A Mongrel Mob president has been sentenced to at least 10 1/2 years in jail for the murder of a rival gang prospect in an unexpected and brutal slaying.

Head of the West Coast chapter, Turanganui John Ormsby-Turner, killed Rei Joseph Tumatauinga Maihi Marshall, a prospect for rival gang Uru Taha, last August.

Marshall, a 23-year-old Taranaki father-of-two, died after he was attacked with a claw hammer and stabbed with a large hunting knife.

Ormsby-Turner, 26, earlier admitted the murder and today was sentenced by Justice Peter Churchman in the High Court at New Plymouth.

In a victim impact statement to the court, Marshall’s mother Julie Marshall said shortly before her son was killed he texted her to say he would visit within the hour.

But instead, she received a call saying he was at the hospital and had been badly beaten.

“I started to scream hysterically.”

When she got to hospital she was met with “a line” of police and was told “Rei had gone”.

In the aftermath of her son’s death, she and Marshall’s father slept in a car outside the funeral home where their son’s body lay. They were not permitted to see him.

“Time was so slow waiting to touch him.”

When they finally did he was “cold and lifeless”, had a chunk missing from his forehead, and “every piece of him was bruised”.

She had not seen any remorse on the faces of the three involved in Marshall’s death.

They were “cold-hearted murderers” she said.

Marshall rang his mother daily. But the phone had stopped ringing and the reality of his death was setting in. Her son would never get to see his daughters grow up.

“Everyday I live the nightmare of them taking my baby’s life.”

Crown prosecutor Cherie Clarke said the primary aggravating factor in the case was the connection between Ormsby-Turner as president of a Mongrel Mob chapter and his determining to kill a prospect of an opposing gang.

She submitted Ormsby-Turner should receive a minimum term of imprisonment of 12 years.

Defence lawyer Paul Keegan accepted his client faced life in jail but said the murder was committed without any significant premeditation.

It was a spontaneous reaction occurring as a conflict unfolded between Marshall and Hamiora Laupama.

“It is also, tragically, borne out of longstanding animosity of two rival gangs.”

Keegan said mitigating factors included Ormsby-Turner’s early guilty plea, relative youth, and his limited history before the court.

He said a pre-sentence report noted Ormsby-Turner showed remorse and he hoped the sentence he received would bring some peace to Marshall’s whānau.

The final sentence should be life with a minimum period of imprisonment between 10 and 11 years, Keegan submitted.

Referencing reports provided to the court, Justice Churchman said Ormsby-Turner was exposed to alcohol and violence at a young age, as well as other traumas.

He had tried to stay away from gangs but they had “sucked him back in”.

Ormsby-Turner told the report writers he knew his actions were wrong and that he never intended to kill Marshall.

He was “100 per cent sorry” and hoped to one day participate in the restorative justice process with Marshall’s whānau.

Justice Churchman accepted the defence’s submission that it had a spontaneous component to it.

“You were not actively seeking out the victim for a confrontation.”

Ormsby-Turner stabbed Marshall only once and then assisted in getting him into the vehicle so he could be taken to hospital.

However, he said aggravating features included the use of a weapon, the loss of life and the extent of Marshall’s injuries, the pain caused to the victim’s whānau, the gang element, and that there were multiple offenders.

Justice Churchman took a starting point of a minimum of 13 years, making deductions for Ormsby-Turner’s guilty plea, personal circumstances, and rehabilitation, resulting in an end sentence of life imprisonment with a minimum period of 10 1/2 years.

Ormsby-Turner turned and waved to his whānau as he left.

The murder

On the evening of August 3, Ormsby-Turner, along with Laupama and the teen, arrived at a South Rd address in New Plymouth.

They were there to pick up another Mob member with the foursome intent on “taxing” someone who owed Ormsby-Turner money.

But when the gang member arrived as planned, he had his brother with him - Marshall.

Despite his brother’s Mob patch, Marshall was connected to rival gang Uru Taha.

Given Marshall’s brother’s connection to the Mongrel Mob, Marshall had been around the gang before without any trouble and it was believed this encounter would be no different.

But because of wider issues between the opposing gangs Ormsby-Turner and the teen became agitated when they saw him.

Shortly after, Laupama and Marshall crossed paths while inside the South Rd property.

They had a heated exchange and Marshall threw a punch at Laupama but missed.

The situation soon escalated as Ormsby-Turner came up behind Marshall and stabbed him in the torso with a hunting knife. The teen stepped in and began to rain blows on Marshall with a claw hammer.

Marshall’s brother intervened, bringing the attack to an end by picking up his sibling and carrying him to the car.

They were then driven to Taranaki Base Hospital by a woman but Marshall was pronounced dead shortly after they arrived.

What followed was an attempt by Laupama and the teen to cover up the murder at the instruction of their boss, Ormsby-Turner.

Laupama and the teen moved their car from the scene and dumped several items, including the knife, at East End Reserve in New Plymouth.

They got rid of the clothes they were wearing at the time of the murder by burning the items in the backyard of an associate.

On August 8, police executed a search of Ormsby-Turner’s house and the three were arrested. Officers later located items of interest at the reserve and the associate’s address.

Tensions boil over outside court

Mongrel Mob members shouted the Nazi cry Sieg Heil as Ormsby-Turner was driven away from court to begin his life sentence.

Police moved in on the group outside the High Court to keep tensions under control.

The heightened security follows the sentencing of Ormsby-Turner’s co-offender Hamiora Laupama in December when a shouting match exploded between the two sides in the public gallery.

The same eruption occurred at an earlier hearing when Ormsby-Turner entered his guilty plea to the charge.

Laupama, 25, and a 16-year-old boy, both members of the Mongrel Mob at the time of Marshall’s death, were also charged with his murder.

However, those charges were later withdrawn and the two then admitted to being an accessory after the fact.

The teen, who has interim name suppression, also pleaded guilty to wounding with intent to cause grievous bodily harm in relation to the death.
