A woman has described the moment a masked gunman walked into the Ashburton Work and Income centre, which made her "freeze" and stand still.
Lucy Annabel Waller went to the Winz office on Cass St on the morning of September 1, 2014, to drop off a form.
While waiting in line at reception, she saw a man walk in wearing a black balaclava, in a slightly "wonky" fashion, and holding a gun down the right side of his body, with the barrel pointing to the floor.
"I just froze and stood still," she told day four of the High Court trial in Christchurch of double-murder accused Russell John Tully.
Ms Waller, a sport trap shooter, described the gun as being a semi-automatic shotgun with a short barrel, approximately 40cm long, which looked as if it had been "cut off".
She also described the gunman's skin as having "blotchy red patches" on his neck and hands.
Ms Waller's evidence is part-heard and she will continue her testimony at 2.15pm today.
At 9.51am on September 1, 2014, a masked gunman walked into the Ashburton Winz office and shot and killed receptionist Peggy Turuhira Noble (67) and case manager Susan Leigh Cleveland (55).
Tully denies being the shooter. He also denies attempting to murder two fellow workers Lindy Louise Curtis and Kim Elizabeth Adams and other charges that include two counts of unlawful possession of firearms, and one of setting a mantrap.
Earlier today, the court heard that Tully allegedly threatened a Winz manager with legal action before hanging up on her just three days before the killings.
Tully was a "difficult" client who appeared almost daily at the Ashburton Winz office, often without an appointment, Hornby Heartland's Winz service centre manager Olivia Monk told the court.
He was soon trespassed from the office for his behaviour, the court has heard.
Ms Monk said she first became aware of Tully when colleagues at the Rangiora service centre let her know that a man was moving to her district who had been "so difficult to deal with".
Tully made numerous applications for grants and benefits, she said.
After he was trespassed in early August, Tully phoned the Winz contact centre to complain he was declined an appointment, Ms Monk said.
Ms Monk says she explained the reasons he'd been trespassed. Tully then threatened her with a lawyer and then hung up on her, the jury was told.
She also said Tully had written to Work and Income on two occasions, signing off only as "X".
On the second occasion, he wrote to say he wished he would only see Jane Hayman as he had had problems with a "Lee Adams".
Ms Monk said there was nobody at the centre by that name, and she took it that Tully meant either Ms Cleveland or Ms Adams.
Tully (49) was removed from court this morning after his second outburst before the jury claiming that his trial is "fixed".
At the start of the day's proceedings, Tully interrupted to say, "Excuse me your honour, I require to go see a doctor".
Justice Cameron Mander repeatedly asked him to be quiet.
But Tully said that he needed a doctor, and that he has been asking to see one for six months.
Tully claimed he has been on a hunger strike for two weeks.
He also said he needed a lawyer and claimed that he has not received any disclosure.
Tully is not be represented in court by his own defence counsel. Instead is legally assisted by two amicus, or friends of the court, lawyers Phil Shamy and James Rapley.
While Justice Mander tried to warn Tully to be quiet, he repeatedly claimed that the judge is corrupt.
"Trial fixing by Judge Mander," said Tully who was restrained in a wheelchair surrounded by prison guards.
After three minutes, he was removed from court.
Tully was ejected from court on day two last week after a similar outburst.
Justice Mander today repeated his directions to the jury to ignore that outburst.
He said there was a "background"to Tully's conduct in court today, but he told the jury that it was not relevant to their task.
The judge instructed the jury to simply concentrate on the evidence.
Identification of the masked gunman is key to the trial, the trial has heard.
The Crown says evidence that the shooter is Tully is "overwhelming".
Three witnesses this morning gave evidence relating to security camera footage from around Ashburton which shows the alleged shooter cycling around the town on the day of the murders.
Ashburton's East Street Pharmacy store manager Barbara Glassey said a man she knew as being Tully after seeing him in a local newspaper article complaining about his homelessness situation came in regularly.
He always wore a beanie and bought bottles of six per cent hydrogen peroxide in cash, she told the court.
Tully was "quite chatty some days", she said.
But on the morning of September 1, 2014, when Tully came into the pharmacy at around 9.15am - 36 minutes before it's alleged he walked into the Winz centre with a gun - he bought his peroxide but "didn't say anything at all to me, which I thought was quite unusual".
"I just thought he was a having bad day," Ms Glassey said.
