The Discovery That Shook Rural New Zealand
On a quiet Saturday afternoon, December 13, 2025, the tight-knit farming community of Ruatiti in New Zealand's central North Island was forever changed. Brendon Leigh Cole, a 56-year-old sheep farmer, and his wife Trina Michelle Cole, 54, were found dead in the driveway of their rural property on Murumuru Road. The property, located about 21 kilometers southwest of National Park and nestled near Whanganui National Park, is in one of the most remote parts of the country. Police were called to the scene around midday, launching what would become one of the most intense homicide investigations in recent regional history.
The Coles, known locally for their dedication to farming and community involvement, were discovered by a family member or acquaintance checking on their welfare after they had not been heard from. Initial reports described the scene as gruesome, with the couple having suffered fatal injuries consistent with a violent attack. Post-mortems confirmed homicide, though specific cause-of-death details, such as gunshots from a firearm, were withheld to protect the investigation. This rural driveway, typically a place of everyday farm routines like loading livestock or heading to the paddocks, became the site of unimaginable tragedy.
Immediate Police Response and Public Alert
Central District Police swiftly classified the deaths as a double homicide, establishing a scene guard and cordoning off the 100-hectare property. Detective Inspector Gerard Bouterey led the operation, appealing for public assistance early on. Within days, on December 15, they named 29-year-old Mitchell Cole—the couple's son—as a person of interest. Mitchell, described as an exceptional bushman with intimate knowledge of the surrounding rugged terrain, was believed to have fled into the dense Ruatiti bush.
Public warnings were issued immediately: 'Do not approach.' Police described Mitchell as 1.8 meters tall, solid build, with short dark hair, often accompanied by his large Blue Neapolitan Mastiff dog named Rumble. Searches focused on hunter cabins and remote tracks like Mangapurua and Kaiwhakauka, which were temporarily closed. A second unidentified man, tall and athletic in a singlet and shorts, was sighted nearby around 6pm that day, adding layers to the inquiry.
The Intense Manhunt in Rugged Terrain
The manhunt mobilized dozens of officers, helicopters, dog units, and even local volunteers familiar with the area. Ruatiti's landscape—steep valleys, thick native forest, and fast-flowing rivers—posed extreme challenges. Mitchell's survival skills, honed from years hunting and tramping, meant he could evade capture indefinitely using trappers' huts for shelter and food. By December 19, a warrant was issued for unlawful firearm possession, hinting at a weapon's role.
Community members reported eerie sightings and shared trail cam footage, but leads dried up. Friends of the Coles expressed devastation, recalling Brendon's passion for sheep farming and Trina's warm hospitality at local events. 'Horrendous,' one neighbor said, capturing the shockwave through the valley's 50-odd residents.
Mitchell Cole Turns Himself In Amid Mystery
On Christmas Eve, December 24, 2025, Mitchell Cole walked into a police station in the central North Island, ending the 11-day search. He was questioned extensively but released without charge initially. Heavy name suppression was granted in related court appearances, fueling speculation. Police confirmed no immediate link but continued forensic work at the property, including ballistics analysis.
By early 2026, the case stalled publicly, with no arrests. Then, in March, a breakthrough: appeals for info on a missing semi-automatic shotgun, believed modified by having its barrel cut down. This firearm, potentially central to the killings, remains at large, prompting renewed calls for tips.

Breakthrough: Murder Charges Filed
Five months after the bodies were found, on May 7, 2026, police announced a 30-year-old man—widely understood to be Mitchell Cole—had been charged with two counts of murder. He appeared via video link in Whanganui District Court, facing the gravity of allegations that he killed his father and stepmother (Trina was reportedly his stepmother). Detective Inspector Bouterey called it a 'significant milestone,' praising the team's persistence and community support. 'Considerable work remains,' he noted, urging info on the shotgun or any related movements.
The charges mark a pivotal shift, but suppression limits details on motive, evidence, or exact timeline. Bail was not granted, with the man remanded in custody for further hearings.
Profiles: Brendon and Trina Cole's Lives
Brendon Cole embodied the resilient Kiwi farmer, managing sheep on challenging terrain while contributing to local dog trials and hunting clubs. Neighbors remembered his dry humor and tireless work ethic, often helping with musters or fence repairs. Trina, vibrant and community-oriented, organized events and supported rural charities. Together 30+ years, they built a life in isolation, valuing self-sufficiency amid Ruatiti's paradise-like scenery.
Their deaths robbed the area of pillars. Tributes poured in: 'Generous souls,' 'Salt of the earth.' Mitchell, living nearby, had a reportedly strained relationship, though details are scarce.
Ruatiti: Paradise with a Shadowy Past
Ruatiti, a speck on the map 40 minutes west of Raetihi, offers stunning views but harbors isolation's risks. Its 'dark past' includes prior unsolved homicides and tragedies, like the 1970s Crewe murders echoing rural vulnerabilities elsewhere. Remote farms face delayed emergency responses—hours for ambulances or police in bad weather.

Stats:
- Rural burglaries up 41% repeats.
- Farm theft claims rose at insurers like FMG.
- Illegal hunting, boy racers prevalent.
Legal Road Ahead and Police Appeals
The accused faces High Court transfer soon. Prosecutors must prove intent beyond doubt, piecing forensics, witness statements, timelines. Motive unknown—family rift? Inheritance? Shotgun recovery critical.
Police urge: Call 105 with info. Community vigilance credited. As Ruatiti heals, justice pursuit unites them.
