Police are still investigating who killed Tirau woman Roma Joseph in a house fire in May.
Taupo area manager investigations Detective Senior Sergeant Matt Cranshaw said the 58-year-old's death will appear on tonight's episode of Police Ten 7 in the hope it will draw out vital information needed to help solve the near four-month-long case.
Joseph, also known as Roma Midwood, lived alone in her Little St home but family often stayed with her.
She was home alone the night of Monday, May 1, when somebody deliberately set fire to it between 3am and 3.30am.
Cranshaw said her death had devastated her family.
"We urge people to come forward, do the right thing for Roma's family and tell us what they know."
Joseph's death also shocked her neighbours, some of whom were woken by the blaze and recalled seeing people outside of the home just before it went up in flames.
The neighbours said they saw two people, one of whom drove off in a silver vehicle and another who took off on foot.
About a minute later the house was on fire. Joseph was found dead inside.
