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.
