Police investigating the brutal murder of a much loved Tirau grandmother say the 58-year-old was seriously assaulted before her house was deliberate set on fire.
A person seen on CCTV footage walking on the main street in Tirau is now being sought by police in connection with Roma Joseph's violent death.
She died in a fire at her Little St, Tirau, home between 3am and 3.30am on Monday May 1, 2017.
Police believe Roma was seriously assaulted before the fire was lit at the address.
The case featured on Police Ten 7 tonight, when detectives released details of footage from the Caltex Tirau service station of a person seen walking north on State Highway 1 about 3.18am.
They are asking this person to come forward to see if they have information to assist the investigation.
Detective Senior Sergeant Matt Cranshaw, Taupo area investigations manager, said police were not suggesting this person was involved in Joseph's death.
"The fact that they were in Tirau at the critical time may mean they can provide information that is useful to this inquiry."
Cranshaw said neighbours in the area were alerted by activity.
"A series of thumps were heard coming from Roma's house. One person was seen walking along Little St away from the address, another was seen up by the front door."
Shortly afterwards a silver four door sedan was seen reversing out of the driveway before driving off towards Bear St.
The family are seeking answers into Joseph's callous and senseless death.
"Roma was a tiny woman in her late 50s. She was violently killed in her own home in the early hours of the morning. Those responsible for this cowardly and brutal murder need to be held to account," Cranshaw said.
"It's really important that people come forward with any information they have whatsoever on the silver sedan or the people seen at and near Roma's place or on State Highway 1 on the morning of 1 May.
"We urge those people with information about this shocking death to do the right thing and tell us what they know."
