The man at the centre of a murder investigation was facing multiple drug charges and was about to be sentenced for fleeing police custody when he was killed.

Eli Johnson, 27, died at a house in rural Tauranga on Sunday June 12.

Emergency services were called to his home in Whakamārama around 8.35pm, and Johnson was found at the address with critical injuries.

More than a month on, police are yet to arrest anyone in the homicide case.

Court documents show that Johnson was due to appear in Tauranga District Court this week on ten separate charges, including methamphetamine offenses, reckless driving, fleeing police and shoplifting.

He was also due to be sentenced for breaching the conditions of his intensive supervision - a community-based sentence handed down to offenders deemed likely to reoffend, which aims to help with reintegration and rehabilitation.

'Intensive” supervision is reserved for medium-to-high risk offenders. It includes stringent monitoring requirements to probation officers, and is a stronger version of regular community supervision.

Since the murder, a member of Johnson's family has sought to raise money for extra security at their home, saying they needed help to feel safe.

'After the traumatic events that have recently taken place at our Whanau Papakainga, trauma and fear are now a very real part of my everyday life,” the family member, who asked not to be named, says in the Givealittle post. 'I need to put security fencing around our home, a step towards trying to be ok again … I am desperate to get this done asap. I appreciate any help you could give me, a little goes a long way.”

The fundraiser has so far attracted $3800 in donations.

When approached by Stuff this week, the family member says they were desperate for police to make an arrest in the homicide investigation. They had very little information about how the investigation was proceeding, they say.

Immediately after the murder, police called for anyone who was in vicinity of Old Highway between 5pm and 9pm on Sunday night to make contact with the investigation team.

Detectives were particularly interested in viewing dashcam footage recorded by motorists in the area at the time.

Subsequently, police released an image of two cars on the Te Puna roundabout on the night of Johnson's death. One was a white ute, the second a silver sedan.

Detective Inspector Lew Warner while his team had identified and spoken with the occupants of the white utility 'we'd like the occupants of the silver sedan pictured to come forward and speak with us.”

Police refused to comment on whether Johnson's previous charges were linked to the case.

Anyone who has information that may help, can contact police on 105 and quote file number 220613/3065.

Information can also be provided anonymously to Crime Stoppers on 0800 555 111 or www.crimestoppers-nz.org.
