Tully was found in a hedge, in the middle of nowhere, if he had done nothing wrong.

Zarifeh said Tully was inside the hedge, because he was trying to evade capture.

"If he'd done nothing wrong, why was he hiding?

"The answer's simple. He was hiding because he was trying to escape after the shooting. He knew the police were onto him and were looking for him".

Zarifeh has also pointed to a distinctive green jacket Tully was seen wearing before the incident, that is identical to the one CCTV footage shows the gunman wearing during the shootings.

He said it was "just like" the one the gunman wore.

James Rapley, the amicus assisting Russell John Tully said “just like” isn’t good enough.

"'Doesn't it look similar?' Those are his exact words. 'Doesn't it look similar?' Ladies and gentlemen, it doesn't have to look similar, it has to be the same."

Rapley said the Crown should have carried out forensic imagery analysis to compare CCTV footage at WINZ, with footage of Tully in other shops.

He said the jury needs to challenge, and question each piece of evidence.

Earlier Rapley told the jury that evidence identifying DNA that matched Tully on a helmet dropped by the gunman isn’t relevant.

"What it tells is that Mr Tully's DNA was on that item. What we don't know is how it got there. What we don't know is when it got there," he said.
